    You need to mount the filesystem as read-write (rw). Do step 4 and type "mount -rw -o remount". You can also go into the recovery menu first, select "fsck" which will mount your filesystem as rw (and it will also check the disk for errors too) and after that you can use the root shell.

    Inside a terminal, type sudo nano /etc/default/grub. After finding #GRUB_DISABLE_RECOVERY="true", uncomment that line. Then, exit the nano text editor (make sure to save changes).
