I am very familiar with grub but I can't get my root hd's mbr to work properly. For now, I have a CompactFlash disc acting as a grub boot disc. This happened while preparing another HD for a linux dist. Somehow I must have gotten my HDs mixed up and fubar'd my boot drive.

In grub prompt (within ubuntu):
root (hd0,1)
setup (hd0)

rebooted, but no banana...continual boot loop. The Grub text comes up and "grub loading 1.5" before the screen goes blank and POST reappears.

I cant access grub menu while booting from root drive either -- tho grub menu on CF disk is fine. I verified that my boot drive was hd0 by using find on a known initrd filename...only hd0 came back so I know I am targeting the right drive.

I just got the idea I should recheck the grub images on my boot drive.

well if you moved your drives around did you let bios know that too.?

My bios is set to automatically detect the drives. The order has not changed either. If you are referring to boot order, I have confirmed I am booting from the proper disk...both in bios boot order menu and by hitting F11 which gives me a BIOS boot menu during POST.

Not what I meant did you move any of your drives to different ata slots or different ide slots. this would cause this. bios would rearrange the boot order name. sda1 sda2 or sdb1 or sdb2 yes F11 would give you a boot choice but grub would look to bios for boot devices and it would not match.
down load super grub and as long as there is a /boot/grub/menu.1st it will find it and give you a choice to boot it.
