Fixing a TPM BitLocker Key

Tue, 04 Mar 2025 00:48:44 -0800

System firmware updates amongst other boot changes can cause a TPM based Bitlocker key to become invalid.

When you attempt to boot into windows you’ll get a blue screen asking to unlock the drive.

Hopefully you have a copy of your bitlocker recovery key. Sometimes you can find this on your microsoft account.

Enter the key into the blue window and boot into windows. Now if you don’t fix the issue, you’ll continue to have that blue screen every boot.
