Windows 10 automatic repair preparation won't load. Performing an operating system rollback

BIOS- a set of utilities that are installed on the motherboard, which make it possible to turn on the device to install the OS. With its help, Windows 10 is loaded, the data carrier is selected, the range of thermal sensors is indicated, and various parameters are configured. If the system stops booting, errors fly out and recovery fails in the standard way, you can use the BIOS.

How to restore windows 10 through bios.

But this method can only be used if you have an installation disk or flash drive with a distribution kit of a licensed operating system with the version and bit depth that you have installed, this option is not possible without an external drive.

First of all, you need to start by setting the BIOS to read the disk immediately when the computer starts.

If preparing automatic recovery does not make it possible to restart the computer normally, you need to do it forcibly by holding down the shutdown buttons for 10-15 seconds, as soon as the system starts to boot, you must press one of the keys: F1, F4, F3, Delete, F8 (exactly what it is you who needs to click cannot, as it depends on the model of the motherboard on your device).

In the instructions for the computer or on the manufacturer's website, you can look for which key you need to enter. On most PCs, the "Delete" button is used, on laptops, the key combination "ctrl + alt + esc" can be used.
After the BIOS starts, go to the Boot section.

You need to find the "1st boot device" parameter, which can be located in the "Boot Device Configuration", "Advanced Features", "Boot", "Boot Sequence. There you will need to set the parameter for the CDROM or PXE UND I disk to boot from a USB flash drive:


Press "F10" to save the result, insert the disk into the drive or connect the USB flash drive on which the distribution is stored, then reboot the device.

After the computer boots up, the initial system installation menu will appear, where you will need to click on the "System Restore" button.

The "Select actions" menu will open, you need to select the "Diagnostics" item.


Then go to the item "Advanced options".

Next, click on System Restore.


After clicking, a window will open with a choice of a restore point.


The Startup Repair feature scans your computer for errors and fixes them as they are found. You can try to run the utility, but in most cases, after the search, it usually displays a message that the computer could not be restored.

If you had a rollback and your Windows was successfully restored after the indicated actions, then the field of this will need to go into the BIOS and return the hard disk boot priority back to the first place.

- How to restore Windows 10 through the command line.
If you did not create a checkpoint, you can try to restore the Windows 10 system through the command line. To do this, you will also need a boot disk or USB flash drive with the Windows operating system installed on your computer.

In the "Advanced Options" section, select "Command Prompt"


In the window that opens, type "fixboot".


Then the action must be confirmed by pressing the "Y" key.
After restoring the Windows 10 bootloader, the system needs to be checked for corrupted system files.

Solutions for Corrupted System Files

1. The boot sector of the operating system is damaged.
   At the command prompt, type "fixboot", press "Enter", then type "fixmbr", press "Enter". After that, the windows boot sector will be restored. The computer can be restarted normally.
2. The boot file boot.ini is missing.
   In the line you need to type "bootcfg / rebuild", then press "Enter". All possible questions of the system are confirmed by pressing the "Y" and "Enter" keys.
3. Corrupted config in system32 folder.
   You need to insert a disk with your OS version into the drive, enter "cd repair copy SYSTEM C:\windows\system32\config" at the command line, and then press "Enter".
4. The files "ntldr" or "ntdetect.com" are missing, the system gives a message: "NTLDR is missing when loading Windows".
5. Type "copy X:\i386\ntldr C:\" in the command line, press "Enter" (Where X is the letter of your drive, and C is the letter of your system drive where your OS is installed).

System restore via command line when the computer is on.

If you do not want to restart your computer, you can restore the system through the command line from Windows. To do this, you will need to insert the disc into the DVD-ROM while the PC is booted. Then launch the command prompt by pressing the hot key combination "Win + R" and in the search row of the "Run" window, enter "sfc / scannow" and click "OK". After that, the broken distributions of the system will be copied from the boot disk automatically. System restore, rollback is quite fast and hassle-free.

Automatic Startup Repair Windows 8/10 -detailed description.

Startup Repair or Automatic Repair is the same recovery utility Windows, but named differently according to the version of Windows. 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 again called " Startup Repair».

This article is for Windows 10 and Windows 8, if you need a Windows 7 or Vista startup repair,

So now the questions we usually ask are:

• What is Windows 10 Startup Repair?

Both features are the same, and it is a very useful and efficient Windows recovery tool. The main job of this feature is to restore Windows when something prevents it from starting. operating system.

