Sorry, I edited that out from under you. I decided it wasn't a useful question; using a graphical linux installer deprives you of nearly every bit of useful information.

Installing it on it's own, seperate drive would be a good idea if you're not intimately familiar with linux, grub, and how the two work with each other. I never did like the idea of dual boot; when it works it works well, but if anything goes wrong you've you've potentially destroyed two operating system installs and are given no feedback about why...
