What to do bootmgr is missing press ctrl alt del to restart. Error bootmgr is missing

I get this error when loading operating system, I can’t do anything with it, I correct it as it’s written everywhere, I boot from installation disk Windows 7, select system restore, then command line, diskpart commands and list volume I determine the letters of the drive (D:) and the system (C:) I write D: then copy command bootmgr c:\ and again I can’t boot, it’s some kind of nightmare, save me people. Anton.

BOOTMGR is missing in Windows 7

You will never guess how we corrected the situation, the fact is that Anton did everything right. I came across this error quite often and I want to say that a deleted or damaged operating system boot loader is not always to blame.

Note: Friends, if this article does not help, try our other two articles - they describe other ways to restore the boot of your operating system.

There are several other reasons related to hardware, for example, often on a computer that is brought in for repair with this malfunction BOOTMGR is missing in Windows 7, the settings of the Boot tab in the BIOS disappear. This means that the bootloader is alive and unharmed on the disk with installed Windows 7, but since the computer is trying to boot from the wrong hard drive, we get a similar error. What can I say, let's go specific examples We'll see how we deal with this problem.

  1. Recovering the Windows 7 bootloader using startup repair.
  2. Restoring the bootmgr bootloader in Windows 7 using command line.
  3. At the end of the article we will solve the error problem BOOTMGR is missing in Windows 7, by changing the settings in the BIOS

First of all, let's try to restore Windows boot loader 7, to do this, at the very beginning of loading, press the F-8 key, a menu should appear Additional download options,

in it we must select the first item Troubleshooting your computer. If this menu no, it means we have deleted a hidden partition containing the Windows 7 recovery environment, in this case we must use either the installation Windows disk 7. We boot from the installation disk of the seven, in the initial phase of booting the computer, when prompted to boot from the disk “ Press any key to boot from CD…", press any key on the keyboard, otherwise booting from the disk will not happen


Happening quick analysis problems that interfere with the normal boot of Windows 7, the recovery environment offers to fix problems detected in the boot parameters of this computer automatically. Click on "Fix and restart". In most cases, such simple actions will result in Windows 7 booting being restored.

and select Startup recovery, Windows 7 will run the Startup Repair tool and, if it finds damaged files, replace them. If the number did not go through, read on.


Second method: in the window System Recovery Options choose Command line,

Attention: So that you can better understand what I will do next, I will show you the Disk Management of my operating system.

Everything is as usual, the operating system files are located on the C: drive, but you see this hidden partition without a drive letter, with a capacity of 100 MB Reserved by the system, so, it is in this section that all Windows 7 boot files are stored, including the operating system loader file bootmgr, but it is not there now or it is damaged, which is why you and I are getting an error when loading " BOOTMGR is missing. Press Ctrl+Alt+Del to restart".

Our goal is to copy the bootmgr file from the Windows 7 installation disk to this partition. Let's do this simple operation, but first let’s decide on the drive letters, since yours may be different.

Note: Friends, now we will work with the command line of the recovery environment. I will give you the necessary commands, but if it is difficult for you to remember them, you can create a cheat sheet - a text file with a list of necessary resuscitation commands and open it directly in the recovery environment. This will make your work much easier.

We type in the command line

diskpart

list volume

As you can see, in the command line the drive is assigned the letter F:, and my hidden partition Reserved by the system, volume 100 MB, Windows 7 recovery environment assigned the letter C: (operating system files with Windows folders And Program Files located on drive D:).

Enter exit

and exit diskpart.

In the command line we enter F:, with this command we enter the Windows 7 installation disk.

copy bootmgr C:\ that is, copy the bootmgr loader from the Windows 7 installation disk to the hidden partition Reserved by the system C: . That's all.

Friends, the hidden partition “Reserved by the system” with a volume of 100 MB is not always created when installing Windows 7, in rare cases it may not exist, in this case copy the bootmgr file directly to the root of the disk with the operating system files.

If, when copying the bootmgr file, you get an error stating that you don't have enough rights, then try to completely overwrite the storage BCD downloads.

In Windows 7 Recovery Environment, determine the drive letters.

