Programs to restore the hard disk boot sector. Restoration of the boot sector

Windows 7 bootloader stops working for many reasons - when damaged boot.ini or an attempt to install XP along with the "seven", after which the latter does not want to boot. This is due to the fact that XP produces rewriting boot record MBR Windows 7. Usually, Windows 7 bootloader recovery is carried out by standard system tools. You can use another tool, such as Bootice.

The easiest way to restore the loader

If when pressing F8 does not open additional ways Launch and troubleshooting means, you will need to use the Windows 7 recovery flash drive. From this drive, you will need to download the computer to the recovery environment by clicking on the system recovery link at the bottom of the OS installation window.

  1. The computer will automatically try to find a solution to the problem, which will notify you in the window that opens.
  2. If the recovery utility can cope with the task, it will only be rebooted.

If you cannot restore the Windows 7 bootloader after XP, use the startup recovery tool that along with others is part of installation disk or flash drives. Usually these simple ways Can cope with uncomplicated MBR launch issues.

Edit boot.ini

For the launch of the default system, Boot.ini is responsible. If it is wrong to install or delete one of the OS, its entry will be stored in the same boot.ini. It is located in the root of the system partition, so to edit it, you need to configure the computer to display hidden files.

Sometimes boot.ini can be spoiled by a virus or some program could contribute, after which the OS does not start independently.

Fix it easy - boot from LiveCD and edit boot.ini by the usual notepad. There are only two partitions - Boot Loader, loading and operating Systems. You should remember the value of several parameters:

  • timeout \u003d 10 - time in seconds during which the user can select OS to start;
  • multi (0) and Disk (0) - parameters that must have zero values;
  • rDISK (0) - the disk number with the system partition (the countdown is kept from zero).

In general, boot.ini from one OS should look like in the picture.

Use command line capabilities to restore the MBR sector

You can get into command line mode from the same boot disk or flash drive, opening a system recovery tool and selecting the latest paragraph " Command line».

  1. Enter the BootRec command and click after that enter, will appear full list opportunities;
  2. Write down the MBR sector, for which there is a bootrec.exe / fixmbr command;
  3. On the successful completion of the operation after clicking Enter, the computer will notify the user in the next line;
  4. Next, spend the procedure for recording the new boot sector, for which you enter bootrec.exe / fixboot;
  5. It will only be left to enter an exit and try to restart the computer.

  1. Enter the command line from the installation disk or flash drive;
  2. Enter bootrec / scanos, after which the utility scans the computer for availability operating system;
  3. Write B. next line command BootRec.exe / RebuildBCD, the program will offer you to make all the Windows versions found in the launch menu, including XP et al.;
  4. It will remain to agree with this by clicking successively y and ENTER, after which you will have a choice when loading the system you will have a choice of ok - XP or seven.

Eliminate the problem with MBR can also be another command. To do this, you need to enter BootSect / NT60 SYS, then ENTER. Enter to exit EXIT. As a result, the main boot code will be updated, and your systems will appear in the list during loading.

With serious problems, the described methods to restore the MBR may not work, so it is worth trying to overwrite files located in the download storage.

Bootmgr Is Missing

Such a message on the black screen computer usually issues when damaged or deleted the MBR sector. The reason may not be associated with the MBR, for example, if the BIOS flights the BOOT tab settings and the system is trying not to boot from that disc. But it is more likely to blame the bootloader, so we describe how to restore Windows 7 boot.

On the disk with Windows 7 there is always a small 100 megabyte reserved hidden partition, for recording boot files OS, including damaged bootmgr. You can simply copy bootmgr from the installation media and write to this section. For this:

  1. Go to the command line from the recovery disk.
  2. Enter the DiskPart and List Volume command sequentially, after which the list of your disks and letters that the system assigned to each of them will appear on the screen. We are interested in a reserved section of 100 MB and optical drive - C and F discs, respectively, as in the picture.
  3. Enter Exit and press ENTER to exit.

