Fix the “Cannot install Windows, BitLocker Drive Encryption is enabled” error by disabling BitLocker, unlocking with a recovery key, or deleting the partition.

The Windows 10 boot and shared data partitions somehow got encrypted with Bitlocker (and thus are inaccessible from the Win 8.1 install) after a repair shop swapped the motherboard.

Affecting Windows 10, Windows 11, and Windows Server, the bug prevents your PC from booting into Windows, instead resulting in a blue screen that asks for your BitLocker recovery key.
