FVE_E_NO_PROTECTORS_TO_TEST

The pre-encryption test needs an unlock path

BitLocker can perform a restart-based hardware test before committing an operating-system volume to encryption. The test verifies that the configured TPM, PIN, startup-key media, and boot environment can release the key during early startup. FVE_E_NO_PROTECTORS_TO_TEST means there is no protector configuration for that test to exercise.

This status should not be bypassed by assuming that encryption itself will create a usable recovery path. A volume can be prepared or partially provisioned while protection remains incomplete. The meaningful distinction is between encryption state and protection state: encrypted sectors are not enough if no secure protector is enforced.

Diagnostic steps

Use manage-bde -status and -protectors -get to capture conversion, protection, and protector state separately.
Add the policy-approved protector and make sure recovery information is backed up before rerunning the hardware test.
For USB startup keys, verify that firmware can enumerate the device during preboot, not only after Windows loads.
Do not use -SkipHardwareTest as a generic fix when the deployment requires preboot validation.
