Last time Windows users 7 left a lot of feedback about the fact that a kind of glitch occurs during the startup process operating system. This failure appears as an error with the following content: “Bootmgr is missing. Press Ctrl Alt Del to restart." The notification indicates that the OS boot file was not found. To fix the problem, you need to follow some steps that we have outlined below.
But first, you need to briefly describe the current situation. When the computer is turned on, the search is activated on the hard drive (hereinafter referred to as the HDD). software responsible for loading the operating system. Sometimes access to this program becomes impossible due to its possible corruption. The bootmgr is missing error can occur due to several reasons:
- firstly, a failure in the power supply system;
- secondly, incorrect shutdown of computer equipment;
- thirdly, incorrect actions in bios;
- fourthly, the virus.
Effective methods to fix the problem
There are three ways out of this situation:
- check and make sure that the boot disk is used in Bios;
- automatic recovery of the boot loader for Windows 7;
- fixing the "bootmgr is missing" problem using command line.
Checking Bios settings
Take this step if you have at least two hard drives installed on your computer. We are talking about physical hard drives, and not about partitions C, D, E, etc. If you have only one hard drive installed on your computer, then feel free to proceed to the second method of solving the problem. But be that as it may, remove any storage media (flash drives, external hard drives) from the computer. Then restart your PC.
Sometimes a problem arises when, completely randomly, the wrong drive is found in the Bios settings. It is necessary to double-check which disk is being selected. If it is incorrect, then try to replace it with the correct disk and make it active. Then restart your computer.
Automatically fix bootloader problem
The positive thing is that Microsoft has developed a specific recovery environment that makes it possible to eliminate many problems with the operating system, including the bootmgr is missing error. In order to launch it, you should constantly press “F8” until the notification appears until you see the corresponding menu.
If this does not happen, you need to find a recovery disk or flash drive that is current Windows versions. Download from your existing device. When the notification appears: “Press any key to boot from CD or DVD,” enter a key. If you do not do this, the download will begin to be replayed from the hard drive, which will again lead to the bootmgr is missing error. Without completing the installation, select the “System Restore” request at the bottom of the page.
Following this, the recovery utility will perform a diagnostic test hard drive and will start automatic search possible problems. Then you need to accept the troubleshooting and restart your computer.
If after the work done, you do not see any qualitative changes, then you need to resort to re-booting from the installation flash drive, select “System Restore”. When a list of available operating systems appears, select the one you want installed Windows and click Next.
Click on “Startup Repair”.
When will the successful Windows startup, then this will mean that the “bootmgr is missing” problem is solved.
Troubleshooting using the command line
The current bootmgr is missing treatment method is a little more complicated than the previous ones, but it is the most effective. Load the recovery environment, click “Command Prompt”.
During the installation process of Windows 7, a specific hidden 100 MB block is created, which is reserved by the operating system. In loaded Windows 7, it is not designated by a letter (like other drives C or D, E or F). Despite this, the partition you create is very important because it contains a miniature program responsible for booting the system, containing bootmgr. When problems occur with this file or when it disappears, a known error is generated. Therefore it is necessary to restore it. This can be done by transferring it from the installation device.
It is possible to perform a similar step via the command line. Simply put, a black window you recently launched. First, carefully examine the disks and find out where and where you will have to transfer them. important file. After all, the letter names of the drives may be different on different devices.
- enter: diskpart;
- after that, write: list volume;
- Keep an eye on the partition with a total volume of 100 MB and consider what letter it belongs to.
Important! In our picture containing the sample, the corresponding disk is located under the letter C.
In the same way, CD/DVD-ROM is limited to the letter “F”. "D" stands for data disk.
After this, in a clear sequence, perform the following actions:
- Complete the diskpart request: exit.
- Make the transition to a CD/DVD-ROM disc. In our sample it is "F": F.
- Copy the bootmgr file to a small disk. In our picture “C”: copy bootmgr C:\.
After this, a message should appear indicating that one file was successfully copied.
However, it often happens that after recording the current OS on a previously partitioned disk, it is impossible to find the hidden 100 MB section. In such circumstances, you need to transfer the bootmgr file directly to the data disks. In order to simplify the task of indicating the location of the required file, and also to prevent subsequent occurrences of the “bootmgr is missing” error, copy it to disk. In the example from our picture, we are talking about device D. Thus, you have to perform the following action: copy bootmgr D:\.
