I have activated Bitlocker on two identical W8.1 pro machines, and on the first (C1) I have the option to use a password when logging into the computer, but the other (C2) only ask for the recovery key from USB stick. Both computers have no TPM, so Bitlocker is enabled without TPM, but this should give the possibility to start the computers using a password on 8.1 pro.

Can I somehow add a password to C2, or is my only option to remove the Bitlocker encryption and try again?