Enter the command:

diskpart

list volume

Drive letter assigned F:, and the hidden partition Reserved by the system, volume 100 MB, Windows 7 recovery environment assigned a letter C: . This means that the operating system files with the Windows and Program Files folders are on the disk D:.

We lead the team

bcdboot.exe D:\Windows

This command will overwrite the entire BCD boot store (the contents of the Boot folder in the System Reserved section) and the bootmgr file for Windows 7 located on the D: drive.

Success. The download files have been successfully created.

If you get any errors again, you can boot from the LiveCD and delete all the contents hidden section Reserved by the system, volume 100 MB, and then recreated again by a command already known to you.

Troubleshooting BOOTMGR is missing in Windows 7 from our reader. Anton, like me, has three hard drives on his computer, only one of them has Windows 7 installed, which means the computer must boot from it. Let's go into the BIOS and look in the BOOT tab, item Boot Device Priority

Is it loading from the right disk, of course not, the Western Digital hard drive comes first,

on which only personal data is located, and where is the MAXTOR hard drive with Windows 7 installed, let's look. Why the settings in the BIOS were broken, there are many reasons, for example a crash CMOS battery or the computer was turned off incorrectly. Fixing the BOOTMGR i s missing error, press Esc on the keyboard and go to the tab Hard Disk Drives

it is in it, in the presence of several hard drives The one from which the computer needs to boot the operating system is determined.

We put the MAXTOR hard drive in first place

What else can you do if there is an error?BOOTMGR is missing in Windows 7

Recently, one of my friends brought me a system unit with a complaint that the two operating systems installed on different hard drives Windows systems 7 and Windows 8 do not boot, giving the error BOOTMGR is missing on boot in Windows 7.

I had to boot the computer from boot Acronis disk Disk Director. As you can see, there are two hard drives, the first is Disk 1 with Windows 7 installed, and the second is Disk 2 with Windows 8 installed. Pay attention to the two red flags that mark the wrong partitions. Why? A red flag means that this section is active and the operating system should be loaded from it.

The error is that on both hard drives the first hidden partitions System Reserved should be marked with a red flag, that is, they should be active. On Windows 7, the volume of such a partition is 100 MB, and on Windows 8, 350 MB, these sections have the attributes: System. Active and it is on these partitions that the boot store configuration files (BCD) and the system boot manager file (bootmgr file) are located. And it turns out that these attributes are carried by other sections. Because of this, Windows 7 and Windows 8 will not boot.

Note: You can make a partition active using the command line (see the end of the article), or you can use the program Acronis Disk Director.

What should be done? Select the first hard drive 1, right-click on the first System Reserved partition and select “Mark as active”

The System Reserved volume will be marked as active. Click OK.

We do the same with Disc 2. Acronis program Disk Director works in pending operation mode, for the changes to take effect, click the "Apply pending operations" button

active and the section becomes active.

Hello.

The other day I encountered a rather unpleasant error “BOOTMGR is missing...” that appeared when I turned on the laptop (by the way, Windows 8 was installed on the laptop). We managed to fix the error quite quickly, simultaneously taking several screenshots from the screen to show in detail what to do in case of a similar problem (I think that more than a dozen/hundreds of people will encounter it)…

In general, such an error can appear for several reasons. reasons: for example, you install another one on your computer HDD and do not make the appropriate settings; resetting or changing BIOS settings; improper shutdown of the computer (for example, during a sudden power outage).

The following happened to the laptop on which the error appeared: during the game, it froze, which angered the user; they did not have enough patience to wait a little, and they simply disconnected it from the network. The next day, when I turned on the laptop, Windows 8 would no longer boot, showing a black screen with the error “BOOTMGR is...” (see screenshot below). Well, then the laptop ended up in my possession...

Photo 1. Error “bootmgr is missing press cntrl+alt+del to restart” when turning on the laptop. The computer can only be restarted...