Enter the letter of the setting disk with a colon and the command to copy the bootmrg bootloader to the reserved section. It will look like this:

  • F: and further enter;
  • copy bootmgr c: \\ and press ENTER;
  • EXIT, utility will complete work.

If the copying to the hidden partition fails, the download repository can be completely overwritten. Windows 7 boot recovery is made by the bcdboot.exe n: \\ Windows command, where N is the disk letter with the OS. After it is reported that the files are created successfully, you can leave the EXIT command tool and restart the computer.

  • record the DiskPart line on the command line, which causes the utility;
  • to display all available physical disks write List Disk;
  • selects disc command SEL DISK 0, where 0 is the number of the only HDD installed;
  • to display all partitions of the hard drive, enter List Partition;
  • for selection reserved section Record the SEL PART 1 command, where 1 is the section number;
  • make it active by entering Active;
  • exit the application by writing EXIT.

In the extreme case, you can completely manually delete and format the system section, making starting from any LiveCD, and then the BCDBoot.exe command to create a new one.

We use Bootice.

If Windows XP was installed after the "seven", due to the rewritten MBR sector, only XP is launched and you do not have the choice of the system after you turn on the computer. At the same time, both systems are fully working, and return the start menu can be very easy to use the Bootice utility:


In a new bootice window on the left you will see a list of OS downloads, in which you will need to add to Windows XP missing "seven":

  • click "Add";
  • in the list that opens, select a new line windows records 7;
  • in right side In the top box to enter hDD;
  • in the box below, specify a section with "seven";
  • click on Saving the main settings.

The program will notify you about successful change. this element Boot and Bootice can be released. When you turn on the computer next time, you can already choose which OS is loaded with hard disk - Windows 7 or XP.

Windows 7 download recovery

Friends, many of you more than once have problems with the operation of the operating system and you asked the question how to restore Windows 7 download and make the operating system loaded normally. In this article, we will consider the most common ways to restore Windows 7 bootloader, which help in most cases.

Load from the installation disk or flash drive with your windows version 7.

If you do not have a suitable flash drive, it would be time for her to get it.

The main thing is to coincide the size of the system (32-bit or 64-bit). Also, it is desirable to match the release (Home, Professional, Ultimate).

Instead of installation, select "System Restore".

Get to the "System Recovery Settings" window and select the Run Repair Tool.

After that, the recovery program will search for errors in the boot sector and boot section of Windows 7 And when discovering, will try to fix them. After that, the system is restarted and the Windows 7 may be loaded normally.

If the first time was not able to restore the download using the Windows 7 recovery tool, then try to repeat this process another 1-2 times. It often helps, since the recovery means cannot always eliminate several problems in one pass.

2. Restoring Windows 7 download using the command line

If you failed to recover Windows 7 download using an automatic recovery tool, then try to do this using the command line, it's easy. If your computer does not work as fast as I wanted to install SSD Disc And you will get a significant productivity gain! ASP900S3 75E120BW F120GBLSB.

Load from the installation disk or flash drives with your version of Windows 7 and instead of installation, select "System Restore".

Get to the "System Recovery Settings" window and select the "Command Line" recovery tool.

After that, a window with a black background appears in which you will need to write several commands.

Enter the following commands in turn:

bootrec / fixmbr
bootRec / FixBoot
bootSect / NT60 All / Force / MBR
eXIT

Language switching is performed by combining the "ALT" + "SHIFT" keys. After entering each command (string) you need to press the Enter key.

Then restart the computer.

After that, in most cases, the problems associated with the boot sector and the Windows 7 bootloader will disappear and the operating system will be loaded normally.

If after using the command line, Windows 7 is still not loaded, then try to use the automatic download tool again, as we considered above.

3. Restoring Windows 7 boot with reinstalling system

If you failed to restore the operating system boot to the methods described above, you will most likely have to reinstall Windows 7 by removing partitions.

Before reinstalling Windows 7, copy all the most important files from your hard disk to external disk or flash drive. This can be done using any LiveCD boot disk. Note that the external disk or flash drive must be connected to the PC before loading from LiveCD, otherwise they may not find it.