• What does "Startup Repair" or "Automatic Repair" actually do in Windows?

startup or Automatic Repair is the only recovery tool you have, since Windows that require immediate recovery will launch it. This tool is designed to repair only certain glitches, such as missing or corrupted system files, which were mainly used to boot the Windows operating system.

• Why does "Startup Repair" or "Automatic Repair" say " can't fix«?

Indeed, this function cannot show you what is causing the problem to start windows. It will not help you recover your personal files and documents. It also cannot detect or repair hardware failures and does not help in the fight against virus attacks and their damage.

How to use Startup Repair and Automatic Repair?

When you turn on your computer and it displays your logo screen BIOS, quickly press the " Shift» and press the key several times F8.

It may not work the first time. Just restart your computer and try again. You will end up in recovery mode and you will see the next step described below.

If you can't open it with the Shift and F8 keys, the only option is to use Windows Disc or Windows USB Pendrive. It will also help if windows 7 startup recovery does not start.

To open Startup or Automatic Repair from a Windows drive:

Use only a boot disk that matches your current operating system. For example, use the Windows 8 installation disc if you installed Windows 8 on your computer. Use the Windows 10 installation disc if you are using Windows 10.

First, you will need to boot your Windows disk or flash drive using boot sequence priority. If you don't know how to do it, follow the link below. restore windows 7 startup via command line (win 8/10):

• Right after the download has been completed, you will be able to see the first item of the setup menu and in that you need to click " Further", then press " Repair your computer" to start the startup repair function.

• After that you will see three options. You will need to select the second one, called " Troubleshooting", and then right under the troubleshooting menu, select the third option" Additional parameters».

If your Windows 10 suddenly stops working, don't fret - there are so many ways to fix it. For example, rolling back to a previous state, a restore checkpoint, or creating a system mirror and saving it to external media, followed by recovery via a bootable USB (this option in Ten works much better than in previous versions). Below we will look at all the existing options for restoring the Windows 10 system and find out what errors most often occur when starting it.

For successful recovery, you need to understand how this or that option works. First you should try to start Windows in . With it, you can perform a "clean" boot, without activating additional drivers and software. Failure can occur not only in Windows itself. Most likely, this is an error of the driver installed later, or some application. If safe mode does not solve the problem, you can proceed directly to recovery.

This feature has recently appeared in Windows 10 and has already managed to prove itself well. This is something similar to a hard reset on Android smartphones (Windows returns to factory settings). You can start the process in several ways:

1. Click on the notification icon and click on the "All settings" tile.

1. Click on the "Update and Security" tile.

1. In order to return Windows 10 to factory settings, click on the "Restore" entry, and on the right side - on the "Start" button.

There is another possibility to get into this menu, we will talk about it below. In the same place, we will tell you what to do if Windows 10 does not start and you cannot get into the rollback settings. Once the Start button is pressed, you will be presented with two options to reset Windows 10. You can reset the system to its original state and still keep all user data, or permanently delete everything and reinstall the OS clean.

You can get into this mode even without logging in. To do this, on the Windows login screen, hold down the Shift button and restart the PC.

A menu will appear in which we need to select the item indicated in the screenshot.

It remains to click "Reset the computer to its original state."

On the next screen, we will again be offered the choice of whether to save or delete user data.

After that, our system will go to reboot and the recovery process will begin.

We only need to wait while Windows prepares all the necessary files.

Once again, we will be prompted to choose the recovery option: we will do a “clean” reinstallation, so click “Just delete my files”.

"Ten" will notify that all data will be deleted. We agree and click on "Return to original state".

The recovery process may take a long time. Sometimes many times more than if we reinstalled the system from a flash drive. By the way, you can read about how to do this.

After clicking the "Clear" button, the installation of Windows 10 will begin.

1. Select the location we need.

1. Decide on the system language.

1. We agree with the Microsoft license and click the "Accept" button.

1. Select the type of use of the system.

1. Choose an authorization method. You can use a Microsoft account, sign up for one, or sign in to a local account.

After the process is completed, the computer will be returned to its original state. In other words, it will be as if only after the installation of the operating system. In some cases, you may need to install drivers.

The advantages of automatic system recovery include the ease of use of the tool and the absence of the need to have bootable media.

On laptops and computers that had Windows 10 preinstalled, resetting means installing all the necessary drivers (there is a special partition for storing them on the disk).

