Cannot boot "full" encrypted BT5

I followed the guide on: http://www.infosecramblings.com/back...sk-encryption/
to install BT5 on an encrypted / on my system (not on a usb-drive) consisting of another linux installation.

However when booting BT5 I never get the chance to enter the password. If I boot with the dvd and run cryptsetup I'm able to unlock and mount the encrypted partition but not when booting my installed BT5.

I guess I have done something wrong when configuring this but can't find the error. Can anyone see what's wrong?

Edit: Well... all I needed to do was to press F8 and log in. It was in the guide. RTFM on me.