TRANSCEND TS1TSJ25M3.

If, due to the download errors, you will not be able to reinstall Windows 7, then delete from the disk of all partitions using a third-party utility, for example, bootable acronis disk Disk Director. After that, try to install Windows 7 again with the creation of new sections.

If reinstalling Windows 7 At the disc configuration stage (Creating partitions, Selecting the section for installation) or when you restart the computer during installation, you will have former download errors, then run the command line and execute the commands that we have considered above.

The command line at the disk setup step can be started using the "SHIFT" + "F10" key combination.

If you have other installation problems:

  • windows does not see the disk
  • Unable to install Windows to this disk
  • Selected disk has GPT sections style

read our articles on installing Windows 7, Windows 8.1 and Windows 10. There are also tips on breaking the disk to the sections and describes the Windows installation nuances on the discs of large volume (3 TB or more).

4. Causes of Windows Download Problems

Most frequent reasons Windows load failure are:

  1. Failures B. hard work Disc and power supply
  2. Errors when installing multiple operating systems
  3. Errors using disk utilities
  4. Incorrect activators
  5. Installing Windows to the existing section along with the loader

In order to prevent problems with downloading in the future, you need to determine what exactly led to the problem and not repeat these errors.

If you have found another reason that caused the problem with Windows loading, or another way to solve the problem, please write about it in the comments

How to restore the launch of Windows 7 via the command line

Fix tools windows errors Constantly improving, offering users more and more automated solutions that allow you to quickly eliminate various problems. If you connect the installation media to the computer and select "Restore Start" to the computer, then you can correct the set of errors that interfer Windows startup. However, if the loader is damaged, this method does not work, so if you encountered such a problem, you will have to produce restoring MBR Through the command line.

Running the command line

You will need boot disk With the distribution system of the same system that is installed on the computer. Not only the version, but also the discharge of Windows, otherwise, the recovery does not work out otherwise.


Opening a list of available tools, first fix the startup error. If you cannot solve the problem of damage to the bootloader, return to the list of means and select the command line.

BootRec Utility

To overwrite the MBR (data required for loading windows) and correct loader errors we will use the built-in in windows utility. Enter the BootRec command in the interpreter window. After starting this utility, a list of supported commands will appear - follow them in order.


Restart the computer. The bootloader restores, MBR is overwritten, so windows must start without problems. If the MBR is not helped to resolve the launch problem, try to apply the remaining two commands:


The utility will start scanning the hard disk, trying to find systems installed. When Windows 7 is detected, run "bootrec.exe / rebuildbcd". Found systems will be recorded in the download menu. Exit the utility using the "EXIT" command and restart the computer. Overwrite the MBR no longer need - windows will start without errors.

Utility BCDBoot

If you cannot correct the MBR error fails, try to restore the bootloader by applying the BCDBoot utility. This tool allows you to create or restore the download medium located in the active section of the hard drive. If, as a result of the system malfunction, the loading medium has been transferred to another partition of the hard disk, then using BCDBoot.exe you will return it to the place.

Open the command line and enter "BCDBoot.exe E: \\ Windows" (attributes to enter optional). Instead of "E:" you need to put the letter of the section on which they are stored wINDOVS files. If in windows Environment This section is indicated by the letter "C", here it can be displayed as "D" - consider it when executing the command.

After completing the operation, restart the computer and try to start Windows again. The damaged download environment will be restored, and the system starts without errors.

How to restore Windows 7 and Windows 8 bootloader

What is Windows loader? Called by the simplest language - this program provides the operating system loading immediately after the computer is turned on. If you consider the evolution of Windows operating systems, then in Windows 2000 and Windows XP Windows loader was NTLDR (NT Loader), which is able to upload other operating systems, setting the appropriate boot sector in separate file. But with the advent new system BIOS - EFI and UEFI - Old NTLDR no longer complied with the requirements. Beginning with windows Vista. And then, in Windows 7, Windows 8 and Windows 8.1, a new boot manager (download manager) was applied - bootmgr. Its work is closely related to the main boot record (MBR) or the main boot sector (MBS). When loading a computer, after checking the equipment, the BIOS reads the first sector from the boot hard disk - 512 data bytes. MBR can occupy and more than one sector, but now it's not about that. In the MBR there is a primary bootloader code and a hard disk partition table.

