I currently have a pc with one hardrive and windows xp installed. I have a free copy of Windows 7 from my school that I would like to install on a new hardrive that I will ad to the system. (1) Is it possible to do this without affecting the programs I currently have installed on my original hardrive? (2) Would I have a choice to boot from either drive? (ie. the original xp drive or my new win 7 drive?)

Thanks a ton.
