Windows users often encounter the problem of the "blue death screen". What is it? The fact is that damaged system files can lead to the appearance of a critical error that does not allow the computer to start correct operation. In this case, the "blue screen" appears. But do not panic! After all, you can eliminate the problem yourself. Let's figure out exactly how.
Causes of the appearance of a blue and black screen
In Windows 10, you may encounter the following error messages: "The computer is launched incorrectly", "the system requires recovery," etc. The reason for their appearance lies in the damaged system files, due to which Windows could not boot.
The system may be damaged due to the incorrect actions of the user itself, which made changes to the registry or disk files of C. or the cause of the breakage can be a virus. Error also sometimes occurs due to incompatibility with third-party drivers or activated fast loading. However, most often the critical error appears due to the interrupted update or incorrectly off the computer. For example, the computer completed the work forcibly, as the power was gone or the voltage jump occurred. The processes and files regulated by them are broken, after which the re-using them becomes impossible.
In case of damage, the system first tries to recover on its own, restarting the computer every time. If after this error is not eliminated, the control is provided to the user. Sometimes it also happens that the system freezes and reboots a large number of times, after which a black screen appears. In this situation, it is necessary to interrupt the procedure and continue the restoration manually.

Automatic system restoration
First, give the computer the ability to independently understand the error. Keep in mind that the automatic recovery procedure can go for more than an hour. In no case are not interrupting it, as this can lead to even more tragic consequences. Go to manual recovery only if the system hung or one of the messages appeared: "The computer is launched incorrectly," it seems, Windows boot incorrectly. "
The appearance of the "blue screen of death" indicates the presence of a critical error in the system
Reboot
This method will suit you if the system issued a message with a choice of two options: "Restart" and "Advanced Parameters". If it is not, you will have to take advantage of other ways.
What should be done:
- After receiving a notification, go to the "Advanced Settings" section.
Start the recovery of the system by turning to additional parameters
- Select the troubleshooting unit.
Open the "Search and Fault Correction" tab
- Select a section with additional parameters.
Select "Advanced Parameters"
- Go to the Download Options tab.
Open the Download Settings section
- In the list that opens, click "Restart".
Click "Restart"
- A list with download parameters will open. Select the 6th option - the command line support mode. Wait until the system restarts and the command line will appear.
Select a reboot with command line support
- In the command prompt, execute three commands sequentially:
- sFC / SCANNOW;
- dISM / ONLINE / CLEANUP-IMAGE / RESTOREHEALTH;
- shutdown -r.
Execution of commands takes time wait for their completion

Deactivation of quick launch
The reason for the impossibility of recovery can be a quick load activated by default. Since in this case there is no access to the system, you will have to deactivate the function via BIOS:
If this method has not worked, go to the next.
Deactivation of automatic recovery
It happens that the system resorts to restoration without reasonable causes by mistake. Therefore, it is worth trying to prohibit it calling the recovery procedure by following these steps:
- When the message appears, go to the optional parameters and call the command line.
In the "Advanced Settings" menu, open the command prompt.
- Using the bcdedit command, find the ResumeObject string and copy its value.
Run the bcdedit command to go to the Windows Download Manager
- Run the bcdedit / set (x) recoveryenabled command, where X is a previously copied string enclosed in curly brackets. After that, exit the command prompt by the EXIT command.
Run BCDedit / Set (X) RecoveryEnabled to disable automatic recovery
Ready! Now try downloading the system.
Manual launch of diagnosis
Going to the command prompt using the method described in the "Deactivation of Automatic Recovery" or "Reboot", follow these commands:
- cHKDSK / R C:;
- sFC / SCANNOW.
Run the CHKDSK / R C; SFC / SCANNOW command
These commands scan system files and correct the errors found. After executing them, write an exit to exit the command line and check whether the problem disappeared.
Manual system restoration
If none of the described methods helped eliminate the problem, you will have to return the system to the operating state manually. There are several ways to make it.
Point of recovery
This method is good because your data (photos, music, archives and other files) will not be deleted or changed. System settings, updates and driver versions roll up to the state in which they were at the time of creating a recovery point. If it was not automatically created or manually in advance, then use the method will not succeed.
