It was possible to start the computer recovery. What to do if Windows won't start

Mar 3 2015

How to recover Windows system 7 on a laptop, a black screen appears when booting, the recovery environment does not work, I deleted all the hidden partitions, there is no original Windows 7 disk.

Spent a lot of time, tell me what to do now, or at least how to insure myself against such situations in the future, preferably without using paid data backup software.

How to restore your Windows 7 system

Unfortunately, the reasons for this trouble are enough, ranging from incorrectly written drivers, harmful actions of a virus, errors file system and ending with our erroneous actions when working with a computer, there is no need to be afraid of such problems, you need to learn how to deal with them effectively.

Let's think about how to restore the windows 7 system, as well as insure ourselves for the future from possible troubles using the built-in operating system backup and recovery tools.

We will learn how to restore Windows 7 without applying third-party programs on backup even when the System Recovery Options are not loaded and the F-8 button will be useless.

Has in its arsenal a fairly powerful and good tool -> Recovery environment, which is created automatically when Windows installation 7 in a hidden section and contains five other tools that solve numerous malfunctions and malfunctions.

Note: If you learn to use the right tools Windows recovery 7, and this is not difficult, you can do without additional and paid data backup programs.

You can start the recovery tool by pressing the F-8 button on your keyboard immediately after starting your computer. After that, a menu will open in front of you Additional options boot: Troubleshoot computer problems, then Safe Mode, Safe Mode with Boot network drivers etc.

Small digression: Before choosing Troubleshoot computer problems, try the easier option - Last Known Good Configuration - in simple words, the operating system always remembers the last successful boot of the computer and enters this information into the registry.

If there are problems with loading, Windows can remember the registry parameters and driver settings that were used at the last successful boot of the system and use them if you select the Last Known Good Configuration option.

If this tool does not help, select the first -> Computer troubleshooting,

Next, we get to the Windows 7 System Recovery Options menu, we need it, it is here that we can select the System Restore Tool we need, there are five of them, let's take a closer look at how they all work.

The first thing to do is apply Startup Repair (Automatically fix problems that prevent Windows from starting).

Desired digression: After pressing the F-8 button when the computer boots, you may not have the item> Troubleshoot computer problems, but only Safe Mode and so on, the question arises why.

When installing Windows 7, the recovery environment partition is created automatically and is located in the root of the drive (C :) in the Recovery folder. You can also see in the Disk Management window - a separate, hidden partition of the hard drive, it has only 100 MB in size, it is used to store boot configuration files (BCD) and the system boot loader (bootmgr file).

You can see it on Computer-> Management-> Disk Management. In no case should you delete this partition (many people delete it out of ignorance), otherwise you will not start the recovery environment, that is, you will not have the item Troubleshooting computer problems, and in more severe cases, you simply will not boot the system.

On the lower screenshot, you can see another hidden partition, with a volume of 9.02 GB, this is a hidden recovery partition with the factory settings of my laptop, you may have it larger or smaller. It is also better not to delete it, if necessary, you can always restore Windows 7 from it.

What to do if you do not have a partition with the recovery environment and when you press the F-8 button in the Advanced Boot Options menu, the item Solving computer problems does not appear? How do you restore your Windows 7 system then?

Can save here installation disc with the operating system Windows 7. You can run the recovery tool by booting from the original installation Windows disk 7, selecting at the very beginning the System Restore item.

If you do not have the installation disc, then you can use the Windows 7 Recovery Disc (you can make it in any running Windows 7) in five minutes, then you can also boot from it and do the same.

So, we still got to the System Recovery Options, either using the F-8 button and the Troubleshoot item, or the Windows 7 installation disc or Windows 7 Recovery Disc.

In the Select System Restore Tools menu, select the first:

Launch recovery-> an analysis of malfunctions interfering with the normal loading of Windows 7 will occur and their further correction for the normal loading and functioning of the operating system.

In the process, we may be warned that problems have been found in the boot parameters, click Fix and restart.

System Restore-> using this function, we will be able to select a previously created system restore point, if we have it enabled, and roll back to the time when our Windows 7 worked fine and booted, everything is simple here.