In case of damage to the bootloader or boot record, your operating system is whether Windows 7, Windows 8 or Windows 8.1 - will issue a BootMGR IS Missing error - Press Ctrl + ATL + Del to Restart.

In some cases, the BootMGR IS Corrupt error is issued. THE SYSTEM CANNOT BOOT:

In this case, you can no longer be running Windows operating system in as usual mode.

Note: First of all, before resorting to fundamental action, check, it is possible that the load sequence is simply incorrectly set. hard diskseither bIOS settings were simply reset to default (this happens when the CR2032 battery is sitting on motherboard). This is particularly often found on computers where 2 or more hard drives are installed. You just need to go to the computer's BIOS and check which one is based on the download. To do this, when loading, when the primary diagnostics of the hardware (white letters on a black background) is pressed several times the Delete button. The BIOS screen should open. We are looking for in the BIOS sections item "Hard Disk Boot Priority" or simply "BOT DEVICE PRIORITU" and choose it:

Before changing something, you need to know - on which of the disks the operating system is installed. If you do not know - put in turns each of the hard drives first, press the F10 button to save and try to boot. The main thing is to remember which disk first stood first and if the sequence of the sequence does not bring the result, return everything as it was.

How to restore Windows bootloader.

There are two recovery paths: using standard tools from Microsoft and using third-party programs. In the first version, you need a boot disk or flash drive with the original way Windows 7 or Windows 8. The third-party assembly of Windows may not approach, since it all starts at many builds immediately from the start of installing the operating system. In case of use by third-party programs - you will fit the Hiren's Boot CD boot disk.

Restoring the bootloader using Microsoft tools.

Method for Windows 8 and Windows 8.1

Step 1. Restart the computer, when loading, press the Delete button and get into the BIOS. In the "BOT DEVICE PRIRITU", you need to set the CDROM value in case of disk or USB in case of use boot flash drive.

Step 2. When booting from the disk, the Windows Installation window should open:

At the very bottom, select the "Recovery System" item. Hard disks will be checked and a list of available operating systems will be displayed. Often in the list one item, it should be selected:

The "Select Action" window opens:

Click on the "Diagnostics" icon - the section menu will open:

Select the item "Advanced Parameters".

Step 3. Select the "Automatic Recovery" item:

Run the system diagnostics. If some error is detected, then you will be displayed a message about it. Then you need to click the Fit button and wait for the end of the fix and reboot the computer.

Step 4. In case automatic recovery did not reveal problems during diagnostics or did not help and during startup still Windows 8 is not loaded and the BootMGR IS Missing error appears, then you turn off the disk again and in the "Advanced Settings" section of the diagnostics select the "Command Line" item:

The Windows 8 or Windows 8.1 command line opens.

Step 5. In the team windows string 8 We enter the command: bootrec.exe / fixmbr Click ENTER. The "/ FixMBr" key is used to write to the main boot record system compatible with Windows 8 and Windows 8.1. This parameter does not overwrite the existing partition table. Then enter the command:

bootRec.exe / FixBoot

And press ENTER again.

The "/ FixBoot" key is used to write to the system section of the new boot sector using the boot sector compatible with Windows 8 and Windows 8.1.

Reboot your computer and check the download of Windows 8.

Step 6. If after rebooting the BOOTMGR IS Missing - Press Ctrl + Alt + Del to Restart error, you cannot start the command line where you type the BootRec.exe / RebuildBCD command / RebuildBCD is used to complete the configuration data. The result of the execution of the program with this key will scan the hard disk for the presence of the Windows operating system and the request for adding it to the download list.

