Lots of things you need to consider, one you dont want to break

Do you Chainload into mandriva aswell? is the Mandriva boot installed
to MBR /dev/sdd or in the partition /dev/sdd1?

Steps I would take:
:Reinstall grub to the MBR of /dev/sda and make sure that it has these 3
: devices

-grub prompt in f10-
device (hd0) /dev/sda //f10
device (hd1) /dev/sdb //f12
device (hd2) /dev/sdd //mandriva
root (hd0,0)
setup (hd0)

This did not return any errors, so I am off to try it.

And, and hour later, it failed, error 13. Invalid file format or some such
drivel.

The hour was because it decided to do an e2fsck on /usr, which is something
over half a Tb.

Option #1

:Reinstall grub to the MBR of /dev/sdb

device (hd0) /dev/sdb // This grub is isolated from the MBR one on
/dev/sda so I believe this is correct, I've never done something like
this personally, though I've messed around with grub alot
root (hd0,0)
setup (hd0)

: Make sure all your entries in menu.lst for f10 are correct

# Again I think this is correct, though I haven't done anything like
this, I have chainloaded into grub installed to a partition, but not
into one installed to another MBR on a seperate drive
title Fedora 12
root (hd1,1)
chainloader (hd1)+1

Now I have done this, and will try it. And this reverts to the grub screen
from /dev/sda in about 4 seconds, silently.

Why did you try that? root (hd1,1) expands to /dev/sdb2 which is not
what you had referred to earlier.

# load boot sector of first partition (sdb1)
title Fedora 12
rootnoverify (hd1,0)
chainloader +1

Assuming that F12's GRUB _really_ is installed in /dev/sdb1 and NOT the MBR.

And if it's installed in the MBR, you could boot F12 by changing the boot
order in your BIOS, then use "grub-install" to (re-)install the boot loader.
Make sure that you don't mix /dev/sda1 and /dev/sdb1 when running grub-install.

you may also need to edit /boot/grub/device.map to make sure that the device
mapping is correct. (Note: this is USUALLY not necessary)
