Hello again Ryan,
I wanted to know if you have resolved the issue or not. To summarize the resolution for your BitLocker lockout, your primary validation method is to match the first 8 characters of the Key ID displayed on your screen with the identifiers listed at account.microsoft.com/devices/recoverykey. If the specific BitLocker prompt is not visible due to the Linux installation, you should filter the keys on the portal by the Key Upload Date that aligns with your original PC setup. Alternatively, as you only have five keys listed, you can safely attempt to input them sequentially; entering an invalid BitLocker recovery key will not trigger a security lockout or damage the drive, it will simply reject the attempt until the correct one is found.
If the issue has been successfully resolved, please consider accepting the answer as it helps other people sharing the same question benefit too. Thank you!
VP
