You can even do it without the CD.
At the GRUB command line, add this to the kernel= line :
init=/bin/bash
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.
