    Hi @Brink Any specific reason why not to use the destination\recover.img in the commands?
    I've never used it to say. I've always just used a spare drive.

    Thanks Shawn for a great post.

    I have a Dell XPS 9560 with Bitlocker encrypted system drive. Recently Windows 10 displayed a notification (coloured red instead of the usual blue) indicating some kind of storage related error (I didn't note the exact text unfortunately). Shortly after when trying to launch MS Word I received an error "The operating system is not presently configured to run this application". So I closed everything and rebooted.

    On reboot, after entering the Bitlocker PIN as usual, the PIN is accepted but then the system hangs showing a black screen containing Dell logo and 'spinning dots' infinitely. I can enter recovery mode via F12 boot menu so as to unlock using the recovery key, which is accepted, but it still hangs unlocking. Same occurs after making a bootable USB drive, booting to the custom install screen and opening a command prompt and then performing a manage-bde -unlock C: -RecoveryPassword <my recovery key>.

    So I've reached the point of assuming there's a problem with the Bitlocker metadata, and found your article. Again booting from the USB and opening the command prompt I attempted to repair as per your post.

    My broken Bitlocker drive is C: and my external 1TB USB to recover to is H:. I had trouble with repair-bde complaining that H: was in use even after using -Force, so I formatted it and ran repair-bde again. It seemed to do the trick, but my problem is the repair-bde command appears to have hung after indicating it's finished the decryption, and telling me of the action required to run the chkdsk. Note in the screenshot at Screenshot.jpg - Google Drive, the cursor is flashing, and the window hasn't returned to the command prompt. It took maybe a couple of hours to recover the data (C: was a 500GB SSD), but the command has still not completed after about another 5 hours. Additionally there is a repeating pattern of disk activity indicated by the LED on the external USB. Should I wait? Should I hit <cntrl-C> and then run the chkdsk?

    Thanks in advance.

    Cheers,

    David.

    Hello David, and welcome to Ten Forums.

    I would go ahead and run chkdsk to be safe.

    Thanks Shawn. As it turned out the session hung because the external drive suffered a failure during the recovery. I had to hard reboot the machine. When connecting the USB drive to which I recovered to any other PC it would just hang, with the drive showing the same repeating pattern on it's LED. I ended up destroying the external drive & binning it, and just rebuilt my XPS from scratch, restoring data from backups. I have an system image backup as well now. :)

    Cheers,

    I was afraid it was going to be hard drive failure as the cause.
