You can even do it without the CD.

At the GRUB command line, add this to the kernel= line :


This gets you to a bash prompt without asking for a password. From 
there, you mount the root partition in r/w mode :

# mount -o remount,rw /

Now you can reset your password :

# passwd

Since the system wasn't booted in a very orthodox way, we have to shut 
it down a bit differently.

# mount -o remount,ro /

Now simply press the power button to switch the machine off.