System image recovery-> I personally use this tool, with skillful use it can be replaced paid programs on data backup, if interested, read on.

What is it good for? It will help when you do not have the original Windows 7 installation disk and you deleted the hidden partition with the factory settings of your laptop, but that's not all.

Sometimes there are situations when, for various reasons or due to the actions of a virus, you will not be able to boot the operating system at all, or many ask How to restore the Windows 7 system, even if the menu with Additional boot options is also unavailable. Reinstall the operating system again?

Therefore, immediately after installing Windows 7 on your laptop or computer, using this function, we create an archived image of our Windows 7 on the hard disk using this function -> System Image Restore, we save it.

Be sure to create a Windows 7 Recovery Disc (see below), it will help you use the System Image if the Advanced Boot Options menu will not load.

We go to Start -> Control Panel -> Archiving computer data.

We select "Create a system image".

In my case, Local disk (E :), if you have system unit several hard drives, then of course it is better to place the backup on the hard drive where the operating system is not installed.

By default, the data backup program will select the partition with the Windows 7 operating system itself, if you wish, you yourself can add Local drives for archiving, if only you have enough space.

Note: You can see that I have two operating systems installed on a laptop, so the backup program selected two Local drives.

Click Archive and the process of creating an archive with our Windows 7 will begin.

Created, it will look like this.

Now, if necessary, you can deploy the archive with Windows 7 to your computer in 20-30 minutes. It will be better if you copy the archive with the system additionally to a portable hard disk, this will make you doubly safe.

Let's imagine that we cannot start Windows 7 and deploy the backup we created, do it together.

We launch the Windows 7 Recovery Tool by pressing the F-8 button on the keyboard immediately after starting the computer.

The Advanced Boot Options menu opens, select Troubleshoot computer problems.

System image recovery

Use the latest available system image.

Of course, all our data is on Local disk where the operating system is currently being restored will be deleted, so you can pre-boot from any Live CD and copy what you need.

How else can you restore your Windows 7 system? With the help of Windows 7 Recovery Disc, of course.

Let's create one that can be used to boot the computer, it will contain recovery tools with which you can restore Windows 7 boot faults, as well as restore the operating system from an archive copy that we created in advance.

Important: The system's bitness is important for the recovery disk, you can use a 32-bit recovery disk for any 32-bit Windows 7, and a 64-bit recovery disk for any 64-bit Windows 7.

Going again Archiving computer data.

Create a system recovery disc, insert the DVD into the drive, click "Create Disc".

When the Windows 7 bootable Recovery Disc is ready, put it in a safe place.

In order to restore Windows 7 from the Recovery Disc, you do not need, in principle, any working operating system at all.

You only need to change the boot priority to the floppy drive in the BIOS of your computer, insert the recovery disc into it and restore your Windows 7 using the archive.

Many people here can draw an analogy with data backup programs and this is correct, they work according to the same principle, only the functionality is of course more convenient for them.

Recovering Windows 7 from the Recovery Disc. I am showing you how to do it. Let's say we are in trouble, we cannot start Windows 7, when we press F-8 on the keyboard immediately after starting the computer, nothing happens.

We cannot get into the menu with Additional boot options and an error message is displayed. In this case, the system archive on the hard disk is not available to us. It was this kind of trouble that happened to our reader Ilya, who wrote us a letter asking for help.

In this situation, many reinstall Windows 7 from scratch, but not you and me, because we have a System Restore Disc.

We insert it into the floppy drive and reboot, set it to BIOS boot from the drive, as I said the boot disk, the System Recovery Options program is launched.

Press Enter until the offer to boot from disk disappears.

An automatic recovery tool running from a disk will try to restore Windows 7 to start.

If all else fails, choose any tool, try, for example, Restoring your computer using a previously created image of the operating system.

We use the last available system image.

What other ways are there to restore Windows 7?

There is another little-known way to restore the boot of Windows 7 after a crash, and I'll tell you about it. At first glance, it will seem difficult to many, but nevertheless it often helps me out.

