Why Windows Search stopped working. The computer turns on, but the operating system does not start: possible causes and solutions to the problem Problems with access to the NTLDR file

We will fix errors in Windows 10. But approximately the same will have to be done in Windows XP, 7 and 8. In Windows 7 and later, the developers have improved the recovery system after problems with startup. In older versions of the system, serious errors often have to be resolved by reinstalling.

Disconnect peripherals

Try to remember what changes you recently made to the system: whether you installed new ones, devices, or switched something. There might be a problem with one of the hardware components. Try to disable:

USB sticks.
Card readers.
Printers.
Scanners.
Cameras.
All other external devices.

If this does not help, disconnect the keyboard and mouse: all possible sources of malfunction must be ruled out.

It can also be caused by internal components such as RAM. In a desktop PC, you can check the operability of the RAM by connecting the strips one by one.

Check power

If the computer does not turn on at all, take a look at the power cord and outlets. Don't forget the power switch on the back of your desktop computer case.

If everything works at this level, but the computer still does not turn on, then most likely the problem is in the power supply, which you are unlikely to be able to fix yourself: you will have to be replaced or repaired by a specialist.

It is possible that the computer turns on, but only for a short time. This is the same problem with the power supply.

Configure the disk to boot the system

At startup, errors may appear: An operating system wasn’t found. Try disconnecting any drives that don’t contain an operating system. Press Ctrl + Alt + Del to restart or Boot failure. Reboot and Select Proper Boot device or Insert Boot Media in selected Boot device.

The BIOS or UEFI settings can be set to boot from an external device or other logical partition, and not from the system drive. You can restore the default parameters like this:

To restart a computer.
Immediately after restarting, press the system key, for example F2. It can be another key: usually during system boot it can be found at the bottom of the screen with the logo of the laptop or motherboard manufacturer.
In the settings, set the desired disk to the first place in the download.
Select the Save and Exit option to save your changes.

If the above does not help, you will have to restore the system bootloader. To do this, you will need a bootable USB flash drive or recovery disc with a suitable system for the bit depth. How to make a bootable USB flash drive or disk, read Lifehacker about installing Windows.

Start the system from a flash drive or disk by selecting the desired option in the boot menu. In the Windows installation menu that opens, select the "System Restore" item.

From the recovery menu, select Troubleshoot → Advanced options → Startup Repair. After that, the system will try to fix the bootloader automatically. In most cases, it solves the problem.

The same can be done manually through the command line, but it is better to choose the automatic option so as not to aggravate the situation.

If this method does not help, it is likely that the problem lies in the hardware: the hard drive is damaged.

From the recovery menu, select Troubleshoot → Advanced Options → Command Prompt.

In the command line, you need to enter the following commands one by one: diskpart → list volume (be sure to remember the name of the Windows disk) → exit.

To check the disk for errors and corruption, enter the command chkdsk X: / r (where X is the name of the Windows disk). The check usually takes a long time, you have to wait.

Start Windows in Safe Mode

Due to a sudden shutdown of the computer during the installation of operating system updates, cleaning from viruses and unnecessary entries in the registry, or due to the fault of utilities to speed up Windows, system files may be damaged. In this case, when the system boots, a "blue screen of death" will appear.

Try starting Windows in Safe Mode without loading any drivers or programs in Auto Startup. If the computer works in this mode, you will have to remove the drivers, roll back the system and scan for viruses.

If you have restore points, this problem is easy to fix. You just need to roll back to the previous stable configuration.

Reinstall system files

The above steps may not help. Then you have to reset Windows settings and reinstall the system while saving the files. Unfortunately, all programs will need to be reinstalled.

In the recovery environment, select Troubleshoot → Reset this PC → Keep my files → Reset.

The system will roll back to the original settings.

If a user has a problem when Windows 7 does not start on a computer or laptop, then this article will help solve this difficult task. Running Windows 7 is sometimes impossible due to errors occurring in the system after hardware problems, improperly installed software, malicious utilities, etc.

But the most common reason why windows 7 sometimes does not load is in the operating system itself.

Solution

In the case when all the initial stages of launching Windows 7 in a PC or laptop are performed normally, but still Windows 7 does not start to the end, then usually novice users are confused. Although with detailed instructions, the question is: "What to do?" not even for beginners. If the cause of the problem is a hardware failure, then it will be indicated by the beep of the speaker of the laptop or desktop computer during the POST test. If so, the OS will fail to start.