Perform the following steps:
After that, the procedure for rollback will begin, which can last about an hour. Do not interrupt it - it will lead to big problems. As a result of rollback, system files are regenerated, so that errors should not occur.
Reset to factory settings
This method allows you to reset all system settings, installed programs and created tasks, and at the same time save the user's personal data stored in the system section. This method replaces the reinstalling system, allowing you to accomplish it much faster.
Perform the following:
A rollback procedure will start, which can last more than an hour. Do not interrupt it, otherwise the system will damn so much that direct reinstallation cannot be avoided. At one of the stages, you will ask, whether to save personal data or not. If you select the option "Do not save", you can get absolutely clean Windows 10.
Select, save your personal data or not
Manual entry in the recovery menu
For manual login, the recovery menu will require a recovery medium. The installation flash card that has at least 8 GB of memory will be used as it.
To create an installation media, follow the instructions:
- Insert the flash card into the working computer, find its icon in the explorer, click on it right key and select the "Format" function. Call, create a media in any version of Windows, but the format function is present only in Windows 10. In previous systems, you will have to use a third-party program, such as USB Disk Storage Format Tool. Formatting format - FAT32.
Before forming a flash card, select Fat32 file system format.
- After the format is completed, go to the Microsoft website to the Windows download page and download the installation program.
Go to the Microsoft website and download the system installer
- Run the downloaded program. Note that you want to update another device.
Select "Create installation media"
- When you are asked to choose the characteristics of the recorded system, specify that the data that coincides with the characteristic system in need of restoration.
Specify the characteristics of the system you want to restore
- Specify which media is worth using, and wait for the record. Ready, installation media created.
Specify the media - flash card or disk
- After the operation is completed, run the flash card on the non-working computer. To do this, log in to the BIOS (how to do this, described in the first step of the "Deactivation of Quick Start") and change the load order so that the connected media dismissed the hard disk from the first place.
Set the installation media for first place.
- Exit BIOS and wait for the installation window appears. Go through the first step of selecting the language, and on the second interrupt the installation procedure by pressing the "system restoration".
Click "System Restore" in the second step of installing Windows
By completing these actions, you will find yourself in the recovery menu and you can use all the instructions described above.
System image generation
If you have another computer with the same features of Windows 10, as the non-working computer, you can write the image image. Thus, you will create a recovery point and you can use the above-described Windows error correction method using the recovery point.
To generate a system image, do these steps:
- In the Control Panel menu, go to the "File Story" section.
Specify the media to which the system image will be recorded.
The appearance of a blue or black screen with an error informs the presence of a collection or damaged files in the system. You can fix the problem using the automatic system restore parameters. If it does not work, use one of the methods of manual recovery. Follow the instructions from the article and you will definitely work out!
Although the Windows 10 operating system is constantly improved and grind, it still contains a greater number of errors than in previous versions. For example, the user may encounter a problem when loading the operating system: "Preparing Automatic Repair" appears on the boot screen, but no restoration occurs, and Windows 10 does not start. What to do in this case, read within this article.
About the error
Preparing Automatic Repair (automatic recovery preparation) occurs if for some reason Windows 10 is damaged. In fact, the "Preparation" function should restore damaged files from the saved recovery points or Windows installation files on the connected external media. But for the absence of such a window simply freezes and after a while, a reboot occurs. And the cycle is repeated anew, turning into a closed loop. Run the loop by turning off the power on time and read the correction instructions.
How to fix?
There are several effective advice to eliminate this problem.
Enabling XD-BIT in BIOS
Until the XD-BIT function (also known as No-Execute Memory Protect) is turned off in the BIOS settings (UEFI), the user faces the PREPARING Automatic Repair loop.
Interesting to know! The NO-EXECUTE Memory Protect feature provides additional protection against hacker attacks, viruses and similar hardware threats (hardware support for the execution of program code execution from the data area). For the first time, a similar function was acquired in processors: AMD Athlon 64, SEMPRON on their database, Intel Pentium 4 latest modification and Celeron on their base.
