Surface Pro i5 with latest MS Windows 10 Pro updates installed. Only Windows 10 installed.
I was copying some files to external USB for backup and system rebooted to BSOD and Stop Error “Registry-Error”.
System then goes into reboot cycle until a forced shutdown.
Unable to enter Safe Mode. System just boots back to BSOD error screen.
Tried a repair with a system recovery disk/tool downloaded from MS. Asks for BitLocker key then fails with unspecified error. Disk is for this specific model of Surface Pro.
Tried installing new Windows 10. Install asks for BitLocker key and then fails.
BitLocker key is accepted as correct in both cases.
Using Command Prompt I can see drive and partitions. Attempt to turn off BitLocker fails and reports drive write protected.
CHKDSK reports write protected but reports no errors.
TPM is enabled.
Google suggestions for turning off BitLocker from Command prompt fail.
