Download the bootloader recovery program for Windows 7. Console subsystem of the program. What can be done

Starting a computer involves checking the BIOS of all equipment, and if the self-test is successful, loading Windows. The system boots thanks to the bootloader, in which special data is recorded for this purpose. This data can be damaged at any time and a type error and others may appear. If you see a similar error on the screen, or something similar, but the fact is that Windows does not boot, you need to Windows 7 Boot Loader Recovery. By the way, I wrote about boot record recovery for other systems in the following articles:

Now let's get down to business.

Recovering the Windows 7 bootloader using a recovery disc

You need to get a disk with Windows 7, if you have one, great, but if not, then make a bootable USB flash drive. The version in this case is not important, the bit depth is also not important. Boot from a flash drive. When you see the Windows installer at the bottom left, click "System Restore".

A small window will appear with system recovery options. Select the system that needs to be restored. Click the “Next” button.

And here is a window with the necessary options. First, you can try automatic troubleshooting, this is the very first item called "Startup Recovery". Once you click it, you just wait. The disadvantage of this method is that it does not always work, so we will use manual methods.

Using the Command Line

In recovery options, open Command Prompt. There we will enter the following command:

bootrec/fixmbr

Using this simple command, you can restore the boot record on Windows 7. If this does not help, move on to the next step:

bootrec/fixboot

Both commands are more likely to restore the Windows 7 bootloader. Close the command prompt, restart the computer and see what happens. In fact, the system should boot without problems. If this is not the case, I have prepared some more methods.

Use the command line #Method 2

We enter the following commands again and one additional one:

• bootrec/fixmbr
• bootrec/fixboot
• bootsect /nt60 ALL /force /mbr

Let's try to boot the system.

Editing the boot.ini file

A special boot.ini file is responsible for loading the system. Today we will torture him. Perhaps its integrity was compromised as a result of a virus attack or a simple PC failure, so restoring the bootloader of Windows 7 or another system is a priority.

We will need a bootable USB flash drive with 7 again. Once downloaded, click the “Install” button. Go to the window where you can select a disk to install the system. Press Shift+F10 to run command line.

At the command prompt, enter:

notepad

We will open Notepad, where we need to click “File” and “Open”. In the system disk, enable display system files otherwise you won't see boot.ini.

Edit this file using notepad. There are the following options:

• timeout=10– time to select load operating system(if there are several of them);
• multi(0) And disk(0)– these points should always look like this;
• rdisk(0)– number of the disk where the system partition is located. If you have two disks, then the parameter may look like rdisk(1).

The file itself may look like this, only instead of XP - Windows 7.

In most cases, editing Boot.ini will not be necessary. I also advise you to read about the following errors. There are slightly different methods for bootloader recovery, but they are also suitable for Windows 7.

The Windows 7 boot loader stops working for many reasons - if boot.ini is damaged or you try to install XP along with the “Seven”, after which the latter does not want to boot. This occurs because XP overwrites the Windows 7 MBR boot record. Typically, restoring the Windows 7 boot loader is done standard means systems. You can use another tool, for example, Bootice.

The easiest way to restore the bootloader

If pressing F8 does not open additional ways Startup and Troubleshooter, you will need to use a Windows 7 recovery disk or flash drive. From this drive, you will need to boot your computer into 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 copes with the task, all that remains is to reboot.

If it was not possible to restore the Windows 7 bootloader after XP, use the startup recovery tool, which, along with others, is part of the installation disk or flash drive. Usually these simple ways can handle simple MBR startup problems.

Editing boot.ini

Boot.ini is responsible for starting the system by default. If one of the operating systems is installed incorrectly or uninstalled, its non-working entry will be stored in the same boot.ini. It is located at the root of the system partition, so to edit it you need to configure your computer to show hidden files.

Sometimes boot.ini can be corrupted by a virus or some program could have caused it, after which the OS does not start on its own.

The fix is ​​simple - boot from the LiveCD and edit boot.ini using regular notepad. There are only two sections - boot loader, which controls the boot, and operating systems. There are several parameters to remember:

• timeout=10 - time in seconds during which the user can select an OS to start;
• multi(0) and disk(0) are parameters that must have zero values;
• rdisk(0) - number of the disk with the system partition (counting from zero).

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

Using the command line to restore the MBR sector

You can get into command line mode from the same boot disk or flash drives by opening the system recovery tool and selecting the very last item “Command Prompt”.