An increase in the section "Reserved by the system"
An error may occur due to the section "Reserved by the system" in which there is less space than it should be (you need at least 250 MB). To increase the location of the section, use the MINITOOL PARTITION WIZARD boot utility. You may need another computer or:
- Download the utility (ISO file).
- Mount it to a virtual disk (PCM on the file → Open with → Explorer).
- Connect the FAT32 formatted USB flash drive, open the virtual disk and drag files to the flash drive to record.
- Also, to record the utility on a flash drive from the image, you can use any convenient program ,.
- Restart the computer and boot from the flash drive (this will help with this).
- An open program will allow working with hard drives.
Right-click on the "C:" system disk and click "Shrink". Check the area of \u200b\u200b250 MB. A 250 MB of non-placed area will be created. - Move the System Reserved section next to the undivided area (Unallocated Space). Then click on the SYSTEM Reserved PCM and execute the Extend function (alignment of the inseparable area with volume is reserved by the system).
- Restart the computer and check the Windows.
System Restore
You can restore Windows 10 using the boot disk or flash drive with a Windows distribution:
Reinstalling Windows
If not one of the tips described above did not help run Windows, reinstall it with
Running automatic recovery
Start automatic recovery from the recovery disk is very simple. After downloading the system from the disk, go to the section "Diagnostics | Additional parameters "(Troubleshoot | Advanced Options). A screen will open with a list of additional parameters (Fig. A), including automatic recovery.
Figure A. On the Advanced Settings screen, four Windows Recovery Tool are presented.
When the automatic recovery is selected, the screen shown in Figure opens. B.
Figure B. Automatic recovery - the first tool to which you should resort if Windows 8 does not start.
At startup, the automatic recovery tool immediately starts searching for errors (Fig. C).
Figure C. At the first stage, the automatic recovery tool searches for errors.
During the diagnostics process, the utility scans the system, analyzes the settings, configuration parameters and system files in search of errors and damage. The following problems are searched for:
Missing / damaged / incompatible drivers;
missing / damaged system files;
missing / damaged bootloader settings;
damaged registry settings;
damaged disk metadata (main boot record, partition table, boot sector);
incorrectly installed updates.
If any of the listed problems, the utility tries to automatically fix them (Fig. D).
Figure D. Finding the problem, the automatic recovery means is trying to fix them.
If the utility can fix errors, it will do it yourself and then reboot the system into a regular working environment.
Serious malfunctions
If the automatic recovery tool is not able to solve the problem, the screen appears shown in Fig. E. In this case, the utility creates a log where it records detailed information, and offers to return to the additional parameters menu where you can select another tool for diagnostics and recovery.
Figure E. If the automatic recovery tool is not able to solve the problem, this screen opens.
Before using other utilities, you should familiarize yourself with the magazine. On the recovery disk there is notepad (NotePad), which can be used to view. To do this, remember the path to the log file and its name. On the "Advanced Settings" screen, select the Command Prompt (Command Prompt).
In the command line window, enter the letter of the disk on which the log file is stored (in my case it is "D"). Then use the CD command to go to the file folder. After that, enter the name of the notepad executable file and the log file name.
In my example, the set of commands looks like this (Fig. F).
D: CD \\ Windows \\ System32 \\ LogFiles \\ SRT NotePad.exe SRTTRAIL.TXT
Figure F. From the command line you can run a notepad to view the log file.
In the notepad, you can see the contents of the file "SRTTRAIL.TXT" (Fig. G). At the end of the magazine, it will certainly be found information about some unsuccessful test, which is useful for further diagnostics.
Figure G. Information in the SRTTRAIL log may be useful for further diagnostics.
If the recovery disk is created on a flash drive, you can save the notepad file directly to it, connect a flash drive to another computer and print the log so that the information needs is at hand. Then do not forget to return the recovery disk back to the problematic computer.
If the recovery disk is created on an optical medium, the file cannot be printed, so you have to write useful information manually.
