Ok. I have Windows 7 Ultimate 32 bit. I want to install Windows XP on this same computer, but I hear you can't successfully have a dual boot for 7 & XP? I don't fully understand what is necessary, I hear there are issues with having the two together. I don't want to fuck my only computer up, so... Any advice? What order do I install them in, and how? Also, my computer is NOT compatable with Virtual PC.
