IOW take a look at the path '/boot/grub/'. There should be a menu.lst or
a grub.cfg.


If you're using GRUB2, as I unfortunately do, you should change /usr/sbin/update-grub to (something similar) as ...


#!/bin/sh -e
exec grub-mkconfig -o /boot/grub/grub.cfg_$(date +"%b-%d-%Y_%H-%M-%S")
"$@"

... if you don't do it, resp. you try to follow the idea of GRUB2 to use
all those 'special' files, you won't be able to configure and keep your
personal, customised menu.

Please post your /boot/grub/menu.lst or your /boot/grub/grub.cfg.

2 Cents,

Ralf
