Moved from Consumer Help section to 'Business / Data Protection / Encryption: ePO Managed' for attention.
please upgrade to the current version - it has many fixes for BIOS issues.
Some of the Insyde BIOS try to read the OS Boot Record from the disk. Since the OS Boot Record is encrypted the boot process may fail. I suggest that you try the solution provided in 5.2.10, for more details please see KB72626.
