seporate instances?

I was wondering if I could install parallels and keep the option to boot to windows XP as well? WHen i installed paralles it took over the windows partition and it only existed as a boot camp drive with parallels.. Which negated the ability to boot as an XP drive soley. I wanted to play my games on my windows drive that wouldnt play in parallels and since i couldnt run in XP mode but only in boot/disk parallels mode, I couldnt.

Is there a way to set up parallels so you can run it on mac mode but also retain the ability to run the seporate drive IE starting up in Windows mode only?
