So I made the assumption that your part layout was /dev/sdb1 f10 system, /dev/sdb2 f12 system.

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.
Don't do anything till we have another exchange of dialog, my previous message didn't take into account your non simple partition layout.
Humm, I didn't read this far, so I did it anyway. Sorry.

Thanks Will.
