How to recover windows 10 from a recovery flash drive. Every Windows user should have such a flash drive. Windows installation flash drive from a system image

Image Windows Recovery 10 is an official tool with which you can restore your OS if problems happen to it. You have two ways to get a look. The first way is to download the Windows 10 recovery image from the Internet. The second way is to create this image yourself, when your system is still running as stable as possible. Ideally, if you choose the second method. It is best to create an image at the moment when you just installed the OS. At this point, your system is as close to a clean state as possible.

How to use a Windows 10 recovery image

The Windows 10 recovery image must be written to a flash drive. After all, if problems happen to your computer, then you will not be able to use the data recorded on your hard drive. Therefore, no matter which of the two methods you choose, you must write data to USB flash drive. The recovery image requires a flash drive of at least 4 GB. We recommend creating such a flash drive immediately after you have installed the system. You have 2 ways how you can get a recovery image:

Create an image on your computer;
Download the Windows 10 recovery image from the Internet;

The first option is to create an image on your computer, better. Since in that case we are talking about a full-fledged image for recovery. You can restore exactly your version of the OS. If you use the second option - restore from an image from the Internet, then you will use the usual clean version Windows 10. And this is not exactly a recovery image, it's just a full version of the OS. On its basis, you can also restore the performance of your Windows versions 10. But this recovery will take place without taking into account the features of your particular computer.

You cannot download a recovery image for your computer. You can only create a personal image yourself, because it is unique. Of course, the image is created even at that moment, until you have any problems. Experts recommend creating images regularly. For example, every six months or a year. The image should always be at hand. After all, a computer can be disabled at any time. If you do not have a ready-made image, and the computer is broken, then you will need a second device on which you will create a Windows 10 recovery image from Windows image 10. Of course, for this you must read the instructions,

The new Windows 10 operating system from Microsoft has already gained popularity among millions of PC users around the world. But like all new products, Windows 10 is not without flaws. Many users of this OS experience bootloader problems. Most often, this problem occurs due to a new operating system update policy.

Now in Windows 10 you cannot turn off updates, as it was in Windows 7 and XP.

The very same problem with the bootloader manifests itself when the user does not wait for the system update to finish and turns it off the POWER button.

After the user turns on the computer again, he meets such a message on the screen of his monitor.

This message indicates that your bootloader is corrupted and needs to be repaired. It is also worth noting that turning off the computer during the update is not the only reason for the breakdown. The bootloader can still be damaged viruses and various malware. Another fairly common cause of failure is faulty HDD, which are bad sectors , that is, the boot record will be located on these sectors. Also, the cause of the bootloader crash can be installing a junior OS on top of Windows 10. To help our readers restore the bootloader, below we have prepared examples in which we will describe in detail how to restore it.

The easiest way to recover

When a PC user sees a message about a bootloader malfunction, the first question that arises for a PC user is how to restore the Windows 10 bootloader. In this example, we will describe the easiest way to restore it. For this example, we need .

If you do not have this disk and Internet access, you can make it on another computer with the same OS.

You can also use the original Windows 10 installation disc for this task. Well, let's get started. Insert the recovery disk into the drive and boot from it when the computer starts.

In the first window of the Recovery Disk Wizard, you must specify keyboard layout, which will open the wizard menu.

In this window, we will select the second tab " Troubleshooting” and immediately go to the next “”.

In the additional parameters, we are interested in the "" tab. After clicking on this link, the wizard will ask you to select an OS to restore its launch.

The computer under test has one Windows 10 operating system installed, so there is only one choice in the wizard. Once the OS is selected, the system will begin troubleshooting the computer and should repair the corrupted bootloader.

If using this method you fail to return Windows 10 to working order, then in the following examples we will describe the detailed process of restoring the boot sector using system utilities diskpart and BCDboot.

Restoring the Windows 10 bootloader using the command line

For this method, we also need Windows 10 recovery disk. Let's boot from the disk, as in the previous example up to the item "". In this menu, we are interested in the "" tab, which we will go to.

First of all, we will run the console utility on the command line diskpart. To do this, in the console, enter the command diskpart

We need this tool for displaying information about all local drives in system. Now we need to find the bootloader partition number. This is usually a hidden partition that takes up 500 MB. This partition is created automatically by the Windows 10 installer. Next, to search for it in DiskPart, we will enter the list volume command

From the image you can see that the partition with the boot record is in the first volume on the C drive. You can also see from the image that Windows 10 itself is installed on the D drive. Now we have to exit disk program. You can do this with the exit command.

After exiting DiskPart, enter the command bcdboot.exe D:\Windows Also note that the command uses drive D, since it is on it that ten is installed.