Restart your PC. When no changes have occurred, access the command line again using the following action: bootsect /nt60 All.
Restart your computer. When the bootmgr is missing error exists, the disk is not marked as active.
Making the disk “Active” using the command line
The disk with the boot file must include bootmgr and also be listed as active. If it is in an active state, then it is, in principle, possible to boot Windows from it. If the wrong disk is considered active, the system boot result will henceforth be “incorrect”.
Restart the command line:
- Enter the already known ones: diskpart and list disk;
- A list will open in front of you containing hard drives. From it, select the disk storing the operating system. Take this step depending on the size of the disks. If there is only one disk installed on your computer, select it using the action: select disk 0 or 1.
- After that, enter a query to view all its sections: list partition;
- Look for the required section of 100 MB in size. If you do not find a small section, select the first or second section, taking into account which disk Windows was installed on. Decide on the section number: select partition 1 (2), and also activate the section: active, then click exit. Before making an exit request, a notification like this should appear: “The section is marked as active.”
- Restart your computer.
The problem has been fixed. Now you know what to do and how to solve the bootloader problem. Work with pleasure!
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 hard drive 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 OS; in the second step, we should be asked again 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 rebooting 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 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 to do is boot 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 everyone!
BOOTMGR Error is missing in Windows 10. What should I do?
So, today you will learn about How to fix the “BOOTMGR is missing” error in Windows 10 and more earlier versions, in the fastest and most convenient way.
BOOTMGR is missing error in Windows 10
If your Windows 10 PC is experiencing the "BOOTMGR is missing" error, you are not alone. If the problem is not hardware related, you can fix it with relative ease as long as you have a Windows DVD. And even if you have boot disk For Windows boot 7.
So I think you all know how to boot from your Windows disk, Restart your computer.
On the POST screen, look for the option “Something like “Press F12 for Boot Settings” or “Press Del to enter BIOS Setup.” Look for him. If you have Boot Set installed.
Then enter it and select "Select to boot" from any Windows bootable media. (In my case it was USB).
Now, once you boot from the Windows bootable media, you will find the Windows 7 or Windows 10 installation screen.
Select " Language settings" and click " Next». 
On the next screen, you will find the Install Now option. See in the bottom left corner, you will find the "Computer Repair" option. Click here.
The installation process will try to find the system installation directory. If there is more than one in the list, select the correct one and then click the button again Next».
Now, in the field " System Recovery Options", click on the first link " Startup Recovery».
The installation process will automatically repair the system and then prompt you to reboot.
And now it had to be repaired.
Another way to fix BOOTMGR is missing error in Windows 10

Bootrec /fixboot [Space after bootrec]
At this point you should be able to restart your computer, remove the DVD and everything should work.
If any other problems persist, please contact me via private message.
By the way, we have already talked about what to do if the SVCHOST.EXE process loads the system.
If you have questions about the topic " BOOTMGR is missing error in Windows 10"- write them in the comments. Also, before writing your comment, please indicate which version of the operating system you are using and after what actions this error appeared in the system.
Problems with the computer always spoil the mood of users. But it’s one thing for the browser to crash due to a plugin problem, and another for Bootmgr is missing. What to do in this case is not always even imagined experienced users. Today we will tell you what this error is, why it appears, and how to fix it.
What is it?
In general, the appearance of such a message during boot is a very serious and bad signal, indicating a problem with the boot area of the hard drive. As a rule, this happens either due to the actions of viruses, or (much more often) due to the excessive curiosity of the users themselves who experimented with partitions. Sometimes a similar situation occurs after an emergency shutdown due to a power outage.
Important! In the latter case, you can really start to worry seriously: standard spindle disks in the event of an emergency stop do not always have time to park the read heads. As a result, deep (relative to the microscopic level, of course) cuts remain on the surface of the magnetic plate. In this case, the message Bootmgr is missing will also appear. What to do? Unfortunately, in this case, only replacing the hard drive will help. However, we will continue to talk about simpler cases.
By the way, on which system is Bootmgr is missing most often? Windows XP! The reason is both in the “honorable age” of the hard drives used on such computers, and in some system features inherited from their “ancestors”.
If an inexperienced person often assumes that the hard drive will fail, which results in the purchase of a new hard drive and the complete loss of all data. Fortunately, everything is not so serious: you can completely overcome Bootmgr is missing. What should I do to fix all this?
Boot disk!