Press - yes (y) and reboot the computer and check.

After the above operations, it is usually possible to recover Windows 8 and Windows 8.1 bootloader. If the methods presented did not help, then you need to try to restore the download using third-party programs. And if they do not help - reinstall Windows 8, as it is likely to help anything else.

Method for Windows 7.

Step 1. Restart the computer, when loading, press the Delete button and get into the BIOS. In the "BOT DEVICE PRIRITU" section, it is necessary to set the "CDROM" value in the case of a disk or USB in the case of using the loading flash drive.

Need the parameter "1st Boot Device.»Assign the value" CDROM "(or USB-HDD for a flash drive). Click F10 to save the BIOS configuration. Reboot your computer.

Step 2. When booting from a disk, you will see such a window starting to install Windows 7:

Here you need to select the "System Restore" item. After checking hard drives, you will be shown a list of available operating systems:

As a rule, the list is only one system, although there are users who have 2, 3 or more operating systems on the screw. But this is less common. Click the Next button and the "System Recovery Settings" window opens.

Step 3. Select the "Start Restore" item. Diagnostics of the system will be carried out. If an error is detected, you will see a message:

You will need to click the "Fix and Restart" button. After that, the system should boot in normal mode.

Step 4. If, after rebooting, the normal download of Windows 7 has not been recovered or during the diagnosis of the system of problems is not revealed:

You need to select the "Command String" section in the Recovery Settings window:

Step 5. In the Windows command prompt, enter the bootrec.exe / fixmbr command and press ENTER. Then enter the bootrec.exe / fixboot command and click Enter. About what you mean keys / fixmbr and / fixboot I have already written above.

Reboot your computer and check.

Step 6. If after rebooting the computer, the bootloader does not recover and the BootMGR IS Missing error is not eliminated - start the command line and recruit the command: bootrec.exe / rebuildbcd

The "/ RebuildBCD" key searches for installed Windows 7 compatible operating systems and fulfills the load of the download configuration data. The result of the program will be scanning a hard disk for the presence of a Windows operating system and a request for adding it to the download list. Press - yes (y) and reboot the computer.

Step 7. If the Windows 7 download error has not been removed, that is, another method from Microsoft is a BCDBoot utility that is used to create a system partition or restore the download environment located in the system section. At the command prompt, you need to type the command:

bCDBoot.exe C: \\ Windows (if Windows is installed on another disk - correct the path in the command, for example on D: \\ Windows).

The result will be the message "BOOT FILE SUCCESSFULLY CREATED". Reboot your computer and check.

Restoring the normal boot of Windows using Hiren's Boot CD.

Unfortunately, there is no original bootable windows disk 7 or windows 8 at hand, and pumping it out of the Internet is very problematic. In this case, various small boot assemblies usually come to the rescue - the so-called LiveCD, which can also be recorded on the disk or flash drive. In my opinion, the most optimal, convenient and easy service set for restoring the Windows 7 or Windows 8 operating system is "Hiren's Boot CD". Utilities to restore Windows bootloader on the disk a lot, so I will show those who most often use system administrators: graphic program Paragon Hard Disk Manager and the MBRFIX Console Utility. First you need to download "Hiren's Boot CD", burn it on a USB flash drive or CD and set up the BIOS download from CDROM or USB-HDD, depending on whether you are loaded from the disk or flash drive.

If everything is done correctly, you will see the start menu "Hiren's Boot CD":

Option 1. Paragon Hard Disk Manager.

To start the Paragon Hard Disk Manager program, you need to select "DOS programs" or "Run dOS programs (Alternative method) ", and then subsection" Driving Disc Partition Tools "and, accordingly, Paragon Hard Disk Manager.

Now it is necessary in the main program window to select the menu item "Wizards" \u003d\u003e "Windows load recovery":

The Windows Load Restore menu opens:

Select the first item - "Search for installed Windows copies" and press the Next button.

The program scans discs and give a list of operating systems, in which only one item is usually. We put a checkbox "change the boot record" and press the Next button.

