FVE_E_OS_NOT_PROTECTED

FVE_E_OS_NOT_PROTECTED generally indicates a prerequisite problem: the operating-system drive is not protected, so a dependent data-drive feature such as automatic unlock cannot be configured safely.

What to check for FVE_E_OS_NOT_PROTECTED

Verify protection status for the Windows OS volume before managing dependent data-volume settings.
Confirm that the OS volume has suitable recovery material and a supported protector configuration.
Do not enable automatic unlock as a substitute for OS-volume protection.
