Question

A technician is troubleshooting a Windows 10 laptop infected with a virus that has damaged the master boot record. The technician has booted the laptop using the installation media and is attempting to repair the laptop from the command line interface. Which command can the technician use to repair the corrupt master boot record?

Answer 1

To repair a corrupt master boot record (MBR) on a Windows 10 laptop, the technician should use the bootrec /fixmbr command from the Windows Recovery Environment.

Step-by-step explanation:

The technician can use the bootrec /fixmbr command to repair a corrupt master boot record (MBR) on a Windows 10 laptop.

This command writes a new master boot record to the system partition. It is used when the existing MBR is corrupted or damaged due to a virus or other issues.

This is one of several tools available for system recovery that can be accessed through the Windows Recovery Environment (WinRE).

In addition to bootrec /fixmbr, other bootrec options include /fixboot, /scanos, and /rebuildbcd, which can be used to fix other boot-related issues.
