They’ve changed it a little, still, press “a” at grub to get the append kernel parameters line, still add ” single” to the end of it.
BUT instead of using passwd (this really confused us) which just returns to the next line without asking for a password use:
passwd -d root
This blanks root’s password so when you reboot it doesn’t ask for a password! Freaky stuff!