Using the recovery disk

The recovery disk is a medium that contains all the necessary data for the reincarnation or complete restoration of the OS and system files. Let's look at the algorithm for creating a Windows 10 recovery disk. Below is a step-by-step instruction with screenshots. Getting started.

1. Open the system settings using the search tool. It is located on the left side of the taskbar. Enter a name in the search field.

1. In the search bar of Windows parameters, we write the word "Disk" and in the output we select the tool we need.

1. If, when creating a disk, we check the box next to the item marked in the screenshot, in the future we can not only fix the OS, but also reinstall it again with copying all user data.

1. Select the disk to which the recovery image will be written, and click "Next".

1. Windows will notify us that all files on the flash drive will be deleted. We agree and click "Create".

1. After the preparation of automatic recovery is completed, disk creation will begin. The process may take a lot of your time.

With our recovery disc you can:

• restore the previous state of the computer from a backup;
• use the rollback mode to a restore point;
• apply automatic recovery mode at system startup;
• use command line;
• perform a full recovery of Windows 10 from an image.

The drive, the creation of which we described, is even more convenient than a simple installation flash drive. After all, using the latter, you need to configure Windows 10 every time, and the system restored from a copy requires almost no configuration and is immediately ready for use.

Rolling back the OS with a full image

The "Ten" has the ability to complete backup of the entire system. Below we will look at how to create an image and how to restore the OS from it, for example, after failures that arose due to the fact that the computer was not started correctly. Each step of the step-by-step instructions for clarity will be accompanied by a screenshot.

This option differs from the one described above in that we create a complete snapshot of the existing operating system with drivers, user files, etc. Using this image, you can restore the system and immediately proceed to use - no additional steps will be required. It is best to back up as soon as the system is installed, configured and, in general, brought to a healthy state. But in no case not when it is already starting to slow down from clutter.

Let's start creating a complete image of the existing Windows 10:

1. Open the control panel using Windows search (click the magnifying glass icon, enter a search query and click on the result).

1. In the search field of the control panel, write "File History" and click on the result.

1. Now in the lower left corner, click on the inscription indicated in the screenshot.

1. Go to "Create a system image".

1. Now you can proceed directly to creating the image. There are three options for saving it. We can burn the backup to a hard drive, split it into multiple DVDs, or specify a destination network folder. Let's use the first option. We click on "Next".

1. Let's get down to business - click on "Archive". The system tells us that this may require about 46 GB.

1. The creation of the archive has begun. Depending on the amount of data and PC performance, it may take different times.

1. When the backup is completed, you will see the following window. Click "Close".

In the future, the system can be restored from this image. To do this, when the OS is being installed from a USB flash drive or disk, select the recovery mode and specify the image created above. The system will unpack the archive to drive C and will be ready to go. This is much more convenient, if only because the OS no longer needs to be configured, drivers and software installed: you just sit down and start having fun or work.

How to create a restore point in Windows 10

Restore points in the 10th version of the OS from Microsoft work exactly the same as in versions 7 and 8. With their help, you can return the system to a specified point in its life and fix the problem that arose after the checkpoint was created. In order for us to roll back the system to a restore point, we need to enable their creation. We do the following:

1. Go to the control panel (we described how to do this in Windows 10 above). Next, in the search bar, write "Recovery" and click on the result indicated in the screenshot.

1. In the next window, click "Configure System Restore".

1. In our case, automatic creation of rollback points is disabled. Let's fix this - select "Customize".

1. Activate the automatic creation of control points and click "OK".

Now, with any change in Windows settings, restore points will be created automatically. You can also make manual dots here - this is necessary before any serious step, for example, installing a suspicious program.

When you need to apply one of the points and fix the system, go to the control panel, namely "Start System Restore", and restore the copy. If Windows does not start, you can use another option. Boot from the installation USB flash drive or disk and select the system recovery mode there.

Restoring the bootloader using the command line

Despite the fact that working with the command line is a way more designed for professionals, everyone can use it. The main thing is to follow our instructions exactly.

1. Initially, install bootable media in the PC slot and boot from it. In the window that appears, click on the item indicated in the screenshot.

1. Next, click on the tile called "Troubleshooting".

1. Select "Command Prompt".

1. Now you can run the utility to restore the master boot record. To do this, enter the command bootrec.exe C:\Windows (indicate the drive letter on which your system is installed) on the black screen and press Enter.

The system will inform us about the successful creation of disks - the master boot record has been restored.

