Many distros will still ask for the root password when you boot in single- user mode. If this happens to you, try the following (this won't ask for any passwords): - Boot with "init=/bin/sh" on the command line (where you would enter "single"). - You'll get a prompt, but the root filesystem is still read-only. Make it read-write with the following incantation: mount -n -o remount,rw /dev/XXXX / (where /dev/XXXX is replaced with your root device (often /dev/hda1)). - run "passwd root" and enter a new password. - "umount /" and reboot (with the reboot command or just power-cycle, the disk will be fine since / is "unmounted" (really remounted read-only)).
