However, you may want to perform a repair installation of Windows XP to resolve the issues. Just keep in mind that repairing XP will cause Windows 7 to temporarily become unbootable until you reinstall the Windows Boot Manager.
I installed Win 7 some days ago, repartitioning my HD.
The installation runned normally, and Win 7 is also running normally, despite some beta-normal bugs.
But when I went back to XP, it was weird, first, I was greeted with some of that "New hardware found!" warnings, and Windows trying to install them. For some days, there was nothing else, but now, I'm getting some real problems, like the computer being VERY slow and freezing up after about 5 mins of use, no matter what I do.
Did someone else had such a problem? Is there some way to fix without reinstalling XP, BTW, XP refused to do the system restore.
I'm almost formating my whole HD and putting Ubuntu in it.
