I typed the following commands:

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd, and any of these commands does not help. I restarted my PC and showed an another error on blue screen:

Recovery

Your PC needs to be repaired

The operating system could not load because the critical system driver is missing or contains errors.

File: \WINDOWS\System32\Drivers\kbdhid.sys

Code: 0xc000021a

You will be need to use recovery tools. If you do not have these tools, contact your system administrator or PC manufactuer.

I do not have to reinstall Windows, because I have saved a lot of critical files and my files on that PC.
