Fix INACCESSIBLE_BOOT_DEVICE After Cloning the Windows System Feb 25th 2022 Words: 104

Problem

I bought a larger NVMe and successfully cloned my Windows to the new SSD. However, when the Windows boots up, a BSoD pops up with error code INACCESSIBLE_BOOT_DEVICE.

Solution

Boot into Windows PE and launch the registry editor.

Click File > Load Hive

Open the registry file of the Windows installation to be fixed at \WINDOWS\SYSTEM32\CONFIG\SYSTEM. The name off loaded hive can be anything.

Delete the key under HKLM\<loaded_hive>\HardwareConfig

Unload the hive and save changes.

Boot the Windows and cross your fingers.
