No clue if this is what you are looking for, but you could always boot in the live cd of uberstudent, mount the partition that you want to have grub installed, then grub-install --root-directory=/where/ever/you/mounted/it/to. Then reboot and then sudo grub-update.
For more details continue reading.
Put in live CD uberstudent, and go into the bios and change the boot order, or simply boot onto CD (if your BIOS supports that)
Then, once everything is booted up (Username:Password/uberstudent: ) You are going to want to list all the partitions on your computer. (This is assuming you have all the operating systems installed) You can check this with a GUI (gparted, conventiently on the live CD (thanks Mr.Ewen

) or through terminal.
sudo fdisk -lThis is where the tricky part is. You are going to want to find the root partition (I'm assuming you are installing grub on linux). If gparted has the mount point, you are looking for the one that has "/". If you are looking through the terminal, I'm not entirely certain, but I do know, its probably ext3 or ext4, and not linux swap that you are looking for. (Try the one with the star

boot) If you do not know, it's ok, because you can always kind of guess and check.
You are then going to want to mount the partition.
sudo mount /dev/sd[color=#40BF00]a6 /mnt[/color]
where the green is variable. If your linux root partition is sdb3, do that one instead.
What this does, is it takes the partition, and puts it on your live cd, so you can explore and see it. It should be mount on /mnt, so we can test that by typing
ls /mntYou should see a bunch of files like /opt /etc /usr etc. if you do, that's the right one. If not, then unmount it and try a different one
You unmount by doing
sudo umount /mntIt's important to precise it's umount, not u
nmount.
Once it's mounted, type in this command.
sudo grub-install --root-directory=/mnt/dev/sd[color=#00BF00]a[/color]
This essentially tells you to install grub, at the location of /mnt/dev/sda or sdb.
You are going to want to change sda or sdb to which ever your linux parition is on. You do not do sdb1 or sda3, just sdb or sda.
You are then going to want to do a restart. When booting up, (make sure you are booting up on a hard drive and not the CD) you should see a grub screen. If you do not, then try changing the hard drive, assuming you have 2, to the second hard drive, where you could have installed grub. (BIOS --> boot options --> make HD2 higher)
You should be able to see grub once all this is done. When you do, choose the recovery mode instead of the regular operating system, and when you see a blue screen with a grey box, choose the "update-grub" menu, let it do it's magic, and reboot again and you should be good to go

I hope this is what you were looking for