Fixing the BOOTMGR error

To restore the laptop's functionality, we need a bootable USB flash drive with the OS. Windows version that you had installed on your hard drive. To avoid repetition, I will provide links to the following articles:

1. Article on how to create bootable USB flash drive:

2. How to enable booting from a flash drive in BIOS:

Then, if you successfully booted from the flash drive ( in my example, Windows 8 is used, with Windows 7 the menu will be slightly different, but everything is done in the same way) - you will see something like this picture (see photo 2 below).

Photo 2. Beginning Windows installations 8.

There is no need to install Windows 8; in the second step, we should be asked what we want to do: either continue installing the OS, or try to restore the old OS that was on the hard drive. Select the “recovery” function (in the lower left corner of the screen, see photo 3).

Photo 3. System recovery.

In the next step, select the “OS diagnostics” section.

Photo 4. Windows Diagnostics 8.

Go to the additional parameters section.

Photo 5. Selection menu.

Now just select the function “ Startup Repair - Troubleshoot problems that prevent Windows from booting«.

Photo 6. Restoring OS boot.

In the next step, we are asked to specify the system that needs to be restored. If Windows OS is installed on the disk in the singular, then there will be nothing to choose from.

Photo 7. Selecting an OS for recovery.

But this is not so important, in most cases, with such an error and after such a “recovery operation” - after restarting the computer, it will work (do not forget to remove the bootable USB flash drive)! By the way, my laptop started working, Windows 8 was loaded as if nothing had happened...

Photo 8. Restoration results...

Another reason for the BOOTMGR is missing error The problem is that the hard drive for booting was incorrectly selected (perhaps the BIOS settings were accidentally lost). Naturally, the system, not finding boot records on the disk, gives you a message on a black screen that “error, there is nothing to load, press the following buttons to reboot” (however, it displays in English)…

You need to go into the BIOS and look at the boot order (usually there is a BOOT section in the BIOS menu). To enter the BIOS, buttons are most often used F2 or Delete. Pay attention to the PC screen when it boots, there are always buttons for entering the BIOS settings.

Photo 9. Button to enter BIOS settings - F2.

Next we are interested in the BOOT section. In the screenshot below the first thing is loading from a flash drive, and then only from the HDD. In some cases, you need to change and put booting from hard drive first HDD(thus correcting the "BOOTMGR is..." error).

Photo 10. Laptop boot section: 1) loading from a flash drive comes first; 2) on the second boot from the hard drive.

You might find it useful article about resetting BIOS settings (sometimes it helps):

PS

Sometimes, by the way, in order to fix such an error, you have to completely reinstall Windows (before this, it is advisable to save all user data from the C: drive to another partition of the disk using an emergency flash drive).

That's all for today. Good luck to all!

Many people have encountered a situation where the computer refused to boot and gave an error:

BOOTMGR is missing. Press Ctrl+Alt+Del to reboot

or its Russian version:

Bootmgr is missing. Press Ctrl+Alt+Del to restart

What does this error mean?

The error means that the system cannot detect a working Windows boot loader on the media that is specified in the BIOS boot priority.

Possible causes of the BOOTMGR is missing error and solutions

1. The bootloader is damaged or missing.

Solution: You need to perform a bootloader recovery.

Insert the installation disk into the drive Windows DVD(or USB disk).

Attention! It is very important that you use the same installation distribution, as when installing the system. If you have Windows 7 Ultimate installed, you will not be able to run System Restore from the Windows 7 Home Basic disc.

Boot from the installation disk. Press any key when you see the message Press any key to boot from CD or DVD:

In the next window, click Further:

Wait for the system to detect everything installed copies Windows on hard drives:

The recovery program will search for problems and attempt to repair normal loading Windows. While you see the following window, just wait:

Click the button Ready to restart the computer:

If Windows does not start to boot normally, repeat the procedure again. Sometimes, the recovery program solves the problem the second time. If this method fails to restore normal system loading, proceed to the next reason.

2. The 100 mb boot partition is not active.

In some cases, there may not be a hidden 100 MB partition. For example, if Windows 7 was installed on an existing partition after Windows XP.

Solution: make the section active.

