Instructions for restoring the Windows 7 bootloader

Often, after an inexperienced or simply overconfident user plays with the computer settings, he starts to give various errors - up to. In most cases, they are easy to fix by simply asking Google the right questions.

But what to do if even the system does not want to boot?

Description of the problem

A black screen and ugly white labels make inexperienced users feel discouraged, making them want to immediately format the C:\ drive and install a new system. It's not always the smartest thing to do. Let's take a look at one of the most common errors that prevent the operating system from booting: corrupted Windows bootloader. 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 taken directly. English-speaking people can easily translate "The boot manager is missing, press Ctrl + Alt + Delete to reboot."

Let's see what these words mean. For convenience, we will break this message into two parts:

The download manager is missing. This does not mean at all that you have deleted all information from the disk or that the hard drive itself is missing. The system means that it cannot read the information about where to boot the system from. It can't, so it doesn't, - that's the kind of computer logic.
Press Ctrl+Alt+Delete to reboot. A classic of the genre - by pressing these keys, you simply restart the computer, and the error remains. This can be repeated ad infinitum.

From this we conclude: everything is not so bad, because the problem can be corrected programmatically. To do this, we need to perform a special procedure - restoring the windows 7 bootloader. There are two ways to do this.

Restoring the bootloader through system restore

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

Let's consider them separately:

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

You can run this program by writing the command "Bootrec.exe" in the command line. After that, the utility will display a list of keys with which it works, and you select the one you need and write: Bootrec.exe "the desired key". Just do not forget that the keys are written with a space.

BCDBooT system utility. This program is used to create or restore a boot record. That is, it must be used when it is damaged or completely absent.

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

Restoring the bootloader without a boot disk

This method is almost identical to the first one, 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 in this way, you need to do the following:

After turning on the computer, before loading the operating system, press the F8 key.
If you did everything correctly, a window of additional download options will open.