This command completely restored dozens of boot files. The principle of this command is to use the utility BCDboot. The developers specifically created this utility to work with boot Windows files . It is also worth noting that thanks to the same utility, the Windows installer creates a hidden partition and copies boot files to it.

Restoring the Windows 10 bootloader using the command line (Method two)

In the second method, we will also use the utilities diskpart and BCDboot and try to overwrite the bootloader. To do this, run DiskPart and find out on which disk our hidden partition and the partition on which Windows 10 is installed are located. The launch of this utility is described above.

Now we need to format the hidden partition, which is located in the first volume. To do this, we will type the select volume 1 command, which will select our hidden encrypted partition with a size of 500 MB.

The next step is to format the selected partition. This is done in order to erase all files from it. For this operation, enter the command in the console format fs=FAT32

After formatting our partition, we will exit disk utility and enter the new command bcdboot.exe D:\Windows that was entered in the previous example.

This command will not fix the bootloader files as in the previous example, but create new. As you already understood, this method is used if the first one did not work.

Another Way to Repair Windows 10 Boot Using Command Prompt

This method requires a utility bootrec. Unlike the previous utility, this utility does not restore bootloader files, but restores boot record . That is, she restores the MBR- the first sector on the HDD. It is very important for the operating system that the MBR is safe and sound. When the computer starts, its BIOS first of all looks for the MBR to start the operating system from it. For this example, run, as in the previous examples, command line. The utility in question has two main commands /FixMbr and /FixBoot The first command is required to fix MBR, and the second creates a new. First of all, consider the situation when our MBR is damaged. To do this, enter the first command in the console.

In the image above, you can see that the operation was successful, which means that the MBR has been restored.

Now consider a situation where the first method does not work, that is, we will create a new one MBR sector. To do this, we use the second command.

From the image above, you can see that the new MBR sector was created successfully.

The examples show how easy it is to restore the MBR sector using the Bootrec console utility. If you have problem with start m Windows 10, we recommend using this example first.

We clean the system from malware before restoring the bootloader

If the cause of the bootloader crash is malware, then this malicious code must be removed before recovery. It will help you in this situation. This is a rescue disk has a lot of tools for restoring a computer, as well as treating it from viruses. You can download Dr.Web LiveDisk on its official website www.drweb.ru. This Live CD is based on linux and is free. This CD is distributed as iso image, which can be written as optical disc as well as to a USB flash drive. After burning the image to disk, launch Dr.Web LiveDisk.

AT start menu select the first item and continue downloading Dr.Web LiveDisk. After a few seconds, the OS based on Linux, which is actually Dr.Web LiveDisk, should start up.

In this operating system, you can completely clean your computer of viruses and even make a backup of all information.

Also useful is the fact that this OS has full Internet support and a built-in browser Firefox.

Summing up

In conclusion, I would like to say that if you know all the intricacies of bootloader recovery, then you can quickly fix your computer. It is also worth paying attention to the situation when it is impossible to restore the boot sector and the bootloader itself. In this case, you need to play it safe and use the means full recovery systems. These means are full image systems, created by means of the Windows 10 OS itself, as well as a program such as Acronis True Image. We hope that our material will help you restore the bootloader from the MBR, and the computer will function as before.

Repairing the Windows 10 bootloader with automatic troubleshooting

In my example, we will try to restore the Windows 10 UEFI bootloader. Article fit for users with computers that have an MBR bootloader in Windows 10.

After loading on the computer, in the first window of the program Windows installation click on the "Next" button.

In the next window, click on System Restore.

In the Select Action window, click on Troubleshooting.

First, I recommend choosing the method: "Startup Repair". The Windows operating system will automatically fix problems that prevent the system from booting. This is the simplest solution to the problem, I myself have used it more than once.

The operating system automatically diagnoses the cause of the failure and recovers system files needed to boot Windows.

In case of a positive outcome, the computer will Windows startup 10 in normal mode.

If Startup Repair failed to repair your computer, you will have to use the command prompt.

Restoring the Windows bootloader via the command line - 1 way

After an unsuccessful automatic recovery, in the Startup Repair window, click the Advanced Options button.

In another way, you can re-boot from bootable media (USB flash drive or DVD), and then go all the way to the "Advanced Options" window.

In the "Advanced Options" window, click on the "Command Prompt" button.

We will perform a Windows bootloader repair via the command line. The bootloader recovery process will take place in two stages:

using the Diskpart utility we will find out the name system disk on which Windows is installed;
then we will create the operating system boot files.

In the command line interpreter window, enter the command to launch the Diskpart utility (press the "Enter" key after entering each command):

Diskpart list volume

In the list of disks (volumes) of the computer, you need to find system partition on which the Windows operating system is installed. We need to find out the “Name” (drive letter), when searching for a volume, be guided by the size of the disk with the installed system. The operating system can be installed drive "C", "D", "E", etc.