1. Enter the command Bootrec and then press Enter, it will appear full list opportunities
2. Write down the MBR sector, for which there is the command Bootrec.exe /FixMbr;
3. After pressing Enter, the computer will notify the user about the successful completion of the operation in the next line;
4. Next, carry out the procedure for writing a new boot sector by entering Bootrec.exe /FixBoot;
5. All that remains is to enter Exit and try to restart the computer.

1. Log in to the command line from the installation disk or flash drive;
2. Enter Bootrec /ScanOs, after which the utility will scan the computer for the presence of an operating system;
3. Write the command Bootrec.exe /RebuildBcd in the next line, the program will prompt you to add all found versions of Windows, including XP, etc., to the start menu;
4. All you have to do is agree with this by pressing Y and Enter in sequence, after which when loading the system you will have a choice of which OS to load - XP or Seven.

You can also fix the problem with the MBR with one more command. To do this, enter bootsect /NT60 SYS at the command line, then Enter. Enter Exit to exit. This will update the main boot code and your systems will appear in the list at boot time.

In case of serious problems, it may not be possible to restore the MBR using the described methods, so it is worth trying to overwrite the files located in the download storage.

BOOTMGR is missing

The computer usually displays this message on a black screen when the MBR sector is damaged or deleted. The reason may not be related to the MBR, for example, if the BIOS settings on the Boot tab have been reset and the system is trying to boot from the wrong disk. But more often than not, it is the bootloader that is to blame, so we will describe how to restore Windows 7 boot.

The Windows 7 disk always has a small 100 MB reserved hidden section, to record OS boot files, including damaged BOOTMGR. You can simply copy BOOTMGR from the installation media and write it to this partition. For this:

1. Open a command prompt from your recovery drive.
2. Enter the diskpart and list volume commands in sequence, after which a list of your disks and the letters that the system has assigned to each of them will appear on the screen. We are interested in the 100 MB reserved partition and the optical drive - drives C and F, respectively, as in the picture.
3. To exit, type Exit and press Enter.

Enter the installation drive letter followed by a colon and the command to copy the bootmrg bootloader to the reserved partition. It will look like this:

• F: and then Enter;
• copy bootmgr C:\ and press Enter;
• Exit, the utility will exit.

If copying to a hidden partition fails, the boot store can be completely overwritten. Restoring the Windows 7 boot loader is performed with the command bcdboot.exe N:\Windows, where N is the drive letter of the OS. After you are informed that the files were created successfully, you can exit the tool with the Exit command and restart your computer.

• write down the line diskpart in the command line, which calls the utility;
• to display all available physical disks, write list disk;
• is selected required disk command sel disk 0, where 0 is the number of the only installed HDD;
• to display all hard drive partitions, enter list partition;
• to select a reserved partition, write the command sel part 1, where 1 is the partition number;
• make it active by typing active;
• exit the application by typing exit.

As a last resort, you can completely manually delete and format the system partition by starting from some LiveCD, and then use the bcdboot.exe command to create the sector again.

Using Bootice

If Windows XP was installed after "Seven", due to the overwritten MBR sector, only XP starts and you do not have the ability to select a system after you turn on the computer. At the same time, both systems are fully functional, and you can return the startup menu very easily, for which you use the Bootice utility:

In the new Bootice window on the left you will see the OS boot list, to which you will need to add the missing “Seven” to Windows XP:

• click "Add";
• in the list that opens, select the line new entry Windows 7;
• on the right side in the upper input field, select the hard drive;
• in the field below, indicate the section with “Seven”;
• click on save basic settings.

The program will notify you that this element has been successfully changed in Boot and you can exit Bootice. The next time you turn on your computer, you can already choose which OS to boot from hard drive- Windows 7 or XP.

Report content

Skills that will help the user restore the Windows 7 bootloader are necessary if the operating system does not start at all or a number of problems arise during the process of turning it on.

The operating system loader is system program, which is designed to launch the OS.

In simple terms, this is a utility with which you turn on your computer.

With the advent of new versions of operating systems, bootloaders also improve. For example, Windows XP boots using UEFI.

Newer versions of the OS (starting from the seventh) use the BOOTMGR system utility during their boot process.

Types of bootloader problems

The most common cause for concern is the following errors:

• When you try to start the system, messages called “Bootmgr is missing” and/or “Non system disk” appear. They occur as a result of damage to the bootloader or master boot record;
• .
  In this case, it is necessary to restore the bootloader if a message from a hacker asking to send money to destroy the virus appears immediately after the user presses the start button on the personal computer or laptop;

Remember! If the operating system has already begun the startup process and errors began to appear only later, this does not indicate a problem with the bootloader. Try turning on the OS in safe mode and troubleshooting any problems (for example, virus software).