The fact is friends that a very large part of the problems due to which you cannot boot Windows 7 lies in registry errors. And Windows 7 wouldn't be Windows 7 if it didn't have a mechanism to protect registry files. Such a mechanism exists and creates archive copies of the registry in the RegBack folder every 10 days, regardless of whether you have system restore enabled or not.

If you cannot solve problems with booting Windows 7, you should try replacing the existing (and apparently damaged) registry files from the Config folder with archive files from the RegBack folder. To do this, we will have to boot the computer from a Windows 7 installation disc or a Windows 7 recovery disc.

Boot into the recovery environment, select the command line.

We type in it - notepad, we get into Notepad, then File and Open.

We go into the real explorer, click on My Computer. Now we need system disk C :, attention, the drive letters here may be confused, but the system drive C: I think you can find out by the inside system folders Windows and Program Files.

We go to the C: \ Windows \ System32 \ Config folder, here are the current registry files, indicate the File type - All files and see our registry files, we also see the RegBack folder, in which the Task Scheduler makes a backup copy of the registry keys every 10 days.

So, we will replace the current registry files from the Config folder backup files registry from the RegBack folder.
So, first of all, let's delete from the C: \ Windows \ System32 \ Config folder the SAM, SECURITY, SOFTWARE, DEFAULT, SYSTEM files, which are responsible for all the registry hives (my advice is to copy the registry hives somewhere, just in case, before deleting them).

In their place, copy and paste files with the same names, but from backup, that is, from the RegBack folder.

Note: All files SAM, SECURITY, SOFTWARE, DEFAULT, SYSTEM cannot be deleted, delete them one by one. Then copy the same files from the RegBack folder in their place.

Friends, if this does not help, apply Windows 7 file integrity recovery, if the operating system does not boot, it is done in the same way as in Windows 8.

What else do we have from Windows 7 recovery tools?

Memory Diagnostics 7-> checks the system memory for errors. Command line-> using it, you can delete files that interfere with the boot of Windows 7.

I hope our article on how to restore your Windows 7 system helped you.

The computer does not turn on, writes the startup recovery. Startup Repair Tool does not work

This article describes a method that you can use to fix a boot disk error that says that.

Hello. I think there are many of those who have at least once encountered a problem Windows startup and tried to fix it with boot disk or the system itself:

stumbled upon a repeated message stating that the startup repair tool is powerless. Almost no resource I know offered any clear solution to this problem. And, except to send the user to reinstall Windows, they do not advise anything.

I offer you a solution to the problem of correcting some of the Windows registry entries, which are causing the round-robin failure of the repair tool. In general, the principle is simple - we substitute copy of Windows files from the registry backup. In fact, we will do what Windows itself is trying to do - only we will do it manually and for sure. Works on any of the Windows versions. Or doesn't work ...

Some of the recently installed programs will have to be donated.

BEFORE YOU BEGIN.

I hope that you have already used all the funds; some are very helpful with loading Last configuration with workable parameters
try to follow the advice carefully, otherwise, after rash actions, other means will be completely useless - the system will really be beaten irrevocably
I do not give guarantees, but it's worth checking

On board:

Drive_Letter:

my system disk turned out to be D

check its contents. The fastest way to do this is to enter the command:

dir

if folders appeared in the manner Program Files, Desktop and others, you are in the right place.

go to the Windows system directory:

cd \ windows \ system32 \ config

where we will display its contents again for better navigation with the dir command and create a folder that will contain the files we will work with (in case something goes wrong). I called new folder backup - arbitrary name:

and copy all the contents of the directory to this folder:

copy *. * backup

If the first attempt fails and you have to overwrite the content, press A when asked by the console.

ATTENTION. You shouldn't make any mistakes at this stage. If something went wrong, repeat the work from the beginning step by step.

We are now interested in the contents of the RegBack folder:

cd RegBack

Its content is the same for almost all users and looks something like this (the dir command to help):

The main thing is that there is no empty folders with content of 0 bytes.

Copy the contents of the RegBack folder with the command (follow the syntax):

copy *. * ..

and clicking on Enter will copy the contents to the directory from where the folder is viewed (Windows \ System32 \ config). If the console asks for confirmation, press Y or A.

