I have been trying to achieve something similar on my system. Password protection in grub2 appears to be quite different from that in grub-legacy.
In grub2, authentication is activated by the lines (from the grub info manual, the section on security): set superusers="root" password_pbkdf2 root grub.pbkdf2.sha512.10000.biglongstring in the /boot/grub/grub.cfg file The command grub-mkpasswd-pbkdf2 can be used to generate the password. On debian systems, it is better to put those two lines in /etc/grub.d/40_custom to make sure that your changes remain after an `update-grub' command. But, be advised that once you do this, all the menu entries in grub will be inaccessible until the password is supplied. It would be nice to have a way of requiring a password only if it required to boot a non-default entry. On Wed, Mar 16, 2016 at 11:12 PM, Himanshu Shekhar <irm2015...@iiita.ac.in> wrote: > Ok!
