Is anything missing?

Two things. Confirmation that there really is a GRUB in /dev/sdb1's boot
sector and not in /dev/sdb's MBR. And you forgot to show what you added
to your F10's grub.conf.

1. I told it to put it in the MBR.

That would be /dev/sdb = (hd1) and not /dev/sdb1 = (hd1,0).

The string 'GRUB' exists in the MBR, but
there was a grub 2 install there prior from a mint8 install.

2.:
#26
title Fedora 12 64 bit from sdb by chainloading
rootnoverify (hd1,0)
makeactive
chainloader +1

The comment is wrong. It tries to chainload /dev/sdb1 not the MBR.
The "makeactive" or "makeactive 1" typically is not necessary.

Do you see (hd1) in your F10's /boot/grub/device.map?
And what does /boot/grub/device.map on /dev/sdb1 contain?

I played with that some on the f12 disk, and yes, f10's device map is in
order, all bootable disks are listed in sata jack order, skipping the
Terrabyte drive I use for amanda.


Thanks Michael.