Before attempting to set up the boot loader, go to the BIOS and make sure that the system is set to the correct boot order for all hard drives.

If you have two hard drives installed on your computer at once and their startup order is incorrect, problems with the bootloader may occur.

The first in line should be the disk on which the operating system to be launched is installed.

Automatic recovery using USB drive

You need to solve the problem starting with the easiest method.

If you are unable to fix the bootloader using the method below, try the following solution to the problem presented in the article.

To begin the process of solving the problem, take the disk from which the OS was installed.

If you don’t have one, you can restore without a disk - in this case, you need to create a bootable external usb media.

The version of the operating system located on the media must fully match that installed on the computer.

To perform automatic recovery from a flash drive or disk, follow these steps:

• Insert the disk into the drive or flash drive into the slot. Start the computer and in the first few seconds press the F button on the keyboard. This way you will instantly launch the BIOS menu before a problem occurs.
  In the BIOS, change the boot order of the OS components - the disk or flash drive should come first (depending on which device with the OS image you connected to the computer).
  After the boot queue has been set, save all changes and exit the BIOS settings. The OS startup process will begin again, however, now it will boot directly from the image media. The following window will appear;

• At the bottom of the window (Figure 2), find the OS recovery item and click on it. Now you need to select the OS that needs to be restored (if several systems are installed on the computer at the same time);

• After you have decided on the name of the OS whose operation you want to fix, a window will appear with all the available operating system recovery options. To get started, select automatic troubleshooting.
  This method may help, but not in all cases. If the system still does not turn on after such an automatic fix, repeat steps 1-3 again and now select the second option (enabling a previously saved OS state).
  Wait until everything necessary actions will be carried out automatically by the program. If the system boots successfully, the problem is resolved. If not, you should restore it manually.

Restoring OS boot configuration data

OS startup configuration information contains detailed information about the order in which data should be loaded when the computer's operating system is turned on.

Often the OS bootloader fails to complete due to corrupted items in the Boot Configuration Data.

To fix the problem, you need to add new configuration data to the OS bootloader:

A complete configuration update can be performed using the rebuildbcd command.

To perform it, you need to open a command line window in the system recovery options (as in the figure above).

In the line, enter the text “bootrec.exe /rebuildbcd” (without quotes) and press the Enter button to execute the command. The update process may take several minutes.

After its completion, a line about the result of the command will appear in the utility window.

After restoring the data, you should turn off the computer, remove the disk with the OS image from it, configure the standard boot order in the BIOS and turn on the device again.

If all actions were done correctly, the system will start in standard mode.

If after executing the command you receive a system notification that the configuration could not be restored, you need to boot into safe mode.

To do this, enter the command bootrec.exe/safeboot at the command line - it allows you to start the operating system using a minimum number of drivers and third-party utilities that can cause an OS bootloader error.

To view and edit bootloader configuration parameters, run the BCDEdit.exe command:

Recovery using Bootrec utility

If the above methods for restoring the OS do not work, you need to try to fix the bootloader using a system utility called bootrec.

Go to the command line (second instruction of the article) and enter the following command in it:

bootrec/fixmbr– this command allows you to instantly rewrite the bootloader data in the corresponding partition on the hard drive.

Now enter the command bootrec /fixboot to write a new partition for later booting.

The command line window after successfully entering and executing the commands should look like this:

Close the command line, exit the recovery environment, return the boot queue to the BIOS and turn on the OS in the usual way, everything should work fine.

Restarting Windows 7 boot after installing XP

If two versions of Windows OS are installed on your PC at the same time: XP and the seventh version, in most cases a failure will occur when you try to run more than new version systems.

This happens because the XP boot loader does not assume that there are any other boot loaders in the system, so it does not allow you to select and run another OS installed on the computer.

To fix the problem, just return the boot selection using the MultiBoot utility - this is a small program that effectively eliminates the problem of bootloader conflict.

Install the application on your computer and follow the instructions:

1. Check all the necessary boxes in the main window of the utility;
2. Click on the “Run” button;
3. Once the process is complete, restart your computer.

Restoring the windows bootloader.

In this video you will learn about restoring the windows bootloader. If you installed windows 7 on a computer where windows xp was already installed, then xp will stop loading.

Often, after an inexperienced or simply overly self-confident user plays with the computer settings, it begins to produce various errors - even . In most cases, they are easy to fix by simply asking Google the right questions.

But what to do if the system doesn’t even want to boot?

