I'm currently thinking about adding Ubuntu as a secondary operating system to my computer.

I currently have one small IDE drive that is housing Vista with a few smaller apps, and a larger SATA drives that holds music, movies, games, and important apps.

If I were to install Ubuntu, how difficult would it be to have it placed on the SATA drive, and have GRUB realize that there is one OS on the IDE, and one on the SATA?