Close the console and reboot.

Critical errors when starting Windows 7 occur for a variety of reasons: due to hardware malfunction, due to problems with the system itself, or due to software glitches. In some cases, a direct connection between cause and effect can be traced if the failure occurred after installing an application, driver, connecting a new device, etc. In other cases, it is difficult to determine the source of the error.

Hardware problems

The problems that arise before Windows 7 starts booting are hardware-related, so there are literally a few words about them. Any of the devices can be the culprit of the failure, but most often they turn out to be RAM and hard drive. The message that is displayed on the screen in case of a critical error will help you to understand in more detail.

Every user has ever seen (BSOD). We will leave most of what is written there behind the scenes, since only the following is important for us to make a diagnosis:

error type - a line at the top of the screen, written in capital letters through the underscore character (point 1 in the picture);
error code - a numeric identifier in hexadecimal form and its additional parameters (point 2 in the picture);
the driver or application that caused the BSOD, as well as the address where the failure occurred (point 3 in the picture). In case of hardware problems that occur before the drivers initialization and in some other cases, this parameter is absent.

The following data may indicate problems with the hard drive or its controller:

0x00000077 - KERNEL_STACK_INPAGE_ERROR
0x0000007A - KERNEL_DATA_INPAGE_ERROR
0x0000007B - INACCESSIBLE_BOOT_DEVICE
0x00000024 - NTFS_FILE_SYSTEM
0x0000008E - KERNEL_MODE_EXCEPTION_NOT_HANDLED

Memory errors often show themselves with the following messages:

0x0000002E - DATA_BUS_ERROR
0x00000050 - PAGE_FAULT_IN_NONPAGED_AREA
0x00000077 - KERNEL_STACK_INPAGE_ERROR
0x0000007A - KERNEL_DATA_INPAGE_ERROR
0x0000012B - FAULTY_HARDWARE_CORRUPTED_PAGE
0x0000007F - UNEXPECTED_KERNEL_MODE_TRAP
0x0000004E - PFN_LIST_CORRUPT etc.

Often, a malfunction of the RAM is manifested by a variety of errors that can occur at any time during the startup and operation of the computer.

Eliminate uncomplicated hardware failure often helps restore BIOS Setup to default settings or, as they say, reset to default. This can be done in several ways: using your own BIOS option, by switching a special jumper to the mat. board or a temporary power outage of the CMOS chip (BIOS storage location).

Troubleshoot Windows startup problems

Recovery environment

It is much more convenient to restart Windows 7 than Windows XP, which did not have time to get a recovery environment. When installing Windows, this environment is installed on HDD, has a separate section, as well as a separate bootloader. That is why the recovery environment does not in any way address the problems faced by Windows.

To start the recovery environment, press the F8 key and select "Troubleshoot computer problems" from all Windows boot options.

Next, to get into the recovery environment, the system will ask you to enter a password. If you have forgotten your password or do not have administrator rights, you will have to run the recovery environment from the installation disc.

This point is worth resorting to if you do not know the exact reason why Windows does not start.

Select Startup Repair. The system will scan and fix any problems it finds.

This method can be used if Windows stopped loading after installing the program, infecting the computer with viruses or changes in the registry.

The System Restore option will help fix the problem, but only if the restore points have been saved.

The principle of operation is quite simple: you select the desired restore point, which is dated at a time when there were no problems with Windows. The system will roll back and Windows will boot normally.

It is used when there are no backups saved on the computer, but you have a recovery point saved on removable media.

Select System Image Restore, and then connect the removable media containing the system image archive to your computer. Then follow the instructions of the Recovery Wizard.

Manual Registry Repair

Applies when the above instructions did not correct the problem. In OS Windows backup A copy of the registry is created every 10 days, so you can try to download the latest working backup yourself.

