I have several distros on two hard drives chainloaded in the Suse(hda6) Grub. Debian is at hda1 and its bootloader was overwritten by Suse (MBR at hda).I can't boot into Debian.
I navigated in Suse to the Debian menu 1st and copied the bootline into the Suse menu 1st but it just gives me Error 15: File not found when I try to boot to this.
I need to make the Debian grub point to root hda1 and then I can put it in Suse's menu 1st but I don't know how.

can you post your /boot/grub/menu.lst here? would be a bit easier to tell you what to edit

Here is the Suse menu 1st...
