I being new and trying to fix my system to boot into windows automatically edited my grub.cfg file to point at the windows file. now the system won.t boot as I entered the wrong number in the line I edited. I was told that I could edit it from a live CD.

I can sometimes get to the file (actually only one time) but usually cannot. when I can get to it it tells me that I do not have permission to save the file. the other times it tells me that I do not have permission to view the root directory.

2 problems. My system is version 10 and the live CD is version 12. does this matter.
the other problem is version 12 is the new GUI and I can not find term which might help me bypass the problem I am having by using SUDO.

I think you should have to try boot repair and restore your grub .help.ubuntu.com/community/Boot-Repair – Jai Jun 26 '12 at 13:09