But if the problem is of a software nature and the process stops at the stage of loading Windows 7, it means that the user is faced with the most common problem that can be solved using the algorithm of typical actions.

Instructions for action

You must use an OS recovery tool. During the PC startup process, if windows 7 does not start, the system often advises the owner of the computer or laptop to choose boot options. If for some reason such a proposal has not been received, then the user can independently open this menu by clicking on the "F8" button. Then proceed to the "Sevens".

What if the above instructions did not solve the problem?

To fix the problem when windows 7 does not start, you need to use the OS CD:

Install the installation disc into the PC drive;
Start the system from the disk (in the BIOS, the corresponding order of loading the system from the media is set);
In the window that appears, click on "Apply recovery functions that fix problems with loading the OS" and click on "Next";
Then, in the "OS Recovery Options" menu, click on "Startup Recovery";
Wait until the system analysis is complete and the causes of the failures are eliminated;
Restart your PC;
In BIOS, set the system to start from the hard disk ( when exiting the BIOS, be sure to save the adjustments made);
Restart the computer again;
Ready! Windows 7 will now boot normally.

Using the command line

If for some reason it was not possible to restore Windows using the installation disc, then there is another way to do this through the command line.

First, you need to do the steps indicated in the paragraph on restoring the normal load of the "Seven". The only changes are that simply in the "" menu, you now need to specify the section - "Command line".

What to do when it was not possible to achieve a positive result by following the instructions above?

If it was not possible to achieve success and the user has already reached this part of the article, then the problem cannot be classified as typical failures of the OS bootable distribution kit. You will need to do all the further actions in Windows safe mode. It is recommended to analyze disk "C" for the appearance of broken clusters.

To enter "safe mode" you need to do the following:

Why are preventive measures important?

In Windows 7, a special system is provided that can make special reference points, with the help of which, if necessary, it is restored. By applying this protection function, even a novice user always manages to easily return the OS to a working state.

For example, in case of failures due to incorrect installation of applications, drivers and other utilities like codecs, or when errors appear due to changes in the registry.

It should be noted that the "Seven" has the ability to allocate a fixed amount of memory on the hard drive specifically for such protection of the operating system. In Windows 7, the implementation of self-configuration of protection along with system data is also available for files, or you can do it separately.

The version of the Windows 10 system has many additional features, including a convenient line search located on the taskbar. A useful option that many users got used to very quickly - with its help you can very quickly find the desired file right in the search engine on. However, some may experience Problems with her work, or she may refuse to work at all for some reason.

Most often this can happen after the next system renewal, or after installing "Tens" using the author's assembly.

You can, of course, try to restore the system using a restore point and this method will be the most effective, but not everyone creates these points, therefore, before applying such a radical method, we recommend trying the ways to solve the problem, discussed below. We will also touch upon the version of the Windows 7 system, where similar problems are also possible.

Restarting Search Service in Windows 7

If you have a Seven, the solution to the problem may be restart service responsible for searching the system.

We follow the path Start/ Control Panel/ Administration/ Services... Here in the list we find Windows Search- we press Properties.

If the service is disabled, click Run... In this case, the startup type must be set Automatically... If the service is running, try stopping and starting again.

After launching, we check the work of the search function.

Rebuilding indexes in Windows 7, 10

An effective method of fixing such a failure and for 7 and 10 versions of Windows can be rebuilding indexes... The same recommendation for fixing this bug is given by Microsoft. To do this, we find the item B.

In the Options window, open Additionally.

We press Rebuild In chapter Troubleshooting, after which we confirm this action.

Alternatively, in the indexing parameters window, click the link when searching and indexing.

The troubleshooting procedure will begin.

Upon completion, you will be prompted to select options for the problems noticed. Select the first two among them by ticking the boxes and click Next.

After diagnostics and correction, if successful, you will receive a corresponding message about the successful completion of the automatic error correction. Reboot computer - the problem should be fixed.

Using Registry Editor on Windows 10

You can try to solve the problem with editing registry keys (parameters). We start the system registry editor, for example, by entering the word regedit in the window Execute called by the Win + R key combination.

Using the explorer (presented in the form of a tree structure, similar to the standard system explorer), we are looking for the branch Windows Search on the way: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft

In the working window on the right, I am interested in the parameter called SetupCompletedSuccesfuly, it should be set to 1 .

Operating systems of the Windows family are not always highly reliable, so the developers provided the opportunity to restore the operating system from a special interface. The System Restore function is not a reinstallation, user files are practically not affected, only certain settings and system files that led to the error are reset.

