    To fix the BitLocker issue:

    1. Create EFI Partition: Ensure Disk 4 has a 100+ MB FAT32 EFI partition.
    2. Repair Boot Files: Run:bashbcdboot C:\Windows /s X: /f UEFIReplace X: with the EFI partition letter.

    bcdboot C:\Windows /s X: /f UEFI

    3. Set Boot Priority: In BIOS, set Disk 4 as the primary boot drive.
    4. Test Boot: Disconnect Disk 5 temporarily to confirm booting solely from Disk 4.
    5. Enable BitLocker: Retry after verifying the above steps.
