Hold down an arrow key as the machine boots. Grub will stop the
countdown.

Generically, you can change the root password this way:
Use the arrow key method to stop GRUB from booting immediately.
Choose to edit the boot command.
Add the string
init=/bin/sh
to the command line, then boot.
It should make you root, with no network and no services
started.
mount -o remount,rw /
will make the disk read/write instead of read-only. Now run the
passwd command to reset root's password. You will not need to
supply the old one.
Finally:
sync
and then reboot or power-cycle.
