Default Behavior

BitLocker Drive Encryption Filter Driver is a kernel device driver. In Windows 10 it is starting by the operating system Boot Loader as a part of the driver stack for the boot volume. If BitLocker Drive Encryption Filter Driver fails to load or initialize, Windows 10 attempts to record the error details into Event Log and restart the PC, using the Last Known Good configuration. If the Last Known Good configuration cannot be applied or working improperly, Windows 10 startup process halts with a Stop error. If you disable or delete the fvevol service, Windows 10 won't start.
