Lenovo Helix Laptop: Bitlocker appears to be preventing boot

We have a Lenovo Helix laptop that will not boot and getsand unmountable drive error.

I was able to finally get to the Windows recovery screen and have tried several options that are not working. But each option required entering (the correct) bitlocker password.

The drive is C but bitlocker created an X drive.
manage-bde -status
Volume c:[]
[Data Volume]

Size:					Unknown
Bitlocker Version:		2.0
Conversion Status:		Used Space Only Encrypted
% Encrypted:			100%
Method:					AES 128
Protection Status:		On
Lock Status:			Unlocked
Identification Field:	Unknown
Auto Unlock:			Disabled
Key Protectors:			Numerical Password TPM

Open in new window


When I am tried the code below to remove bitlocker
manage-bde -off c:

Open in new window

I received the error
ERROR: An error occurred (code 0x80070015)
The device is not ready.

The Bitlocker metadata for the encrypted drive is not valid.  You can attempt to repair the drive to restore access.

As I wrote, feel free to try repair-bde on the unlocked drive.
I had already tried repair-bde and that generated an error as well.  It's looking like re-imaging is the only option.
It definitely does.
manage-bde -off c: or repair-bde would have been the best answer, however, in my case the system was bad enough I had to re-image.

Thank you McKknife
