I have followed the instructions for turning on BitLocker with no TPM. It looks like the startup key is being written properly to my USB flash drive, but after restarting in order to run BitLoocker encyption, I'm getting this notice ... BitLocker could not be enabled. The BitLocker startup key or recovery password cannot be found on the USB device. Verify that you have the correct USB device, that the USB device is plugged into the computer on an active USB port, restart the computer, and then try again. If the problem persists, contact the computer manufacturer for BIOS upgrade instructions. C: was not encrypted. See attachment.
The USB flash drive is plugged in. It has what appears to be a startup key (.BEK file) in the root folder. It also has a text file in the root folder which contains the recovery key.
Any ideas?
