Accidentally cleared TPM on BitLocked computer

Question

One of my technicians was supposed to image a computer that has BitLocker enabled. He didn't know the access pin and instead inserted a Dell boot disk to do a soft-restore (keeping all of the clients files and resting windows). There was a warning notifying him that he was clearing the TPM. He pushed "OK" and now the computer boots to a black screen. I have the recovery key and can access the BIOS but that is about it.

I have been googling for a few hours now and I cant find anything that will help. Thoughts?

In theory you should be able to add the disk to another machine, use the recovery key to unlock the disk, then remove bitlocker. I want to emphasize the "in theory" part as I've never done it, and t is simply theory (IMHO) until it works in the real world.

That was going to be my next step. Thanks for the reassurance. I will have to try this in the morning. – Mike Hendrix Nov 17 '16 at 02:21
In theory. Based on the description, I rather suspect that the contents of the drive are permanently lost. – Michael Hampton Nov 17 '16 at 02:24
Yeah I don't want to get anyones hope up too much, but it's certainly worth the shot. – Jim B Nov 17 '16 at 14:25