Execute the following actions: Launch Command Prompt and type the following commands:

Diskpart - run the utility for working with disks and partitions list disk - display a list of disks sel disk 0 - select the disk on which Windows is installed list part - display a list of partitions (i.e. partitions) sel part 1 - select boot partition active - make the selected section active

Options disk 0 And part 1 imply that your computer has one hard drive, and the Windows boot loader is on the first partition (i.e. logical drive). This is the most common situation. However, it could be different.

When you see the message Section marked as active, close the console window and click the button.

Now let's look at a few more frivolous, but probable causes Problems.

3.The hard drive priority settings in the BIOS have gone wrong.

If the CMOS battery is dead or has recently been removed, the settings may have been lost. Thus, the disk with the bootloader can be in in perfect order, and the system is simply trying to boot from the wrong disk.

Solution: Enter BIOS, in Settings boot devices Install the hard drive as the first device.

Setting the boot order on the motherboard Gigabyte board for socket LGA775 manufactured in 2010:

In the parameter First Boot Device indicate Hard Disk:

Then, go to the section Hard Disk Boot Priority:

and first install the disk on which the boot partition is located:
(The picture shows that a 180GB SSD drive is installed under the first number, and the other two data drives have a lower boot priority)

Setting the boot order on a 2011 HP laptop:
(The picture shows that the hard drive is at the top of the list)

Related advice! To avoid such situations, try to connect to the SATA0 connector exactly the hard drive that contains the boot Windows partition. In this case, if BIOS settings and go wrong, then the probability of changing the loading order is minimal.

4. A hard drive or flash drive is inserted into the computer’s USB port.

If the BIOS is set to priority loading from USB, the computer can boot normally without USB disk. However, if a storage device is connected to USB, the system may try to boot from it and subsequently display error BOOTMGR is missing. Action: Disconnect all USB drives and flash drives and restart the computer.

Hello, friends! In this article I will tell you how to deal with the error. BOOTMGR is missing in Windows 7. This error occurs when the bootmgr file is damaged or missing on the active partition (the active partition is the one from which the boot occurs), as a result of which the system cannot boot. Our task is to rewrite this file with a working one from the distribution kit. The distribution package in the form of an ISO image must be written to a flash drive or disk. As a result, we will have a bootable USB flash drive or a bootable (installation) Windows 7 disk from which we will copy the file bootmgr. Then you need to boot from the created disk or flash drive and overwrite this file. This is in brief. Now more details.

Request. Please read the entire article, especially the conclusion. There is a nuance with the AutoUnattend.xml file in the image due to which it may not be possible to enter the recovery environment and, accordingly, restore loading Windows 7.

Before you go into the wilds you need to try to call Additional options downloads by clicking F8 several times when you turn on the computer (as when entering safe mode). If you have the “Troubleshoot your computer” item, then use it to immediately go into the recovery environment and go to point 1 of this article

  1. Download Windows image 7 . The easiest way is to download it via torrent. You can find the desired torrent tracker with Windows 7 images by searching in Google or Yandex using the phrase “Windows 7 download”. You can read and see how and where to download the original image of Windows 7.
  2. Write to a flash drive or disk downloaded image and thereby turning this media into a bootable one. How to do boot disk— . How to make a bootable USB flash drive - . You can also use the article about burning an image to disk using Ashampoo or using Windows 7.
  3. Boot from a flash drive or disk. How to boot from a flash drive - . How to boot from a disk - exactly the same as from a flash drive, only instead of a flash drive in the BIOS (in the BOOT tab) you need to install a read drive optical disks to first place.

The preparatory stage is over.

Team select isk 0- choose required hard disk. (substitute your number if you have several)

Team list partition— view the number of partitions on the selected disk

Team select partition 1— select the section that you want to make active. Typically this is a partition with a size of 100 MB. If you do not have a 100 MB partition, choose your C drive based on the size.

Team active— make the selected section active

Team exit— exit the DISKPART utility

Close the command line window and restart the computer.

Conclusion

Previously, when I saw the BOOTMGR is missing error, it was easier for me to reinstall the operating system. I usually don’t have all the data system disk and in the clouds (Dropbox, Google Drive and Yandex.Disk). So there are no problems with reinstallation. It's a shame it's only 2 hours. Also, by booting from the installation disk, you can restore your computer using restore points or restore a complete system image (if, of course, you previously created one) by selecting the appropriate items in the System Recovery Options window. IN general environment recovery is a power that needs to be used.