From the list of available options, select Command Prompt and type the following command "notepad" into it, then press Enter. The standard Notepad program will start. Select "File" - "Open" in the program header.
Go to directory C: \ Windows \ System32 \ config
At the bottom of the window, in the "Files of type" column, change the option to "All files" to see the full contents of this folder. The following list of files pertains to the current registry: Default, Sam, System, Security, Software (no extension).
Each of these files must be renamed or the .old extension added to them.
In the folder "Config" open the folder "RegBack"... This is where the registry is backed up. Copy them one by one to a folder "Config".
Go back to the window "Recovery options" and at the very bottom select the button. If the problem is caused by a registry malfunction, Windows will start normally.

Recovery files

Windows has a built-in wonderful utility that perfectly restores protected Windows files... On the menu "Recovery options" select item "Command line" and write the following command in it:

/ scannow / offbootdir = C: \ / offwindir = C: \ Windows

Team "Scannow" will start a system scan, "Offbootdir" indicates the letter of the system drive, "Offwindir" leads to the Windows folder.

Please note that in the recovery environment, the drive letters may not match those seen during normal Windows startup. Therefore, before starting the scan, be sure to launch Notepad (this process is described above) and check the letter of the system drive in Explorer.

Manual file recovery

If the above methods did not bring the desired result, you should try to manually restore the boot files, as well as overwrite the HDD master boot record.

Due to viruses, driver mismatches, or software, the OS may crash. If your Windows crashed, don't panic. The situation can be corrected by returning the state of files and programs to the time when the PC was working properly.

Certain errors and problems may occur while running OS Windows 7, 10 or 8. As a result of such failures, a new start of the operating system in operating mode becomes impossible. In this case, it is not at all necessary to do a laborious reinstallation of the OS. It is enough to perform a system restore.

OS recovery using recovery environment

When working, we use the following scheme of actions:

Restart your computer, press the F8 key during boot;
Troubleshooting;
System recovery, choosing an OS restore point;
Click "Further" and again "Further";
Push the button "Ready", we reboot the system (in the Menu, select the boot with the last good configuration).

Windows 7 System Restore

There are several ways that you can resort to resuming the OS. Some of them rely on rolling back to saved parameters. Others simply clear the data.

You can "reanimate" the OS in one of the following ways:

by choosing restore points;
using the command line;
through safe mode;
using the recovery environment;
using an image / boot disk.

Recovering the operating system using the "reanimation" checkpoints of the system is one of the most affordable, effective and popular options. To apply it, you need to carry out a series of clicks:

Panel "Start";
"System Restore";
"Further";
"Select a restore point";
"Ready".

This operation will fix the problem with the computer, discard the changes and return the system to the operating state that allowed the PC to boot normally. Loss of data, files and documents during such recovery does not occur. All data is saved. The operation is reversible. You can roll back the system to a previous computer state and use a different restore point.

Many people wonder how to independently (manually) make a recovery point in order to select it in the future? To do this, in the same menu "Start" - "System Restore" you can create such a point yourself at any convenient and suitable moment for you. It will be saved with the current date, which you can only remember.

From the point of recovery

In computer engineering, there is such a thing as a restore point. These are saved PC parameters. As a rule, saving occurs automatically with each successful boot of the OS. Most easy way resuming Windows 7 is to use exactly this data.

Press F8 while booting your computer. This command will bring up a menu of options for starting the system. Next, you need to select the Last Known Good Configuration option.

Another method can be used. Go to the properties of the My Computer folder. Find the line System protection, by clicking on which you will open the dialog box of the same name. Click Recovery - Next. We set a key date, indicate the disks to be repaired, and confirm the actions. After restarting, the PC should work fine.

No restore points

You can fix OS problems without restore points. To do this, you need to resort to the LiveCD program. It needs to be downloaded and written to a USB flash drive with the .iso extension.
Further, all actions will take place in the BIOS. It is necessary to configure booting from a USB flash drive. To do this, in the Boot section, select USB-HDD in the First boot device line.

Before proceeding directly to the recovery, copy all required files to a removable disk. The LiveCD program provides a special menu for this purpose.

We will fix system error using an archive copy. Connect the USB flash drive, open the Windows \ System32 \ config \ folder. Files with the names default, sam, security, software, system must be moved to any other folder. In their place, we transfer similar files from the RegBack folder and restart the computer.