In my case, the system is installed on the "C" drive.

To exit the Diskpart utility, enter the command:

Now you need to enter a command to create operating system boot files using the bcdboot utility.

In the command prompt window, enter the command:

bcdbootX:\windows

In this command, "X" is the letter of the volume (disk) where the system is installed, on my computer drive "C", so I entered this drive letter.

After executing the command, you will see a message that the download files were created successfully.

Close the command line window.

In the "Select Action" window, click the "Continue" button to exit System Restore and continue Windows usage 10.

How to repair the Windows 10 bootloader using the command line - 2 way

This method will use the command line called from the recovery disk, bootable USB flash drive, or from the Windows installation DVD. The computer must boot from the boot disk, and then run the command prompt.

The process of creating Windows 10 boot files will take place in three stages:

using the DiskPart utility, we will find out the number of the hidden volume (disk, partition) and file system, format the disk, and then give a letter to the volume (disk);
creating files on a hidden volume (disk) to boot the system;
deleting a drive letter (volume) of a hidden partition.

In the command line interpreter window, type the commands in turn (do not forget to press "Enter" after entering the appropriate command):

Diskpart list volume

On a computer with GPT UEFI, there is a hidden partition with the FAT32 file system, it is not marked with a letter, ranging in size from 99 to 300 MB. On computers with an MBR BIOS, there is a hidden volume with the NTFS file system, up to 500 MB in size.

We need the volume number ("Volume 0", "Volume 1", "Volume 2", etc.) and its file system. Pay attention to the letter of the volume (drive) on which Windows is installed.

Select the hidden volume, it doesn't have a "Name" (drive letter). In this case it is "Volume 4", your computer may have a different volume number.

Select volume X

Enter the command to format the volume in the "FAT32" or "NTFS" file system, depending on the UEFI or MBR hard disk partition style, respectively. On my computer, the hidden partition is formatted as FAT32, so I chose to format it to that file system.

format fs=fat32 or format fs=ntfs

Assign letter=Z

Exit the Diskpart utility:

Now you need to run the command to create Windows boot files:

Bcdboot C:\Windows /s Z: /f ALL

In this command, "C" is the letter of the partition on which Windows is installed, and "Z" is the letter of the hidden drive.

Once the download files have been successfully created, run the Diskpart utility again:

diskpart

Display a list of computer volumes on the command line:

List volume

Select the hidden volume that you previously assigned the letter "Z" to:

Select volume X

In this command, "X" is the number of the hidden volume on your computer. You already selected it on the command line when you assigned a name for this volume (partition).

Enter the command to remove the volume name (drive letter), and then exit the Diskpart utility:

Remove letter=Z exit

Close Command Prompt.

Remove the DVD or bootable flash drive from the computer, bootable media is no longer needed.

In the "Select action" window, click the "Turn off" button.

Turn on the PC, which will boot into the Windows 10 operating system again.

Windows 10 bootloader recovery in Bootrec

You can use the Bootrec.exe utility to troubleshoot startup problems on computers with an MBR (Master Boot Record).

The main commands of the Bootrec.exe utility are:

FixMbr - Windows compatible master boot partition (MBR) entry, existing partition table is not overwritten.
FixBoot - writing a new boot sector compatible with Windows to the system partition.
ScanOS - search on all drives installed systems compatible with Windows to display entries that are not in the system configuration store.
RebuildBcd - Searches all disks for installed Windows-compatible systems, selecting which systems to add to the configuration store.

In most cases, it is enough to write down the main boot partition or a new boot sector that is compatible with the current operating system.

After booting into the Windows Recovery Environment. In the command prompt window, enter one of the commands:

Bootrec.exe /FixMbr Bootrec.exe /FixBoot

If the problem cannot be solved by the suggested methods, you can fix the problem using a "clean" instead of the system installed on the computer.

Article Conclusions

In case of problems when loading the operating system, the user needs to restore the Windows 10 bootloader. To do the job, you will need to boot on the computer from a bootable USB flash drive or from the installation DVD. Restoration is performed from the recovery environment automatically by the system, or manually by the user, after entering the appropriate commands on the command line.

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 boot 10, storage media selection, thermal sensor range is indicated, various parameters are configured. If the system stops booting, errors fly out and perform a recovery in a standard way fails, you can through the BIOS.

How to restore windows 10 through bios.

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.

The regular ability to create a Windows 10 emergency recovery disk was inherited from the "seven". They create such a disk in case there are difficulties in the operation of the OS that prevent loading and contains tools such as:

Automatic troubleshooting that prevents system boot;
Restoring from a previously created image (backup);
Returning the OS to the rollback point.

