Hi,
Thank you for posting in Microsoft Q&A forum.
One possible solution is to check if the hardware or software prerequisites for BitLocker are in place. Examining the BitLocker-API log can help identify which prerequisite is not satisfied. The most common issues are TPM not being present, WinRE not being enabled, and UEFI BIOS not being enabled for TPM 2.0 devices. Policy misconfiguration can also cause encryption failures.
Another possible solution is to override the default setting on the Specify the BitLocker recovery details page in the Windows Deployment Wizard. The Windows Deployment Wizard summary page displays a warning to inform the user which drive letter was selected to store BitLocker recovery information. In addition, the BDD.log and ZTIBDE.log files record the removable media devices detected and which device was selected to store the BitLocker recovery information.
