If FDE preboot fails to load
This happens when Bypass Preboot policy is disabled. Use the FDERepairCD.iso to access the Recovery Console.
To access Recovery Console using Repair CD:

- Click Recovery Console.
- In the left pane, click Decrypt Disk.
- Click Decrypt found on the bottom right. Wait until the decryption process completes.
After the decryption process completes, use the Restore Boot option in the Recovery Console to restore the machine to a previous state where FDE is not yet installed.