How to create a rescue disk with regular ones Windows tools 10 and how to apply it in practice in case of problems with system boot? These issues will be discussed in detail below.

When is a recovery disk needed?

A recovery disc can only be created for computer devices that have a CD/DVD drive in their assembly. Unlike bootable rescue media from third-party developers, most of which provide for recording to a USB flash drive, a rescue disk can only be burned to a CD / DVD disc. But this is by no means an infringement on the capabilities of owners of devices without a CD / DVD drive. The fact is that the recovery disk is not the only means of accessing the standard Windows resuscitation capabilities. AT system environment Recovery can be accessed using a Windows 10 installation disc, which can also be created using a flash drive.

To reanimate the current OS using its installation disk, no financial costs will be required. The distribution kit with Windows 10 on the Microsoft website is available for free. It is delivered through the Media Creation Tool, you need to download and run it.

Utility in a single process and Windows distribution 10 downloads, and immediately creates a bootable USB flash drive. If you have problems booting the system, you need to boot from a USB flash drive and, at the stage of starting the installation of a new OS, select the item indicated in the screenshot below. Access to the toolkit does not require a product key.

As you can see, the rescue disk is so essential tool hardly call. However, its presence is welcome if there is no other computer in the house with which one could quickly create a bootable USB flash drive with the system installation files.

Preparing to restore Windows

A rescue recovery disk is created for a specific Windows bit depth 10. In this case, the universal rule applies, as for programs installed inside the system - 32-bit bit depth is suitable for both 32-bit and 64-bit Windows 10. Whereas a 64-bit rescue disk is useful only in case, respectively , 64-bit version.

There will be little use from the rescue disk if a rollback point has not been created inside the OS itself or a system image has not been prepared ( backup copy).

Create a recovery drive

The emergency recovery disk is part of the standard toolkit for backing up OS files. This functionality is located in one of the sections of the control panel. To section Reserve copy can be reached not by wandering around the control panel, but by in a simple way- using internal search. In Windows 10, the search button is located right in the taskbar, so it’s a sin not to use this convenience.

Enter in the search field key query the desired partition and directly get to the system backup settings.

Click the "Create System Image" button. Select the CD / DVD drive in the drop-down list, if there are several. Next, click the "Create Disk" button.

We will see a notification, which, in particular, refers to the bitness of the OS.

Creation completed.

The Windows 10 recovery disk is suitable for computer devices as it is based on a regular BIOS firmware, and with BIOS UEFI.

Now the rescue disk can be put somewhere in a secluded place. His further fate is to wait for a critical failure of the system.

Boot from rescue disk

Let's say Windows 10 won't boot. Now is the time to use the emergency equipment. We take out the recovery disk and put it in BIOS boot from a CD/DVD drive. We confirm by pressing any key to boot the device from CD / DVD.

The interface is in Russian, but you can choose any other keyboard layout. In our case, just confirm Russian.

The choice of action is the "Diagnostics" section.

In the next window, we will see all the available Windows 10 recovery tools.

Boot recovery

To try to solve the problem with Windows 10 not booting, you can first use the boot troubleshooting method. This is a mode to automatically fix problems that prevent the OS from starting.

Don't put too much hope in this tool. Like the in-system auto-troubleshooter, the boot-troubleshooter will not be of much use. After a short diagnosis of the computer, in most cases it will be declared inability to solve the problem.

Rollback to a restore point

The rollback point is the most convenient toolkit that allows you to, with minimal data loss. Naturally, it is necessary that rollback points are periodically created - either manually by the user, or automated (using the task scheduler). The process of creating a rollback point takes much less time than the process of creating a system image (backup). And the rollback point saves space on the PC. However, the rollback point is more vulnerable than a backup that can be stored on an alternative hard drive and will come in handy if the main drive fails.

In order to roll back to an earlier state of the OS in the face of serious problems with the system, we boot from the emergency disk, go through the path to additional parameters and select the first option in a row.

Select the current rollback point from among the existing ones. The most complete list of them will be available after setting the option to show other points. Click "Next".

Click "Finish" in the rollback confirmation window.

We additionally confirm the launch of this process.

After the system rollback is complete, the computer must be restarted. After the reboot, we will find the system exactly in the state in which it was at the time the rollback point was created.

Restoring from a system image

If it was previously created using the regular backup functionality, and the OS suddenly stopped loading, it's time to use this image by booting from the recovery disk. Having reached, as indicated above, to the menu additional options, so we choose the second option.

We leave the image found by the system by default or select another one using the appropriate option in the first window. Click "Next".

Click "Finish".

We confirm the decision with the "Yes" button.

As with the rollback point, the system will be returned to the state it was in when the image was created.

Have a great day!

Just about the complex. Programs. Iron. Internet. Windows