Description of the problem

A black screen and scary white inscriptions plunge inexperienced users into despondency, making them want to immediately format the C:\ drive and install new system. This is not always the smartest thing to do. Let's look at one of the most common errors that prevent the operating system from booting: Windows bootloader corruption. This error makes itself felt with a black screen and a system message:

Bootmgr is missing Press Ctrl+Alt+Delete to restart

This inscription is very deceptive; it cannot be perceived directly. Knowledgeable English language people can easily translate “The boot manager is missing, press Ctrl+Alt+Delete to reboot.”

Let's figure out what these words mean. For convenience, we will split this message into two parts:

• There is no download manager. This does not mean that all information has been deleted from the disk or that the hard drive itself is missing. The system means that it cannot read information about where to boot the system from. It can’t, it means it doesn’t exist - that’s computer logic.
• Press Ctrl+Alt+Delete to reboot. A classic of the genre - by pressing these keys, you simply restart the computer, but the error will remain. This can be repeated ad infinitum.

From this we conclude: everything is not so bad, because the problem can be fixed programmatically. To do this we need to do special procedure- restoring the Windows 7 bootloader. This can be done in two ways.

Recovering the bootloader using System Restore

To restore using this method, you will need a boot disk ( installation disk Windows). Then simply follow the algorithm:

Let's look at them separately:

System utility Bootrec. This program is very functional, but its main purpose is to overwrite the master boot record on the system partition. That is, it should only be used when the boot record exists, and you just want to remove unnecessary code from it.

You can run this program by writing the command “Bootrec.exe” into the command line. After this, the utility will display a list of keys with which it works, and you select the one you need and write: Bootrec.exe “needed key”. Just remember that keys are written separated by a space.

System utility BCDBooT. This program is used to create or restore a boot record. That is, it needs to be used when it is damaged or completely missing.

To create a boot entry, write the command “bcdboot.exe” into the line. Then, separated by a space, write the path to your operating system. For example "C:\windows". The complete command will look like this: "bcdboot.exe C:\windows".

Recovering the bootloader without a boot disk

This method is almost identical to the first, except that you do not need a boot disk to implement it. This is very convenient, but does not always work.

To restore the Windows bootloader using this method, you need to do the following:

• After turning on the computer, press the F8 key before loading the operating system.
• If you did everything correctly, a window will open additional options downloads.
• Select the first option, “Troubleshoot your computer.”

Restoring the Windows 7 boot loader - performing steps to restore the operating system after problems occur when loading Windows. Due to a system failure, the user may lose data and personal files located on the computer.

At one point in time, the operating system will not be able to boot on the computer. Various messages (not always in Russian) appear on the screen, indicating a problem loading Windows.

The main causes of problems with Windows boot loader 7:

• user actions: attempt to use hidden system partitions, incorrect changes to boot files using EasyBCD, etc.;
• system failure;
• exposure to malicious software;
• the appearance of bad blocks on the computer’s hard drive;
• operating systems are installed on the computer in the wrong order;
• hardware problems.

The problem with the bootloader must be solved, otherwise you will not be able to use Windows, because the system will not start on the computer. Problems can be resolved in a radical way: again on the PC.

If there is one created by the system tool, or using third party programs you need to restore from backup Windows image created in advance. Many users, unfortunately, do not remove due attention backup systems, so these methods will not suit them.

How to restore Windows 7 bootloader? To restore operating system boot files, use the built-in using Windows: automatic startup recovery, as well as using the BootRec and BCDboot utilities included in the operating system, launched on the command line.

Before using operating system tools, you need to know the hard drive layout. Modern computers have a GPT hard drive layout style and a new BIOS - UEFI, and in Windows times 7, MBR partitioning was used on the disks, and now outdated BIOS. On some computers, Windows 7 64-bit is installed on UEFI and GPT drives, and in general, Windows 7 PCs use MBR (Master Boot Record) partitioning.

In this article, we will look at instructions on how to restore the bootloader in Windows 7 using system tools: first, we will perform an automatic recovery, and then we will try to restore the bootloader from the command line.

To perform bootloader recovery operations, you will need either an installation DVD with the operating system, or a bootable Windows flash drive 7. Bootable media is needed to be able to boot to personal computer Windows RE Recovery Environment ( Windows Recovery Environment), with which you can try to solve the problem with the inability to start the system.

Perform Windows 7 recovery automatically using the system tool

The easiest way: automatic recovery of the boot partition on the hard drive using the operating system. This action occurs without user intervention; you only need to boot onto the computer from the boot disk.