The described method will only help if the problem is related to the registry.

Command line

You can resort to "reanimating" Windows 7 from the command line if the PC starts to freeze or work slowly, however, the system boots. Enter the menu "Start" and use the right mouse button to run Command Prompt as administrator. Issue the rstrui.exe command to open System Restore. Click on "Further"... In the next window, select the desired rollback point and click again "Further"... Upon completion of the process, the PC should work normally.

You can enter the utility in a different way. Go to "Start"... To call the command line, press "Run" and prescribe CMD command... We click on the found CMD.exe file and wait for the launch. Next, we enter into command line rstrui.exe and confirm the action with the Enter key on the keyboard.

It is not always possible to play it safe and create OS restore points in advance. There may be problems that block the option of such a "resuscitation" of the PC. Then you can use another, no less effective and easy option - restore the Windows system using the system itself.

We rely on the diagram:

Icon "My computer"- right mouse button "Properties";
"System protection";
In the new window, click "System protection", restore button;
"Further";
We select a restore point in accordance with the date;
We indicate the recoverable system disks;
We confirm the operations and reboot the system.

Restoring Windows 7 with Safe Mode

This method is preferred if the usual system boot is impossible. Then after pressing the power button of the PC on the system unit, hold down the F8 key to call Launch menu... One of the "Menu" options is "Safe mode"... Select it and press Enter on your keyboard. As soon as Windows boots up, we perform the same algorithm of actions that we described earlier.

System Restore Windows 8 / 8.1

If you were able to start the OS, you can resume Windows 8 via "Parameters"... Hover over right top corner and enter them. Click on "Changing computer settings" – ... Chapter "Recovery" will offer several options:

"Normal recovery with preservation of information".
"Removing data and reinstalling the OS".
"Special Option".

Decide what exactly needs to be done. Then follow the prompts on the menu.

If you choose last way, in the window that opens, click on the diagnostic item. You will be offered the following options:

"Restore";
"Return to original state";
"Extra options"... This item includes the ability to roll back to the desired resume point.

To resume Windows 8.1 press Win + R and call sysdm.cpl. In the system properties window in the tab "Protection" specify the required system drive. Click on "Restore"... By clicking "Further", you will be able to see a list of rollback points. Select the one you want and click Find Affected Programs... Changes that have been made on the PC since the selected moment will be deleted. End the process by clicking "Ready".

In the case of working with Windows 8, problems may occur, incorrect operation of the Internet, etc. To fix this, you can use the classic recovery method via restore points.

Another option is to roll back the system. To do this, open the menu "Start" - "Control Panel" - "Centre Windows updates» ... Selecting an item "Removing updates"... You can do the same using the command line.

So, in the list of updates that opens, we delete those of them, from the moment of installation of which (we look at the date) problems and malfunctions began. Delete unnecessary files and do a reboot.

In Windows 8.1, you can perform a factory reset. Important files will not be affected by this operation. The method is effective, but for its implementation you need the OS to boot without problems. We use the algorithm:

Right side of the monitor - "Parameters";
"Change settings";
"Update and recovery" - "Recovery";
"Recover without deleting files".

If you cannot log into the system in the usual way, you must use the disk with the system. We load the installation disk, select "System Restore"... Push the button "Diagnostics", and "Restore".

Windows 10 System Restore

If you're having problems with Windows 10, press Windows + Pause. Go to "System protection" and press "Restore" – "Further"... Select the required metric and press again "Further"... When done, press "Ready"... The computer will automatically restart and the changes will take effect.

One of the advantages of the "ten" is the ability to return the settings to the factory defaults. This avoids having to install the system first. To reset data go to "Computer settings" – Update and Security – "Recovery" – "Reset the computer to its original state"... Click on "To begin".

You can take care of the possibility of rollback in case of failure in advance. You can create resume points yourself, or you can set up their automatic creation at the desired frequency. To do this, in the settings, in the Update and security item, select Backup service. Specify where to save the copies, click Add Disk. After selecting a device, the function will be activated.

