Corrupted MBR on External Drive in Windows 7/10 - How-to Fix?
Geeks - If the Master Boot Record (MBR) on your external drive is corrupted, you can try to fix it using the following steps:
Connect the external drive to your computer.
Open the Start menu and type "cmd" (without quotes) in the search field.
In the search results, right-click on "cmd" and select "Run as administrator" to open the command prompt with admin privileges.
At the command prompt, type the following command and press Enter:
Copy code
bootrec /fixmbr
This command will attempt to repair the MBR on your external drive.
If the above step doesn't work, you can try the following command:
Copy code
bootrec /fixboot
This command will attempt to repair the boot sector on your external drive.
If you still can't boot from the external drive, you may need to restore the MBR and boot sector from a backup. To do this, you will need to use a tool like SystemRescueCD, which is a free, open-source live CD that you can use to repair a damaged MBR and boot sector.
I hope this helps. Let me know if you have any other questions.