However, what if this feature does not work? Is it possible in this case to restore the operability of the operating system or not?

Reasons why System Restore is not working

In total, there are several reasons that prevent you from using this OS function:

Absence Recovery points... The operating system is created special Recovery points, with the help of which the process of "resuscitation" is carried out. However, in the OS settings, the function of creating such "points" can be disabled, and if they are not there, then there is nothing to restore from. Fortunately, their absence is not a "judgment";
Broken "Recovery point"... If "Recovery point" was successfully created, but the system cannot use it and gives an error, then this means that the information stored in it has been corrupted. In this case, you will have to use other "points", if any;
Specialized software activities. Antivirus programs, special blockers, and even some optimizers running in the background can prevent the recovery procedure from starting;
There are viruses on the computer. Again, some viruses can prevent the recovery process from starting. This can be done by modifying the registry, system files, and simply deleting "Recovery points";
Serious operating system error. If some fatal error occurred while using the OS, during which the main system files were damaged or destroyed, then Recovery will not be able to start. In this case, all that remains is to reinstall the operating system;
Hardware problems. Most often, users cannot start the recovery procedure due to a breakdown of the hard disk and / or RAM sticks. In this case, they will have to be repaired or replaced, and then try to "revive" the operating system again.

Let's take a look at how to deal with several of these problems.

Option 1: Choose a different "Recovery Point"

In case you have enabled it is possible to create "Recovery points" then you will most likely be able to use more than one. So, let's look at how to perform a system restore under the following condition:

Go to "Control Panel" and find the element there "Recovery"... For ease of search, put opposite "View" meaning "Large icons" or "Small icons"... You can also use the search bar located in the upper right part of the window.
Select option "Start System Restore".

If you don't have any "Recovery points" then an error will appear. Provided that they are available, you will see a welcome window, which contains a brief description of this feature in Windows. Click on "Further".

Here you will be asked to choose one of "Recovery points" located on the computer. If there is only one "point" and after selecting it the computer gives an error, then this option will not work for you. If there are several of them, then choose any that suits you. Additionally, each "point" is sorted by date.

If you initially came across a broken "Point of Recovery" then you can choose another one. Provided that it is "intact" you will be transferred to a window where you will need to confirm your intention to restore the system.

Option 2: Disable antivirus software

Antiviruses running in the background can sometimes prevent system recovery from starting (this does not apply to Windows Defender). To avoid all problems, it is simply recommended to disable them while the recovery is in progress. This may require an additional restart of the computer.

So, let's look at how to disable the most common antiviruses. Let's start with Kaspersky (the instructions are universal for all versions):

Now let's move on to Dr. Web:

We will also consider how to disable protection from Avast antivirus:

The recovery process is done in the same way as in the first option. When finished, turn on antivirus protection again.

Option 3: Recover from Safe Mode

Sometimes, unwanted software can interfere with the activity of built-in functions in the system. In this case, you will have to do all the important manipulations from "Safe Mode"... It disables all secondary and extraneous services, drivers, etc., which allows for minimal third-party software interference with Windows.

Let's consider how to enter for most Windows operating systems:

Additionally, if in the menu after pressing the key F8 there was an option Load Last Known Good Configuration then use it initially. This is something like an accelerated analog System Restore... If the computer can boot with the last known good configuration, then most likely you will not need to perform the recovery procedure.

Users of newer versions of Windows may encounter the problem that the F8 key does not work and the menu does not appear. In this case, you will have to do the following:

Try to log into the operating system. If this is not possible, then you will have to use the instructions described in option 4.
After starting the OS, right-click on the shutdown button in the menu "Start" hold down Shift.
Without releasing the key Shift select an option.

The computer will restart and you will see a blue window with a choice of actions. Go to section "Diagnostics".

Then in "Extra options".

Now click on Boot options.

A list of hotkeys used to load any system function will appear. In your case, you need to click on F4.

V "Safe Mode" it is also recommended to disable any antivirus programs that might interfere with your work. More details on how to do this are written in the 2nd version. The operating system recovery process does not differ from that described in the first option.

Option 4: Recover from an image

If it turns out that there are no "restore points" on your computer at all, then you can use the operating system image written to the USB flash drive. Accordingly, you will need an image of exactly the same OS that is currently installed on the computer.

