my son crashed his machine that had XP home on it, he then had a trial or eval disk for vista premium and loaded it. There was an auto disable on vista and it eventually died. He bought a copy of MCE 2005 and when he tried to install mce it wouldn't let him since there was a newer os installed. He then tried to reformat the hdd to start over with the mce but has not been able to accomplish that. he has two hdd but has tried to disable main drive and boot to drive 2 but still no luck. I'm in California and he's in Colorado so I'm at a loss as to what to tell him. He does not have access to any on line machines so I have been advising him via phone. Anyone with a thought about how he can dump everything and install the new os?
