Need to remove grub password

logaritse

Hello everyone, i need help how to remove ubuntu 16 grub password ?

already boot with live cd and try to edit /etc/grub.d/40_custom file and replace with new generated password doesn't work

is there any way to disable grub password.

Thank you

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
