Well, no wonder: the command you're using is wrong. Try this instead:

su -c 'gedit /etc/default/grub'

And enter the root password when prompted. (As always, the password won't echo, not even stars.) Using the -c tells bash to give you root access only for the one command, rather like sudo.

sudo works! Thanks for that! But now when i save after editing the grub file, it gets saved but terminal says that the action has failed because no such directory exists. And the changes are not executed! Any solution?
