Indeed, it should use the same one.
You may need to play on DX7 though instead of 9.
On another note, I am mildly surprised that Loki is not winning this poll.
EDIT do NOT partition it into a Fat32 file by the way, use the other method (more stable). If you can, give the W7 partition as much of the harddrive as you can manage so it can properly think. My 600gig iMac for example I split 250 of it to my bootcamp, this way you can jack up the virtual memory etc and not worry about lack of room and install whatever you want. Better too much then too little, you really only want to do this once, heh.
