Fix MBR From Command Prompt in Windows 10, 8, 7

Geeks - To fix the Master Boot Record (MBR) in Windows 10, 8, or 7, you can use the bootrec.exe tool. This tool is part of the Windows Recovery Environment (Windows RE) and can be used to troubleshoot and repair boot errors.

To use bootrec.exe, follow these steps:

Insert your Windows installation media (e.g. a USB drive or DVD) into your computer and restart your computer.

Press a key (e.g. F12) to enter the boot menu and select the option to boot from the installation media.

On the "Windows Setup" screen, select your language, time and currency format, and keyboard or input method, and then click "Next".

Click "Repair your computer" in the bottom-left corner of the screen.

On the "Choose an option" screen, click "Troubleshoot".

Click "Advanced options".

Click "Command Prompt".

In the Command Prompt window, type the following commands and press Enter after each one:

Copy code

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

These commands will fix the MBR, rewrite the boot sector, scan for installed Windows installations, and rebuild the boot configuration data (BCD) respectively.

Once the commands have completed, type exit and press Enter to close the Command Prompt window.

Click "Continue" on the "Choose an option" screen to restart your computer. Your computer should now boot normally.

If you continue to have problems with the MBR, you may need to use additional troubleshooting steps to resolve the issue. It may also be helpful to check your computer's documentation or contact the manufacturer
