Windows 10: Fix boot problem without Bitlocker recovery key?

I have a PC that I've been asked to fix. It's blue screening on startup with stop code 0xc00021a. The user tried restoring to two restore points and said "it didn't work" - no details. Then they said they were prompted on boot for a Bitlocker recovery password, which seems to be missing. That's the state I found the laptop in - for some reason secure boot had been turned off. I turned it back on, so it's no longer prompting for a Bitlocker recovery key first thing on powering up, but I am not able to do any of the recovery options without one.My question is, are there any options short of full

:)

Bitlocker recovery key

Hello,

I'm the IT user-support person in a company and I have this issue with a corporate laptop (belong to a domain & Active Directory):

I received from a user his laptop "dead" (no power-on, nothing to start-it). Accordingly to company security policies I deliver the laptop in service with another blank disk (the same SSD type) because the original one contained data.

After receiving the fixed laptop from service, I changed back the disks by putting the original one at it place.

Now, it occur the issue: at first step of booting it request the Bitlocker recovery key because the disk was bitlocker encrypted before.

The bad-luck is that I don't have this Bitlocker recovery key nowhere: on the printed paper, USB memory stick and not even on the Active Directory.

Is strange, because ussually, the other workstations (laptops with bitlocker activated) have this information on Active Directory.

Maybe because of a possible cause: the laptop owner use to work at home with the laptop and the Active Directory didn't synchronized the information related to Bitlocker recovery key (like for other laptop used in LAN).

I have the "Recovery key ID" on the blue screen for the laptop but is useless because I cannot find the "Bitlocker recovery key" on Active Directory using it.

What do you suggest to do in this case?

Many thanks for any advice and answer.

Mircea Dumitrescu.
