Editing GRUB to get other OS to boot error...

[rrfish72]

Trying to get Mandrake to boot but when it is selected there is an error that tells me: ERROR: Cannot boot selected partition. The boot loader GRUB is located on the hda2 which is handling the boot process. This is the bootloader that is being edited.
Mandrake is installed on hda5 whch I believe is the only other partition that is bootable with a OS on. I will try other partition #'s and post back if I am successful. I already tried (hd0,5) and (hd0,3). I looked up this info - (hd0,0)=1st partition, (hd0,1)=2nd partition, (hd0,2)=third partition.... and the hd0 is the selected harddrive - where if there were other harddrivies they would be hd1, hd2.....
I am posting menu1st from grub to see if anyone sees whats wrong with the info. This is the only OS that does not boot. Any suggestion appreciated.

kernel (hd0,3)/boot/vmlinuz-2.6.8.1-10mdk root=/dev/hda5

Isn't this suppose to be like this:

kernel (hd0,3)/boot/vmlinuz-2.6.8.1-10mdk root=/dev/hda4

Unless hda4 is a swap partition.

Mmh ... if you're positive mandrake lives on hda5, I'd rather try

kernel (hd0,4)/boot/vmlinuz-2.6.8.1-10mdk root=/dev/hda5 ...

(that's assuming mdk does not have a separate /boot partition)
