Problems with the computer always spoil the mood of users. But one thing is the browser crash due to plugin malfunctions, and the other thing is Bootmgr is missing. What to do in this case is not always presented even by experienced users. Today we will tell you what kind of error it is, why it appears, and how to fix it.
What it is?
In general, the appearance of such a message at boot is a very serious and bad signal, indicating problems 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 conducted the experiments with partitions. Sometimes a similar situation occurs after an emergency shutdown due to a power outage.
Important! In the latter case, you really can start to seriously worry: 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? Alas, in this case, only replacing the hard drive will help. However, we 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 hard drives used on such computers, and in some system features inherited from the "ancestors".
If a person is inexperienced, then often he assumes that the hard drive crashes, 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 quite overcome Bootmgr is missing. What to do to fix all this?
Boot disk!
First you have to get the boot disk from which you installed the system. However, with the same success, the usual image of normal Windows, recorded by regular means on an optical disk or flash drive, will do. If we talk about old systems, then repairing Bootmgr is missing XP should be done with the help of disks, since older versions of the BIOS can not always adequately boot the recovery environment from another medium.
Insert the media into the drive (or into the USB port), and then restart the computer. In the BIOS, set the boot from the media you need. Immediately make a reservation that a flash drive is best used to repair Bootmgr is missing. Windows 7 perfectly supports booting from such drives directly out of the box, and for the user the high download speed and the minimum of errors, which are not so rare when starting the recovery environment from an optical disk, are important.
After that, wait until the system finishes downloading the necessary files. The installation wizard
dialog box appears.
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. It is not necessary to click it, since you need to click on the small item "System Restore", located in the lower left corner. In the "System Restore Options" and "Selecting an Archive Image" click "No" and "Cancel", respectively.
The “Recovery Options” window opens again, in which you need to left-click on the “Command Prompt” option.
The most important
And now we will use the diskpart utility, with which you can easily change the active disk partition.
By the way, what is an active partition? Simply put, this is exactly the area of ​​the disk from which the operating system is directly loaded. Keep in mind that the hard drive can have more than a dozen of these areas, each of which is designed to load its operating system. But the OS will start from the very section that is currently active. However, all this is lyrics.
Note that at the moment there are a huge number of different utilities for editing partitions. With their help, you can make active even one of the ten areas located on the same logical drive! 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. What to do, you will now find out, but it’s better not to risk it.
How can I “activate” a section?
Again, a little distraction to once again talk about the importance of active sections. Many beginners, starting to experiment with the system, often seek to “optimize” it as much as possible, which most often translates into a desire to reduce the space occupied by it on the hard drive. “Under the knife” most often fall precisely these “unnecessary” sections.
If you select the "Disk Management" item in the "Administration" panel, then you can clearly see all the disks that are in the system, as well as all their partitions. The active area in the "Seven" should be at least 100 MB in size, and in Windows 8 - at least 350 MB.
Its importance is indicated by the fact that from the usual “Explorer” you will not see it at all. It is easy to understand that all this is done for system security: if you give inexperienced users access to it, you will probably have to reinstall the OS.
We are working!
To recover data on a disk, you will need to execute the following commands sequentially and extremely carefully. You need to do this in a hurry, because otherwise you will probably be mistaken at input, and at the next boot of the system you will again see Bootmgr is missing, press any key.
- Diskpart. This is a special program, launched in command line mode, designed to manage hard disk partitions. Once 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 them all numbers. 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 need should be loaded.
- List partition. This command allows you to once again make sure that you have selected the correct area, since when using it, all partitions that are on the selected hard disk will be displayed on the screen again.
- Select Partition x. As you can understand, this time instead of “X” is the number of the partition that should be made active for loading the OS from it.
- Active This option is just for activation and is responsible.
This is how Bootmgr is missing is "treated". Windows 7 is a reliable system, so that if all the above actions are performed correctly, it will work for a very long time.
