I have Windows XP Pro installed. I also have the beta version of Vista. I never got around to installing vista but since i have an extra hard drive i thought i would give it a shot. I unhooked my raptor and put in another hard drive. I installed Vista to it without a hitch. I then decided to go back to my old configuration. I removed the hard drive with Vista and hooked the raptor back up. Now windows will not boot. I gets to back up cmos and then stalls. Or it stalls at verifying pool. I put the vista hard drive back in and got the same result. What could be the issue?