The Paragon Hard Disk Manager program will restart the boot record (MBR). Press the button is ready and reboot the computer.

Option 2. MBRFIX utility.

To start the MBRFIX utility, you need to select MINI Windows XP in the Hiren's Boot CD start menu. After the operating system boot, you need to press the "Start" button \u003d\u003e "HBCD menu".

In the HBCD menu that opens, you need to select PARTITION / BOOT / MBR \u003d\u003e "Commandline" \u003d\u003e "MBRFIX":

To restore Windows boot records (MBR) and Windows bootloader on a C: \\ for Windows 7, the command parameters must be as follows: MBRFIX.exe / Drive 0 FixMBr / Win7 / YES. To view disk information - you can enter the command:

MBRFIX.EXE / DRIVE 0 DriveInfo.

On Windows 8 and Windows 8.1, I have not checked this utility yet, because I can not recommend.

Restore the main boot record (MBR) in Windows 7

After the channel "Video Tips" was told about the simple method of installing two and more operating systems on one computer, reasonable questions were sprinkled, which would be if the second system is getting tired and the desire to remove it. Most likely, the bootloader will fly (if they are expressed by the language of motorists, then it's like a starter in the car) and you will see a black screen. Many people might think "Well, that's all, once again broke the computer." In fact, the system is installed and fully operational, but can not start.

It can also occur if the computer can install the systems in chaotic order and not adhere to the correct installation order: (C :) Windows XP, (D :) Windows 7, (E :) Windows 8.1 (F :) Windows 10.

In a word, the "loader" can "fly" by different or more exotic reasons, but it is not worth it to be afraid.

  • The main boot record (MBR) is the first sector on the hard disk in which there is a partition table and a small program loader, reading the data from which partition of the hard disk to load the system and in the future information is transmitted to the section with an installed operating system for Its downloads (somehow so 🙂).

Today, the conversation will be about Windows 7 (although the actions to restore the "loader" in other systems are the same). To do this, you need or an installation disk with the operating system, I hope you have not thrown it or a flash drive (if you don't have any other, read the article below). Turn on the computer. Click the button responsible for the entrance to boot Menu. And set the priority of loading from the drive or from a USB drive. Imagine that we are loading with optical disk. During the download, an inscription appears.

1. Press any key to boot with CD or DVD. We reach the Windows Installation window and click the "Restore System" button.

Probably the problems will immediately be discovered. Click the "Fit and Restart" button.

2. If it does not help and the system is still not loaded, reassemble the "System Recovery Settings" window and press the "Next" button.

Select the "Command Line" item.

Enter the first BOOTREC / FIXMBR command

  • The utility records the main boot record (MBR) compatible with Windows 7 in the system partition. This option will solve problems associated with damage to the main boot record, or if there is a desire to remove non-standard code from it. The existing partition table in this case is not rewritten.

Second BOOTREC / FixBoot Team

  • The utility writes to the system section a new boot sector compatible with Windows 7.

We leave by writing an exit and reboot a computer.

3. In principle, these actions must "cure" a computer. But there are also teams if dark clouds continue to thicken over their heads. We enter the BOOTREC / SCANOS command, the hard drive is scanned for operating systems and if any will be found, the appropriate warning will be released. Then the BootRec / RebuildBCD command, this utility Suggested to deposit Windows found in the download menu, agree and enter Y and click ENTER. Windows has been successfully added to the download menu.

4. In addition to the described methods, you can use the BootSect / NT60 SYS command, the main boot code will also be updated. Next EXIT and reboot.

5. If nothing helps (although hard to believe) restore the download environment using the bcdboot.exe utility, it is used to create a system partition or restore the download environment located in the system section. The command line looks like: BCDBoot C: \\ Windows If you have the system installed on another section you need to fix the path in the command, for example, on BCDBoot E: \\ Windows

Thus, we have successfully restored the "bootloader" in Windows 7 and there is no need to drag a computer into the workshop. How to be if there is no mounting disk or flash drive. Download at least this program in advance. Fill it on a disk or USB drive. By the way, remember, we have already had a post about how to create a multi-load flash drive. When you see the black screen, I remember this program, there is a lot of interesting things, including the interpreter of the cmd.exe command line.

