So i'm trying to upgrade from vista 32 bit to 7 32bit using an official CD. Doing a clean install isnt something I want to do b/c I dont want to lose everything on my harddrive. When I do the upgrade I get the error "Windows could not prepare the computer to boot into the next phase of installation." I've tried disabling everything but microsoft services at bootup before installing, but to no avail. The compatibility checker thing doesn't come up with any problems before installation. I've got over 20gigs of space still on my harddrive, so I don't think that's the problem. I've also run the chkdsk utility from the command prompt, but I don't think it found anything. The windows compatibility checker first found issue with SCSI/RAID controllers, but an uninstallation of daemon tools took care of that and it doesnt come up with any other compatibility errors Any ideas to help?
