I think in an earlier post he said he is still on grub 1.97.
Ed, how are you attempting to edit menu.lst?  You have to do it with
sudo so that you have permission to save it.
sudo gedit /boot/grub/menu.lst

If using grub2 then I think there is a simpler way to change the
default boot.  Edit the cfg file
sudo gedit /etc/default/grub
and change the value of GRUB_DEFAULT to the one you want (the first
one is value 0). Then
sudo update-grub
It does need to be re-done if a new kernel is installed as the number
will change.