Docted automatic recovery
Recently, my buddy faced the fact that his laptop running Windows 8 was stuck on automatic recovery: the system was restored, rebooted, started recovery, and so in a circle. Running a laptop from a USB recovery disk, we decided to try a few bootrec teams on the command line, which at one time helped us repair seriously damaged Windows 7.
In our case, the use of BootRec in combination with CHKDSK worked. Other computers with Windows 8 suffering from similar problems, I have not found, so I can not say how reliable this method. Nevertheless, I heard that other users were able to solve their problems with it. So you can try before you take for other recovery tools.
In the command prompt window, follow the following commands one after another:
BootRec / FixMBr BootRec / FixBoot BootRec / RebuildBCD CHKDSK / R
Switch / FixMbr. writes on the system section a new main boot record (MBR), / FixBoot - new boot sector, and / RebuildBCD. Scans all the disks for the presence of Windows installations and offers to add them to the download configuration data (BCD). Team Chkdsk. with switch / R. Looking for damaged sectors on disk and restores data that can be read.
After the CHKDSK is completed, turn off the recovery disc and restart the computer.
What do you think?
Have you had to use the function of automatic restoration of the system in
Automatic recovery when booting Windows 8/10 sample description.
Startup Repair. or Automatic Repair.- This is the same recovery utility WindowsBut in different ways named according to Windows version. Thus, in Windows Vista and Windows 7, it is called " Startup Repair.", And in Windows 8, it is called" Automatic Repair.", And in Windows 10, it is called again" Startup Repair.».
This article is intended for Windows 10 and Windows 8, if you need to restore Windows 7 or Vista startup,
So, now the questions we usually ask:
- What is it: restore Windows 10 startup?
Both functions are the same, and this is a very useful and efficient tool for Windows restoration. The main work of this feature is to restore Windows when something bothers the launch operating system.
- What does "restore when starting" or "automatic repair" actually makes it in Windows?
Startup. or Automatic Repair. - This is the only recovery tool that you have, since Windows that requires immediate recovery, start it. This tool is designed to restore only certain glitches, such as missing or damaged system files that were mainly used to boot the Windows operating system.
- Why "recovery when loading" or "automatic repair" writes " can't corrected«?
Indeed, this feature can not show you what creates a problem for running Windows. It will not help you restore personal files and documents. It also cannot detect or eliminate hardware failures and does not help in the fight against viral attacks and their damage.
How to use "Recovery when loading" and "Automatic repair"?
When you enable your computer, and it will display your logo screen. Bios., quickly press the " Shift.»And press the key several times. F8..
This may not work the first time. Just restart the computer and try again. In the end you will fall into the recovery mode, and you will see the next step described below.
If you can not open it with the SHIFT and F8 keys, the only way is to use it Windows Disc. or Windows USB PENDRIVE.. It will also help if Windows 7 is launched.
To open autoload or automatic repairs from a Windows disk:
Use only the boot disk corresponding to your current operating system. For example, use the Windows 8 installation disk if you installed Windows 8 to your computer. Use the Windows 10 installation disk if you use Windows 10.
First, you will need to download your disk or Windows USB flash drive using the boot sequence priority. If you do not know how to do this, click on the link below. Restore Windows 7 launch via the command line (Win 8/10):
- Immediately after the download was completed, you can see the first setup menu item, and you need to click " Further", Then click" Restore computer"To launch the recovery function when starting.
- After that you will see three options. It will be necessary to choose the second, called " Troubleshooting"And then directly under the troubleshooting menu, select the third parameter" Additional parameters».
The article is dedicated to messages that appear on the Automatic Recovery screen and inform the user that the operating system started incorrectly or the computer is launched incorrectly Windows 10. In the article we will deal with the reasons for their appearance and consider how to get rid of such messages and prevent them.
What should be done first
When alert appears that the PC is incorrectly loaded, you must restart the computer. In cases where the message pops up when rebooting the system due to the interrupting Windows update, it helps.
The second thing that can be the source of the problem is the abnormal mode of functioning of the power supply, as a result of which the hardware components operate in the mode differing from typical. Due to the two unsuccessful attempts to download Windows 10, the latter calls the system recovery function, thereby providing the user to solve the problem.
