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.
