I have a Vista machine with a password at bootup but do not have the password. I am trying to use Knoppix in an attempt to access files on the Vista machine.

I have downloaded Knoppix using an XP machine. I d/l V5.1.1 2007-01-04-en.iso and burned on to a cd.

After changing the boot setup, the computer shows only a black screen. It does not boot up.

What have I missed?
