Step 1
You can boot the system from the command line regardless of whether your operating system is running or the computer is constantly rebooting. The main thing is that it starts loading. Even if the OS crashes, if the initial boot starts, you can boot from the command line.

To find out the commands that you can use to try to restore normal operation of the operating system, enter the Help command at the prompt. A list of commands that you can enter will appear on the left side of the window, and a description of each of the commands on the right side.
Step 4

If you have a system drive called a different letter, then enter it.
Step 5
Also, using the command line, you can start the system restore process. To do this, enter the Rstrui.exe command. A console will appear, with which you can restore Windows to work. Also, for the recovery process, you may need a disc with the distribution of your operating system.