Immediately after starting the computer, using the keyboard keys you need to enter the boot menu ( Boot Menu) to select external device For loading: DVD disc or USB flash drives. Which keys to press depends on the hardware manufacturer, check this in advance. Another way: you can enter the BIOS and set the boot priority from the connected device there: USB storage or DVD disc.

In this example, I am using a Windows 7 installation disk, all actions with bootable flash drive are performed in a similar way.

In the first window of the program Windows installations click on the “Next” button.

In the window asking you to start installing the operating system on your computer, in the lower left corner click on “System Restore”.

In the “System Recovery Options” window that opens, a search will begin. installed systems.

After a while, a message will appear stating that problems have been detected in the computer's boot settings.

Click on "Details" to view a description of the fix.

To run automatic troubleshooting of system boot problems, click on the “Fix and restart” button.

After restoring the bootloader, the operating system Windows system 7 will boot on your computer again.

Automatic troubleshooting using system tools can be started a little differently:

1. In the "System Recovery Options" window, enable the option "Use recovery tools to fix problems when Windows startup. Select the operating system to restore" and then click on the "Next" button.

1. In the window for selecting recovery tools, click on “Startup Recovery”.

1. Wait for the operation to automatically resolve problems that are preventing the system from starting to complete.

If the problem is not automatically resolved, then move on to the following methods, in which the user will have to manually enter commands in the Windows Command Prompt.

Restoring the Windows 7 bootloader using the Bootrec utility

The next method involves restoring the Windows 7 boot loader via the command line. For this we use the Bootrec.exe utility. This method only works with disks that have a Master Boot Record (MBR).

From the boot disk you need to enter the Windows Recovery Environment using the method described above.

In the System Recovery Options window, click on the Command Prompt option.

The Bootrec.exe utility uses the following basic commands:

• FixMbr - The option writes the master boot record (MBR) to the system partition of the disk, compatible with Windows 7, does not overwrite the existing partition table
• FixBoot - using the command, a new boot sector that is compatible with Windows 7 is written to the system partition
• ScanOS - searches all drives of installed Windows 7 compatible systems, displaying entries that are not in the system configuration store
• RebuildBcd - searches all drives of installed Windows 7 compatible systems, selecting systems to add data to the boot configuration store

The FixMbr command is used to fix the master boot record, as well as to remove incorrect code from the master boot record.

The FixBoot command is used under the following conditions: the boot sector is damaged, the boot sector has been replaced with a non-standard boot sector, an earlier boot sector was installed on the Windows 7 computer Windows version(Windows XP or Windows Vista).

The ScanOS command searches all drives for operating systems compatible with Windows 7. As a result, all entries related to other operating systems installed on the computer that do not appear in the boot manager menu will be displayed.

The RebuildBcd command allows you to detect and add boot configurations installed on the system computer to the storage. This option is used to completely rebuild the system boot storage configuration.

In the command line interpreter window, enter the command (after entering commands in the command line, press the “Enter” key):

Bootrec/fixmbr

If the problem persists, you may need to enter the following command:

Bootrec /fixboot

The remaining commands are used if multiple operating systems are installed on the computer.

Close the Command Prompt, and in the System Recovery Options window, click the Restart button.

How to restore the Windows 7 bootloader from the command line using the BCDboot utility

Using the bcdboot.exe utility, you can restore the Windows 7 bootloader on computers with MBR or GPT hard disk partition styles.

Boot from the removable device, go to the window with the choice of system recovery method, and then launch the command line. Another option: in the very first window, press the “Shift” + “F10” keys on your keyboard to enter the command line window.

In the Command Prompt window, enter the command to launch the DiskPart utility:

Diskpart

To display information about your computer's drives, enter the following command:

List volume

We need to find out the drive letter (volume name) on which the operating system is installed.

The volume name (drive letter) in Diskpart may be different from the drive letter in Explorer. For example, in my case, in Explorer the system partition has the letter “C”, and in diskpart it is designated by the letter “E”.

To exit diskpart utilities enter:

Bcdboot X:\windows

In this command: “X” is the drive letter on which the operating system is installed. In my case, it is the letter "E", you may have a different volume (disk) name.

Close the command prompt.

In the System Recovery Options window, click the button to restart your computer.

Conclusions of the article

If problems occur with the Windows 7 boot loader, you must restore the system boot files by booting your computer from the bootloader. Windows disk. You can restore damaged or missing files using operating system tools: automatic troubleshooting of Windows boot problems, using the Bootrec and BCDboot utilities, launched from the command line in the recovery environment.
