6 Solutions – The Drive Where Windows Is Installed Is Locked

Method 1: Rebuild MBR With MiniTool Partition Wizard

MBR (master boot record) is a special type of boot sector at the very beginning of partitioned computer mass storage devices. It contains a small amount of executable code called the master boot code, the disk signature, and the partition table for the disk.

And the master boot code scans the partition table for the active partition, finds the starting sector of the active partition, loads a copy of the boot sector from the active partition into memory, and transfers control to the executable code in the boot sector.

Once the master boot code is damaged or corrupted, you are likely to receive the “The drive where Windows is installed is locked” error message when booting or refreshing your computer. So, you can try rebuilding MBR to see whether the Windows-locked hard drive error can be fixed.

Now, you might be wondering: How to rebuild MBR effectively to unlock drive Windows 11/10/8/8.1?

Here, MiniTool Partition Wizard, a professional partition manager is recommended. This tool offers you the Bootable Media feature that can help you start the unbootable computer and rebuild MBR.

Tips:

Tip: The free edition of MiniTool Partition Wizard doesn’t provide Bootable Media Builder since this feature is only included in any paid editions. Here, you can get MiniTool Partition Wizard Pro Edition to rebuild MBR to unlock a hard drive.
