While in there I accidenty deleted admin from the group now sudo command doesnt
accespt password and home has nothing either, i have just read on the net

"During the grub screen on startup press escape to get into the grub menu. From
there select 'recovery mode' and it will boot you into a CLI as root. From there
you should then be able to recreate your groups and add yourself back onto the
sudoers list."
