SATA/IDE and GRUB Dual Boot

[Captain Potter Fujichan]

Hi,
I'm trying to set up a dual-boot using a SATA harddrive with WinXP and a IDE harddrive with Ubuntu 10.10 Server CLI. I'd like to use GRUB in order to do this. I plan on configuring GRUB on WinXP. Could somebody guide me through this? I know a fair amount about these two OS, but I simply can't process how to do this. Both operating systems are already installed.
Thanks!

Edit: I have successfully put in the hard drive, but i'm still having some issues with switching between operating systems. I really don't want to have to disable the IDE channel every time i want to go to SATA and vice versa; is there any simple way to install GRUB on either OS?
