Help with user permissions?-(So i can change grub)

mitchell7man · 03-15-2007, 11:00 PM

Hello, I have ubuntu edgy, and I am trying to change grub, but when i try to save files in the grub folder it says, "cannot save b/c you do not have permissions" (not owner), I do this, in the only account i have, so what do I do to become the "owner", and be able to edit grub etc.?

You need root permission. Enter the command:

su -

(that's su followed by space hyphen). It will prompt for your root password. When you are done, exit.

Hi, thanks for the help, but I do just as you say, i enter the only password i know of, the one on my user that i created when I installed the system, the only user I have, and it Says "authentication failure", dont know what's up, anyone know what to do ?

If you don't have a root password, try:

sudo su -

or

sudo bash

If the prompt changes to a '#', then you now have root access.

Hello, that gives me root access, but i am editing the files directly in the "filesystem" and it still does not allow me to save the changes I make, thanks, still searching for how to get access, MJ