First you will have to get the one from which you installed the system. However, a regular image of normal Windows, recorded regular means to or flash drive. If we talk about older systems, then you should repair Bootmgr is missing XP using disks, since older BIOS versions cannot always adequately load the recovery environment from another medium.
Insert the media into the drive (or USB port), and then restart the computer. In the BIOS you set it to boot from the media you require. Let’s immediately make a reservation that it is the flash drive that is best used for repairing Bootmgr is missing. Windows 7 perfectly supports booting from such drives right out of the box, and what is important to the user is high loading speed and a minimum of errors, which are not so rare when starting a recovery environment from an optical disk.
After this, wait until the system finishes loading necessary files. The installation wizard will appear.
Setting up the "Wizard"
Select the desired language and other parameters, click on the “Next” button. Another window will appear with a large “Install” button. There is no need to click it, since you need to click on the small “System Restore” item located in the lower left corner. In “System recovery options” and “Selecting an archive image”, click “No” and “Cancel”, respectively.
The “Recovery Options” window will open again, in which you need to left-click on the “Command Prompt” option.
The most important thing
Now we will use the diskpart utility, with which you can easily change the active disk partition.
By the way, what is an active section? Simply put, this is exactly the area of the disk from which the operating system is directly loaded. Keep in mind that there may be more than a dozen such areas on the hard drive, each of which is designed to load its own operating system. But the OS will start exactly from the partition that is on at the moment is active. However, all this is poetry.
Note that at the moment there are a huge number of different utilities designed for editing partitions. With their help, you can designate even one of a dozen areas located on one logical drive as active! However, it is better not to engage in such experiments if you have little experience, since the risk of losing all the data on the disk is very high.
In this case, the user will inevitably see Bootmgr is missing. You’ll find out what to do now, but it’s better not to risk it.
How can I “activate” a section?
Let's digress a little again to once again talk about the importance of active sections. Many beginners, starting to experiment with the system, often strive to “optimize” it as much as possible, which most often results in a desire to reduce the space it takes up on the hard drive. It is these “unnecessary” sections that most often fall under the knife.
If you select “Disk Management” in the “Administration” panel, you can clearly see all the disks that are in the system, as well as all their partitions. The active area in "Seven" must be at least 100 MB in size, and in Windows 8 - at least 350 MB.
Its importance is indicated by the fact that you cannot see it from the usual Explorer. As you can easily understand, all this was done for the security of the system: if you give inexperienced users access to it, you will probably have to reinstall the OS.
We're working!
To recover data on a disk, you will need to follow the commands below consistently and very carefully. You need to do this slowly, since otherwise you will probably make a mistake when entering it, and the next time you boot the system you will again see Bootmgr is missing, press any key.
- Diskpart. This special program, launched in command line mode, is designed to manage hard drive partitions. Once upon a time, the FDisc utility performed the same function.
- List disk. This command will display on the monitor a list of all hard drives connected to the system, simultaneously assigning numbers to them all. Attention! The following operations should be done as carefully as possible, without making any mistakes!
- Select Disk x. Instead of “X”, put the number of the hard drive from which the operating system you require should boot.
- List partition. This command allows you to once again make sure that you have selected the correct area, since when you use it, all partitions that are on the hard drive you selected will be displayed again.
- Select Partition x. As you can understand, this time the “X” is replaced by the number of the partition that should be made active in order to boot the OS from it.
- Active. This option is precisely responsible for activation.
This is how Bootmgr is missing is “treated”. Windows 7 is a reliable system, so if all the above steps are performed correctly, it will work for a very long time.
During operating room startup Windows systems 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 damaged hard drive sectors, as well as non-working SSD cells. 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 ineptly uses 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” - creates a special boot record on the current 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.
It will pass full scan operation of the operating system of a personal computer. 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 recording Bootmgr is missing. what to do in Windows 10
If you have tried all of the above steps and nothing really helps you, you can take extreme measures. Let's try to reserve the old BCD folder, which is responsible for starting your personal computer during operation and create a new Bootmgr when installing from a flash drive directly to your personal computer(PC). Please note that further actions with this command must be carried out according to 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 drives, and begin to forcefully reboot the OS.
- Checking the basic parameters BIOS settings, which indicate the priority of booting the computer. It is possible that the disk, which in this case is not the system one, starts loading first by accident. Also check through the BIOS or a 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 did a full format, 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.
