Third: With BIOS, quickly press and hold the Shift key, which will bring up the GNU GRUB menu. (If you see the Ubuntu logo, you've missed the point where you can enter the GRUB menu.) With UEFI press (perhaps several times) the Escape key to get grub menu.

chmod 440 /etc/sudoers
chown root:root /etc/sudoerseighth: press Control-D to close prompt, then, select resume option to continue restarting.