There is one more nuance, without mentioning which you may remember me “with a kind, quiet word.” If you, like me, use builds from Idimm, then you will not be able to enter the recovery environment. The reason for this is the file AutoUnattend.xml. This is an answer file for a simplified Windows installation. IN in this case it just gets in the way. The solution is to delete this file from the image and save the image again. The problem is that editing ISO images requires paid software, which not everyone has. I also don’t have this paid software, so I had to download another Windows 7 image and burn it to a USB flash drive.

And the very last nuance. I have a 32-bit system. On virtual machine A 32-bit system is also installed. And, I was unable to use the Windows 7 64-bit image for Windows recovery 7 32-bit. The result is the following

Along the way, you need to have a 64-bit system installed on real hardware. In general, try restoring Windows 7 32-bit with a Windows 7 64-bit disk. I hope it works out. If the bit depths are the same it will work.

During the launch of the operating system Windows 7 and later versions, unexpected failures occur that “spoil” the overall popularity of the OS. Most often, for some reason, the “seven” may not start, despite the fact that there is no damage. During startup it may appear Bootmgr is missing. What to do with Windows, in this article we will try to understand these reasons.

Something like this appears on the user’s screen:

What does this entry mean? Is it possible to solve this issue independently, without the help of specialists?

An entry appearedBootmgr is missing. What to do in Windows 7

First, you need to decide what caused the appearance of the ill-fated recording.

  • Your computer has bad sectors hard drive, as well as non-working cells of the computer SSD. In most situations Bootmgr recovery possible without the intervention of specialists;
  • Perhaps the PC spontaneously turned off or you accidentally pressed the “Reset” key during the reboot process;
  • Viruses have become active on a personal computer; this phenomenon is extremely rare;
  • The user uses it ineptly installed utilities which lead to system failure.

There are several ways to solve the problem Bootmgr how to remove on your PC. Let's try to solve this problem with little expense.


- “bootrec.exe /FixMbr” – MBR entry that will redirect to the system partition;

- “bootrec.exe /FixBoot” - creating a special boot entry on the existing system volume of your PC.

  • Now all that remains is to restart the computer and turn it on again.

Perhaps there is a general stalemate when none of the above actions solves the problem of using Bootmgr is compressed in a given situation for the user. The most optimal, according to computer specialists, would be to perform the operation using the command line and the command bootrec.exe with the "RebuildBcd" attribute algorithm in effect.

A full scan of the operating system of the personal computer will be carried out. If during the scanning process a list of “useful” programs for the “seven” is revealed, the program will offer to download to a special attribute of the download list.

There is a recordingBootmgr is missing. what to do in Windows 10

If you have tried all of the above steps and nothing really helps you, you can go to extreme measures. Let's try to reserve old folder BCD, which is responsible for starting your personal computer during operation and we create a new Bootmgr when installing from a flash drive directly to your Personal Computer(PC). note that further actions with this command you must follow the chain indicated below.

In some cases, the user does not know what the entry means Bootmgr is compressed. Let's try to explain the main criteria for this function.

  • The device you are using to run the OS is not system unit. We disconnect all existing flash drives, phones, mobile devices, disks, including external hard disks and begin to forcefully reboot the OS.
  • We check the basic BIOS settings, which indicate the priority for booting the computer. It is possible that the disk, which in this case is not the system one, starts to load first by accident. Check also through BIOS or special utility whether your operating system sees the hard drive (this phenomenon may be sudden on a PC).
  • Let's try to reconnect the HDD cable; it may fail due to unreliable contact of the cable with the PC. Most likely the cable is bent and the signal is not reaching the motherboard.

The most critical type of computer failure, which allows you to understand what Bootmgr is missing means, is the banal absence of an operating system on your computer. Perhaps you spent full formatting, and your computer decided to show its “character” and completely confused you. We try to additionally restore the OS or the corresponding partition to computer technology. As a last resort, try to check if the hard drive on your PC is damaged.
