You're there, biffer -- that command is using gedit to open up your menu.lst so that you can edit it. I think you just need to learn about grub and the menu.lst and what each line in there is all about. For example, that every line starting with "#" is just a comment, to be ignored by grub.
And it is
complicated, or can be! Check out the GRUB manual: http://www.gnu.org/software/grub/manual/grub.html
And do some Google searches about how to edit your menu.lst file.
And look for some examples of other folks' menu.lst files, especially folks who are dual-booting or multi-booting.
For example, I'm using Debian to boot Debian Lenny, Mepis 8, Mint Elyssa, and Ubuntu Hardy, and here is my menu.lst in Debian, customized by me:
- Code: Select all
color cyan/blue white/blue
title MEPIS at hdb1, newest kernel
kernel /boot/vmlinuz root=/dev/hdb1 nomce quiet splash vga=791
title MEPIS at hdb1, previous kernel (if any)
kernel /boot/vmlinuz.old root=/dev/hdb1 nomce quiet splash vga=791
title MEPIS at hdb1, kernel 2.6.27-1-mepis-smp
kernel /boot/vmlinuz-2.6.27-1-mepis-smp root=/dev/hdb1 nomce quiet splash vga=791
title Debian GNU/Linux, kernel 2.6.26-1-686
kernel /boot/vmlinuz-2.6.26-1-686 root=/dev/hda1 ro quiet
title Linux Mint, kernel 2.6.24-23-generic
kernel /boot/vmlinuz-2.6.24-23-generic root=/dev/sdb7 ro quiet splash
title Ubuntu 8.04.2, kernel 2.6.24-23-generic
kernel /boot/vmlinuz-2.6.24-23-generic root=UUID=c80c7227-b542-4b2d-8fed-f15e38694df3 ro quiet splash
Note that unlike Ubuntu and Mint, the Debian menu.lst doesn't have a bunch of lines starting with "#" but of course I could add some to provide some comments about what each line or section is all about...
You're on the right track, though!