Comment. To work correctly with operators, you need to know the name of the disks installed in the system. Such names are individual and in most cases do not match.

Registry recovery

The operating system registry is periodically saved in the directory indicated in the screenshot.

To create a copy of the registry, copy these files and save them. You can restore data by moving it back with a replacement. Naturally, for this you need to have administrator rights.

Error 0x80070091 during system restore

Users are increasingly asking: what causes error 0x80070091 when working with restore points. This is due to a system update and will be fixed in the next patch later. You won't be able to fix the error yourself.

Summing up

Now we know how to roll back Windows 10 and perform its advanced recovery. There are many options for this, and all of them are effective. When used correctly, they will be enough to fix any problem in the operation or startup of the operating system. There are additional programs that can reset Windows 10 to factory settings, such as Aomei OneKey Recovery. This can be the same Acronis or a backup image provided by the computer or laptop manufacturer. But you should not discount the tools in Windows 10 - their functionality is enough to solve any problem.

If there are serious problems that prevent Windows from booting normally, the built-in wizard usually prompts you to perform a repair. However, if the error occurs during the recovery itself, the process may become looped and the system will start the recovery on each new boot. Of course, reinstalling Windows will solve the problem, but in doing so, you will lose all installed programs. Well, if you took care of creating a full backup of the system in advance, but what if there is no such copy?

However, this is not yet a verdict. You can try to "knock" the system out of the recovery cycle using this instruction. All you need is a Windows installation disc and a little attention. With the BIOS set to boot from external media, insert the disc and boot from it. The Windows setup menu will appear.

Run the bcdedit command in the console that opens.

As a result, you will get a list of boot options. In the first block "Loading Windows" find the line resumeobject and copy the identifier opposite it.

Now run the bcdedit /set (GUID) recoveryenabled no command, replacing (GUID) with your identifier.

Thus, automatic recovery will be disabled and the cycle will be interrupted. Deactivating the recovery procedure, however, does not eliminate the errors that caused it. Therefore, it is highly desirable to check the file system by executing on the command line chkdsk /rc:.

And if this does not give positive results, you can run the command sfc /scannow aimed at restoring corrupted system files.

You can also enable the boot manager, called, as in Windows 7, by pressing F8 immediately after turning on the computer. To do this, run the bcdedit /set (default) bootmenupolicy legacy command in the running console.

If all this does not help start Windows, most likely, you will have to move on to radical options - reinstalling or resetting the system to its original state.

Have a great day!

Restoring Windows 10 allows you to return the operating system to a healthy or original state from an automatically or manually created system rollback point or a complete system image stored on a hard drive.

Also in the “dozens” toolkit are an OS reset tool that will save you from a lengthy reinstallation of Windows 10, and creating a recovery flash drive necessary to resume the operation of the operating system in critical situations (when Windows 10 does not boot and does not provide an opportunity to get into the recovery environment) .

The proposed article-instruction tells about all the tools that make up the system recovery environment in Windows 10, the mechanisms of their functioning, how to use a particular function and the effectiveness of recovery methods in certain situations.

Before proceeding with the study of the material, it is recommended that you read the instructions on restoring the operating system bootloader, checking its files for integrity, and restoring damaged registry files.

Safe mode

The first thing to try when you encounter problems is to boot into safe mode. Consider the situation when the "ten" does not boot and does not allow you to reboot with the appropriate parameters (it will not work to get into this mode through msconfig or special boot options).

1. We start from the bootable media with the Windows 10 distribution using the Boot Menu.

4. Run the command "bcdedit / set safeboot minimal" to start the computer in safe mode.

5. Reboot by closing all windows.

After starting the computer, you can work on resolving the problem that prevents the PC from starting / functioning normally.

We return the computer / laptop to its original state

The most noteworthy recovery feature that appeared in Windows 10 is the reset of Windows to its original state. You can use it through the "Settings".

1. We call the menu using Win→I.

2. Go to the "Update / Security" section.

3. Click on the "Recovery" tab.

You should use this option as a last resort when the options below did not help solve the problem, because in the end you will get a clean, just installed operating system with or without personal data, depending on the specified parameters.

4. Click "Start", after which a dialog will appear asking you to specify the parameters for resetting the operating system.

The first option is to completely clean up the system volume from all files and quickly reinstall the "dozens" without using the installation disk with the operating system distribution kit, the second way is to quickly install Windows 10 while saving user files and settings of applications installed on the PC, the programs themselves will not be saved .