You can restore the Windows 10 system again through the use of restore points. In this case, the system will roll back to the moment when it booted without hindrance and worked without interruptions. This method recovery is described at the beginning of the article.

If the OS does not boot, then a warning table appears on the screen with the key "Additional recovery options"... Click it and select "Diagnostics" - "System Restore"... Making a choice control point Windows recovery, we are waiting for the system rollback and reboot.

If such operations did not help and the computer continues to work incorrectly, you can roll back to basic settings... Some programs and utilities, personal PC settings will be reset, and personal data will be deleted.

This technique is used extremely rarely if the other options described above do not help. The algorithm of actions in this case is as follows:

"Start" - "Parameter selection"- tab "Updates and Security";
Paragraph "Recovery"- button "To begin";
We choose to delete all files or keep them partially.

It will then take 40-90 minutes to roll back the system.

Resume using the installation disc

One of the radical methods of fixing the error involves using an installation disc. After launching it in BIOS, click System Restore. In the Troubleshooting section, indicate the desired action. Then follow the prompts of the system to complete the process.

Windows 7 boot stages

First stage - OSLoader

Immediately after the execution of the "BIOS" code, the first stage of loading begins. Here, at the first stage, the main drivers are connected, which are required to read data from the hard drive. After that, "winload.exe" starts loading the kernel, loads the "SYSTEM" registry hive into RAM, as well as the "BOOT_START" program.

The duration of the first stage is no more than three seconds. It ends when the Windows 7 logo is displayed on the monitor.

Second stage - MainPathBoot

MainPathBoot is the main and long-term stage. The duration sometimes reaches several minutes. The stage starts with displaying the Windows 7 logo on the monitor and ends when the desktop starts up.

Stage PreSMSS

The operating system kernel is determined, "plug and play" is loaded, the "BOOT_START" programs and drivers of the computer components are determined. If errors appear, this indicates a problem with the computer components.

Stage SMSSInit

Then control passes to "SMSS.exe". The remaining hives of the registry are determined and included in the work of the program of the "auto" type. At the final stage, "Winlogon.exe", the utility for logging into the operating system, takes control. “SMSSInit” is completed when the menu with user name and password is displayed on the monitor.

Errors here indicate a malfunction of the video card or its drivers.

WinLogonInit stage

It starts with the launch of "Winlogon.exe" and ends with the appearance of the desktop by loading "Explorer.exe". Includes exercise scripts group policies and loading services. This is the most time consuming step for the processor and usually takes a long time.

Errors here indicate problems with the services of programs not included in Windows, for example, antivirus software.

ExplorerInit stage

Continues from loading the shell and ends with loading the window manager. During the stage, shortcuts begin to be displayed, in parallel loading in progress programs that are in startup. This stage is characterized by the highest load on the processor, hard drive and RAM.

Errors here indicate defects in components or the need to upgrade them.

Third stage - PostBoot

Lasts from the moment the desktop is displayed and ends with the full opening of programs from startup.

Errors indicate problems with applications that appear in the startup list or the presence of infected files on the computer.

Errors during the startup phases

Having considered what errors occur at various stages of system startup, it is possible to identify specific problems.

Errors due to defects in computer components:

Repeated errors of any driver indicate a hardware defect associated with this program;
Multiple malfunctions at various stages indicate a defect in RAM;
If there is no image on the computer monitor, but there are sounds windows then it speaks about incorrect work video devices;
If it is impossible to start start windows or if it is interrupted, you should check the health of the hard drive;
If there is a complete shutdown at startup, then the power supply unit or the motherboard may have failed.

Missing or defective boot files

"Bootmgr is missing" flashing on the monitor indicates the absence or malfunction of the boot files, and sometimes there is just a blank black screen.

If there is no “Bootmgr” loader in the computer, the system will not boot. This section is sometimes accidentally erased by the user himself, using the boot disk.

Also, the necessary files to start the system are located on the C: drive in the Windows folder.

Registry problems

Windows can sometimes restore it on its own using the recovery wizard.

Restoring the startup of the operating system

Windows 7 has " Windows Recovery Tools WRT ". To recover, you need to select from the F8 menu "Computer troubleshooting".

