Did you make a bitlocker recovery usb stick ? Use that.

 

If the laptop was set up by a company, then you would need to contact their IT. If it is your own personal one, then you need to contact Microsoft as they will have the key stored under your Microsoft login.

If you have any other software like Sophos that uses BitLocker for encryption, then you will need to contact them.

how to use that

 

Then I would say that you are not using the correct password, but I may be wrong.

 

The bit locker recovery password is about 8-10 sets of 6 numbers that typically resides in Active Directory. If you have a personal computer, you probably would needed to store the recovery key (2 different things) on an USB drive.

You need to unlock the drive first before trying to access the drive. The problem I see is that if the hardware thinks it's still in the wrong computer, you will need to keep entering the bitlocker key.

To confirm, is this a computer you purchased, or a company provided computer?

 

Bitlocker info can be printed or saved as a PDF.

Maybe the software you used to get into Windows caused a problem.

If you have the Bitlocker recovery USB memory stick, insert the stick and reboot the PC.