There is another way to call the operating system reset dialog even without authorization in the system. Everything is done on the login screen. To access the function, click on the "Reboot" icon while holding down the Shift key. After restarting the computer, click on the "Diagnostics" icon, then click on the button to reset the system to its original state.

The advantages of the method are that there is no need to have an installation disk / flash drive and all actions are performed automatically without any intervention from the user.

There is only one drawback - if the user deletes the system image or if this file is located in damaged sectors of the hard disk, it will not be possible to perform a quick reinstallation, but here the “dozens” have several additional tools in its arsenal: using the system recovery disk if available (a very rare occurrence) and backing up Windows 10 using OS tools on a volume other than the system volume.

Windows 10 recovery flash drive

The tool is called the Windows recovery disk, but in the "ten" it should have been renamed the recovery flash drive (we will use this particular term).

If earlier in the OS from Microsoft there were utilities for performing automatic resuscitation of the system, which in most cases only tried to do something, then in the top ten there is an option to create a system image for the subsequent return of the system volume to the state captured in this image by automatically reinstalling the OS as discussed in the section above.

A similar image is created in the following way:

1. We call the Control Panel applet called "Recovery".

3. We mark the option of backing up system files to a recovery flash drive in order to be able to perform an instant reinstallation of the "dozens".

4. At the end of all recording operations or, if necessary, boot from the created drive using the Boot Menu function.

5. In the action selection window, go to the "Diagnostics" section.

While in it, we will open the opportunity to perform the following operations:

• using a flash drive with an image, return Windows 10 to its previous state;
• visit UEFI/BIOS settings;
• resort to resuscitation of the "tens" through the rollback point;
• run via the command line, for example, to create a copy of the bootloader on the corresponding volume;
• restore Windows 10 from a full OS image.

The presence of such a flash drive in the case of the "ten" is much more useful than even the installation one, although the latter allows you to run some of the operating system recovery operations on the screen with the "Install" button immediately after selecting the language.

We create a complete image of the resuscitation of the system

Preparing for automatic recovery consists of taking a snapshot of Windows 10 to its current state. It is best to create such an image immediately after installing the operating system with all drivers and software, while the system volume is not littered, like the registry.

It is not necessary to create a snapshot in the first hours of the operation of the new OS, this can be done a couple of days after reinstalling it, so that Windows gets used to it and is brought to a normal functioning state, but does not have time to acquire junk files and registry keys.

1. The process begins with cleaning the C drive from the garbage: the system registry and uninstalling programs that turned out to be unnecessary.

5. Decide on the storage location for the snapshot of the operating system and the partitions that will be backed up (it is best to specify a removable drive).

After the compression of system files is completed and transferred to the specified digital media, it can be used to quickly return Windows 10 to the state captured in the image. In order to start recovery from the image, you must boot the computer from the USB flash drive on which the file is stored, or through the Windows 10 installer ("Diagnostics" - "Advanced options" - "OS image recovery").

Windows 10 rollback points

There are no innovations with this function, all its features work as in previous versions of the OS. It provides a chance to return the system to one of the saved states through the recovery environment or in a working operating system. To take full advantage of a feature, it must be enabled. You can check the status through the Control Panel applet under the name "Recovery". In the window, click "Configure System Restore".

To change the settings, click "Configure" and specify the space allocated for storing rollback points on the system disk.

When using a licensed image, this feature is activated, but if you installed Windows 10 downloaded from pirated sites, the build author may have disabled this feature. How to enable system restore? Select the system partition, click "Configure" and move the checkbox to the "Enable system protection" position.

Usually, rollback points are generated automatically in cases where changes are made by the user or any applications regarding system files, settings, services, and registry settings. The option to manually create restore points is also available. In the "System Properties" window, click "Create" and enter the name of the snapshot to make it easier to identify it.

To use the system rollback function using one of the restore points, go to the same applet and click "Start System Restore". In the case when Windows 10 does not start, we boot from the recovery disk or installation distribution and call "System Restore" through "Advanced Options" in the diagnostic window.

File History

Another innovation of Windows 10 that allows you to make and store backup copies of the specified files (often text documents and various projects) and extract the necessary copy of the file from the backup if necessary.

As you can see, the "ten" has an expanded set of effective functions for returning the system to a working state in any case and without reinstalling the OS. In addition to all the listed tools, you should definitely include the bootloader recovery function using Windows 10.