Next, the "System Recovery Options" menu will appear - you need to select "Startup Repair".

This will restore the startup parameters and files.

Recovery methods

In case of a programmatic error, the "System Restore" will help the operating system.

Manual recovery

In the absence positive result after using the system tools, it is possible to manually restore the registry from a backup, which is located at C: in the WindowsSystem32configregback directory. It is necessary to copy the files from it to the WindowsSystem32config directory.

File recovery

Exists useful program"Sfc.exe", which you can run in the recovery environment. You must specify the following: parameters and location of the download folder and the offline system directory Windows directory). The / offbootdir and / offwindir options.

If the problems with the launch have not been eliminated, then you need to manually restore the boot files.

One of the worst troubles that can happen to your computer or laptop with installed windows 7 windows 8 windows 8.1 or windows 10 - failed to boot. Then be sure to run Startup Repair.

It's good if you have a saved restore point, then you can often start your computer or laptop in safe mode and roll back.

But if windows 7 does not start, then startup recovery in this way most often can be done, moreover, windows 7 starts startup recovery on its own.

With windows 10, this option will not work. In it, restore points and even safe mode are disabled by default, and no one turns them on on their own and does not even suspect about it.

Very often, startup recovery when booting windows 7 can go on for a very long time, we can say constantly ad infinitum and there will be no result. If the work is in a hurry, then panic and hassle are everywhere for a long time.

What to do if the automatic tool does not solve the startup error problem, and endless recovery is only annoying. Can BIOS help? Maybe if there is no flash drive? These questions are answered below.

How to restore startup when windows 7 crashes

So, you turn on your windows 7 computer or laptop, and they do not boot. Usually after that it starts to run automatic recovery launches and spins ad infinitum.

This is because the system looks for a restore point, but does not find it, and all the time tries to try again. Turn off. None of this will work if it didn't work the first time.

To fix the problem, you already have an installation disk, which of course you do not have. If it's not night and you have high speed internet, then the situation is fixable.

Download the windows 7 OS on the Internet, only of the bit that is installed on you. Damn, this is a nuisance I hadn't thought of. How to download if the computer or laptop does not start.

Yes, if there is only one PC and there is no way to download it, you need to go to your friends, otherwise there is no way. Let's count - downloaded. Next, you need a disk or flash drive to burn the downloaded Windows 7.

How to write down, I will not describe hundreds of instructions online, including video. If everything is ready, change the BIOS settings to boot from a USB flash drive or disk and proceed with the installation.

During installation, we reach the place when you see the system restore. Figure below.

Click on it. The system will search and find your OS

Now, as you can see in the figure below, select startup recovery and wait for the system to restore it.

This the best way way out of such a critical situation. And what to do if there is no OS disk.

Another option to restore startup

If there is no disc with the recorded OS, but perhaps you have a friend who has a computer or laptop running on windows 7 of the same bit depth as you.

Then go to him, buy a clean one on the way DVD disc and after using a friend's PC, make a recovery disc.

I will also not describe how, otherwise the book will turn out. You will find it on the net. After that, when you come home, you can restore the startup of your PC.

Restoring startup on windows 10

On windows 10, the option described above is also suitable, but do not rush. Although Safe Mode is disabled by default, you can still enable it.

To do this, you will need to shutdown your laptop or computer three times in a row.

As soon as you see the logo, immediately forcibly turn off, you can even turn off the power if it does not work with the buttons.

For the fourth time, you should see a screen with different boot options. Only here again there is a discrepancy.

In version 10, the automatic creation of restore points is disabled, and you naturally did not enable it yourself.

Then you have only one option left. Start your PC in safe mode and try to fix the errors manually.

Remember what was last installed and uninstalled. You can also use error-correcting programs. In short, fix problems.

There is another option. This is the use of a life cd disk. In this case, you will have the opportunity to edit the registry, and this can only be done by users who understand what they are doing.

It is easy to find descriptions on the net how to do this. I will not touch on them here, and so I almost wrote a brochure. Good luck.
