This sort of thing tends to be because someone doesn't understand how
GRUB orders the drives (the first one is hd0, the second hd1, etc.), and
it doesn't care where they're connected. Yet, when someone installs
GRUB, they use a different scheme (/dev/hda or /dev/sda) and installs it
to the other drive, or points it to get its second stage files at the
other drive (inside the /boot/ partition), without realising it.
On systems that have removable drives, it really helps if whatever's hd0
is always going to be considered the first drive, and you put all the
GRUB stuff on it. This may mean changing BIOS boot orders so that
things like USB drives are later in the boot order.
One other thing that can mess up grub is if you tell the BIOS to
boot from another drive. This can change the drive ordering that the
BIOS reports. For example, if I boot normally, my internal hard
drive is hd0, but if I boot off a USB drive, then that drive is hd0.
I don't know if grub has this problem, but I remember that with
lilo, you had to tell it if you were booting off a SCSI drive on a
mixed SCSI/IDE system. It would assume that the IDE drive was mapped
as the first hard drive by the BIOS. I believe it would have the
same problem with a system with both SATA and PATA controllers, but
I never tried it.

Grub is bad period! I used a rescue cd and when up I typed grub and
it came up after a while and I typed this:
grub> root (hd1,5)
it said it was a linux partition
grub> setup (hd1)
here it wrote out a lot of things that included that it was putting
stage 1 on (hd1). I assumbed wrong that grub would use stage 1 on (hd1)
but it refuses to use it!
Grub will not ever boot from a stage 1 on (hd1) period.
To get grub to work I will have to put a stage 1 on the new (hd0) hard
drive. What a stupid system!