So, when everything is ready, then proceed to the recovery process:

Insert the flash drive with the recorded image and restart your computer.
Most likely, you will initially have to configure the boot from a USB flash drive, that is, carry out some manipulations in the BIOS. To enter it, press the keys from F2 before F12(you can also press Delete) before the Windows logo appears. The specific key to enter the BIOS can be found in the documentation for your computer and / or motherboard.
BIOS versions may differ on different computers, therefore, the interface and the layout of the elements will differ. Look for items with a name "Boot", "Advancet".
Select option "1st Boot Device"... Click on Enter to make changes to it.

A window will pop up where you will need to select the media from which the computer will boot. Choose your USB stick.
Save changes and exit BIOS using the key F10.
A reboot will occur. A window will appear where you need to select the language and keyboard layout. After press "Further".

In the next window, click on the text link "System Restore"... It is located in the lower left corner.

A window with a choice of additional actions will appear. Here you need to go to "Diagnostics" and from there to "Extra options".

Select an item "System Restore".
A welcome window will open. In it, click "Further".

System recovery will begin. Wait for it to complete.

This article covered the main reasons why System Restore in Windows might not work. Using the above options, you can restore the operating system to work.

Windows 7 has become a classic for home use, it is it that is installed on every second computer, despite the development of new operating systems from Microsoft. Having entered the market in 2009, the G7 still cannot get rid of the problems during the launch, which pretty much spoil the nerves of the multi-million user audience. To simplify the life of a user whose computer is running "seven", this article was written. In it, we will look at how to restore Windows 7 if it does not start.

BOOTMGR is missing

The most common problem that appears during the launch of the "seven".

The reasons for its appearance may be:

bad sectors of the hard disk or non-working SSD memory cells on which Windows 7 is installed (in most cases, you can restore them);
spontaneous power off or PC reboot by means of the "Reset" button;
virus activity (very rare);
inept user handling of hard disk partitioning utilities.

There are several ways to make the error disappear. We will consider how to restore a computer using the OS itself.

If you encounter problems while starting Windows 7, press F8 to bring up a menu with a list of additional parameters for starting your computer.
We select the option "Troubleshooting ...".

Choose Russian and click "Next".
We select an account with administrator rights.
We click on "Startup Repair" so that the operating system tries to find and fix the problem on its own.

If the error is not fixed, run the command line from the OS resume options window.
We enter the commands sequentially:

"Bootrec.exe / FixMbr" - writing the MBR to the system partition;

Bootrec.exe / FixBoot - Creates a boot record on the system volume.

We reboot and start the computer.

If, after performing the above steps, the PC still does not detect the installed Windows 7 during startup, run the bootrec.exe command from the command line with the "RebuildBcd" attribute.

It will scan all long-term storage devices installed on the computer for the presence of installed OS compatible with the "seven", and will add them to the download list.

And in the very last case, when nothing helps to restore the launch of the "seven", back up the old BCD folder, which is responsible for starting the PC, and create a new one. This is done using the following chain of commands:

"Disk boot failure" problem or message with text "Insert system disk"

The startup error is caused by one of several reasons, the essence of which is the following: the computer is trying to find a boot record on a disk that is not bootable. Factors preventing Windows 7 from starting:

The device from which the computer starts to boot is not a system drive - try disconnecting all flash drives, phone, camera, including external hard drives, and restarting the system.
Check the BIOS settings that are responsible for the priority of boot devices - there is a high possibility that the computer starts to boot from a disk that is not the system one. Also look in the BIOS or through one of the special utilities on which Windows 7 is installed.
Reconnect the HDD to a different cable and power cable, perhaps the problem lies in the unreliability of the connection or damage to one of the cables, for example, due to its considerable bend.

The list of reasons can be safely attributed to the lack of installed Windows 7 due to the fact that the disk with it was formatted due to the carelessness or inexperience of a novice user, and here it will help to reinstall it or restore a deleted partition.

If none of the options brought the desired result, try performing OS recovery, as described in the previous paragraph, and also make sure the hard drive is working.

Inability to start Windows due to damaged registry files

Among other things, Windows 7 may fail to boot due to corrupted registry files.

As a result, the computer will inform the user about the problem and launch an application that allows the operating system to recover.

But the tool for automatic recovery of Windows 7 is far from always effective and, for example, in the absence of a backup copy of damaged data, the user will have to manually restore the operating system.

We call a window with an extended list of startup parameters for Windows using F8.
We select "Troubleshooting ...".
Then click on the link: "System Restore".