Perhaps the cause of the problem are drivers. Remember or look, the drivers of which components were installed last and perform their rollback.
The appearance of the message after resetting or updating Windows
A common algorithm, the execution of which leads to an error appears is the following: Turning on the PC After updating / reset Windows, is accompanied by a blue screen, and after collecting information, a window is started with the options for restoring the operating system.
- In this case, go to "Additional Parameters".
- Call "troubleshooting".
- We again go to "Additional Parameters".
- Click "Start Parameters".
- We click "Reload".
After restarting the computer, "boot parameters" will open, where, using the F6 key, run a secure mode with command line support.
Perform command sequence:
- sFC / SCANNOW - checking system files with recovery damaged;
- dISM / ONLINE / CLEANUP-IMAGE / RESTOREHEALTH;
The appearance of an error "Computer is launched incorrectly"
It happens that, due to the inclusion of the computer, an alert appears that reports on the implementation of the computer / laptop diagnostics. The latter ends with a blue screen with the text "Computer run incorrectly" and open the "Advanced Settings" recommendation after rebooting.
Specifies this situation on the damage of system files is often the registry.
The culprit of the situation is:
- power supply interruptions;
- work viruses or antivirus program;
- windows 10 updates;
- deleting or incorrect values \u200b\u200bof critical to operation of a key.
To solve the problem, we do the following.
1. Go to "Advanced Parameters".
2. Click on the "Troubleshooting" item.
3. Click on the button with the inscription "System Restore".
4. With the active function of creating rollback points, we choose one of the last snapshots of the system and click "Next", then "ready."
Often, the resumption of Windows 10 solves such a problem.
5. If the option is disabled (it should be enabled after returning the system to the operating status), a window appears where you want to select "Troubleshooting".
6. Click "Return PC to the original state", in order to reset Windows 10.
7. We definitely select an option with maintaining personal files (all on the C \\ disk: files will remain on our own places after Windows reset, but the installed programs does not concern it).
Further actions can edit the situation and exacerbate it. Their execution may lead to unexpected consequences. Following the steps below subjected the system at risk, remember this.
Using the command line, as in the past method, check the integrity of the system files, correct damaged, and also restore the registry files from the backup.
8. We execute the "diskpart" command in order to call a tool for working with sections.
9. Enter "List Volume" - a consequence of the execution of the command will be visualizing the list of volumes of all connected to the PC discs.
10. In the list we find a system disk and reserved by the system and remember their letter tags.
11. Close the program by performing "exit".
12. Enter "SFC / SCANNOW / OFFBOOTDIR \u003d F: \\ / OFFWINDIR \u003d C: \\ Windows" and click "Enter".
Here: F - reserved by the system volume or drive (with a loader), C is a system partition.
13. "C:" - go to the system disk where Windows is located
14. MD ConfigBackup - Create a CONFIGBACKUP directory.
15. "CD Windows \\ System32 \\ Config \\" - go to the appropriate folder.
16. "Copy * C: \\ ConfigBackup \\" - copy a directory previously created to it.
17. "CD Windows \\ System32 \\ CONFIG \\ REGBACK \\" - go to the RegBack system folder.
18. "Copy * C: \\ Windows \\ System32 \\ Config \\" - copy the contents of the specified directory to active.
19. Click "A" with the Latin keyboard layout and "Enter" to confirm the overwriting of the files.
These actions will restore the registry files from the automatically created backup.
20. Close the command prompt window and click on the button with the text "Continue. Exit and use Windows 10. "
With a large share of the probability of Windows 10, after performing this simple algorithm it will start.
Cases completely "kill" Windows 10 by manipulations with the registry files are extremely rare, but still happen. If this happened or the actions did not bring the desired result, one of two solutions remains:
- Reset Windows 10;
- Reinstall the operating system.
The first is done through the "Search / Troubleshooting" item in additional parameters. Even in critical situations, you can get there by using the bootable media with the Windows 10 distribution.
In the second case, you will need a loading flash drive and about 30 minutes of partially free time.