This, perhaps, is enough, although the inability to launch the Windows 7 operating system due to a damaged or missing loader can be solved using programs such as Hiren's Boot CD, Paragon Hard Disk Manager, MBRFIX and many other useful things 🙂.

How to Disable Account Controls in Windows 7

MBR (in Russian - Home Downloads) - a specific dataset, code lines, partition table and signature. It is necessary for downloading the operating room windows systems After turning on the computer. There are cases when as a result of various hardware and system failures, the IBC is damaged or erased, which leads to the impossibility windows startup. Such problems decide to restore the boot record of the MBR Windows 7. This article discusses several simple methods that you can restore the record.

A bit of theory

After inclusion computer BIOS. Selects the information carrier from which the download will be performed. At this stage, the device needs to know which partition of the hard disk contains systemic windows files. MBR is a small program that is stored in the first HDD sector and indicates the computer to the correct partition to start the system.

If you incorrectly set the second operating system, the partition table may be damaged and the first Windows start will be impossible. The same sometimes occurs when the electricity is suddenly disconnected. If this happened - you should not despair, the damaged data can be fully restored.

Restoring boot record

In order to restore the MBR, you will need the installation disk from which you installed Windows (or any other). If there is no disc, you can create a bootable USB flash drive with Win7. Algorithm Action:

Automatic recovery

To begin with, it is worth providing the MBR repair standard means from Microsoft. Select "Start Restore". Nothing is required anymore, it will take some time, and the computer will report the completion of the process. Try running Windows. If nothing happens - it means that you need to restore the ICBM manually.

Command line

This path requires entering multiple commands to the Windows command prompt.

  • In the system restore menu, select "Command Line".
  • Now you need to enter "Bottrec / FixMBr". This command is used to record a new MBR compatible with Win 7. The command will delete the non-standard parts of the code, correct damage, but will not affect the existing partition table.
  • Next, enter "bootrec / fixboot". This command is used to create a new boot sector for Windows.
  • Next "BootRec / NT60 SYS". This command will update the MBR boot code.
  • Close the console, restart the computer and try running the system. If the problem is still not solved, you must enter several more commands.
  • Run the console again and enter "bootrec / scanos" and "bootrec / rebuildbcd". With these utilities, the computer scans the hard disk for the presence of operating systems, and then make them in the download menu.
  • Following again, enter "bootrec / NT60 SYS" and restart the computer.

Utility Testdisk.

If you do not have a loading flash drive or disk, you can restore a damaged recording with third-party program. To do this, run another (working) OS. If only one Windows has been on your machine, you have to connect a hard drive to another computer. Working with TestDisk is quite complex, therefore it is recommended to familiarize yourself with the manuals dedicated to this program.

Very often, the cause of the computer's work failure is to damage the boot sector or the main boot record.

It fails to start the computer in safe mode, or in the last successful configuration mode. The computer may not produce errors, or on the screen you will see the following entries:

NTLDR Is Missing. Press Ctrl + Alt + Del to Restart,

Unable to run Windows due to a spoiled or missing file: \\ Windows \\ System32 \\ Config \\ System

How to restore the boot sector and boot record using the recovery console?

For Windows XP:

To do this, in BIOS, select the download from the CD / DVD disk or set the boot priority from the CD / DVD disk. File download starts. After the download is completed, click R - run the recovery console.

Which copy of Windows do you need to log in?

1: C: \\ Windows What copy of Windows should I log in? Enter 1, press ENTER.

A message will appear:

** Warning ** There is a non-standard or invalid main boot record on this computer. When using FixMBR, you can damage the existing partition table. This will lead to all sections of the current hard disk. If there are no problems of access to the disk, it is recommended to interrupt the operation of the FixMBr command. Confirm the recording of the new MBR?

Click: Y.
