After decrypt, preboot authentication does not accept password
« on: September 22, 2011, 06:28:16 am »
I had my Windows Vista laptop encrypted for the last year. I didn't need the encryption any more, so I just decrypted it. (Decrypted both volumes: main volume and recovery volume). I rebooted, and the DiskCryptor preboot authentication prompt still shows up, and it does not accept my password any more. What can I do about this?

You can create a WinPE CD with DiskCryptor and use that to remove the bootloader. Or you can try to enter a false (or no password) at the prompt.

Awesome. It was as easy as hitting return at the password prompt. That got me right to the login screen. (Typing the password just failed over and over.) And to think that I tried to make a WinPE disk. What a horrible thing to have to do.

By the way, I don't know how one can "create a WinPE CD with Diskcryptor" because there doesn't seem to be an option for that. Instead I tried following the directions here: http://www.computerhope.com/forum/index.php?topic=87312.0

Thank you!

"Hitting return" method didn't work for me, but I fixed the MBR easily with Windows installation media. Just type "bootrec /fixmbr" in the command prompt. Done.
