    Why not just remove/disable the password instead of trying to set a new one from your live-cd environment?

    Because I try not to assume.. When using the live-cd environment, /etc/grub.d/ is the wrong path.. That will be the live-cd grub files.

    The file may be /etc/grub.d/40_custom or 00_header

    P.S.
    grep password /etc/grub.d/*

    remove the file containing the superusers.
    sudo -H gedit /etc/grub.d40_custom/
    dont forget to update grub
