Edit corrupted grub file on my system from Ubuntu 9.04 Live CD

[wklang]

My face is red.

I edited my menu.lst file in the /boot/grub directory and made a serious typo. I get a kernel panic on trying to boot. (I saved a backup of the original (working) file before I edited the menu.lst file.)

I booted from the Ubuntu 9.04 Live CD and then navigated to the corrupted file on my machine. I can see it, open it in an editor, but cannot save the fixed file becuause I don't have root privileges (on the Live CD, I presume).

Any ideas on how I can gain editing access to my grub menu.lst file?

Thanks,

Wes

Use sudo when editing and saving files using the LiveCD. You don't need a password.

Thank you very much for the solution, cariboo907. I'm back in business and being a little more careful in editing this file.
