Dell laptop can not restore previous backup due to bitlocker volume identified

Thread needs solution

I have a new dell laptop approx 4 weeks old and rebuilt with all data and apps from previous laptop (500 gig) .. I created an Acronis full  backup to a crucial SDS portable drive 3 days ago. 

Since then a system problem has resulted in Dell support performing a factory reset. 

In trying to restore the backup created 3 days ago it fails with message 

“Unable to continue the operation that needs a reboot because a volume encrypted by bitlocker has been detected. Please use Acronis bootable media.”

questions - is the bit locked drive on the Dell laptop or the SDS drive but more importantly how do I restore my backup ?

help appreciated.

Stuart, welcome to these public User Forums.

Please open an Administrator level Command prompt window then run the command:

manage-bde -status

then check the report for each drive found by this command.

Example output from my laptop.

If you see any volumes where the BitLocker status is either encrypted or pending activation etc, then you will need to run a further command:

manage-bde c: -off

replacing c: with the drive letter for the volume with BitLocker.
