Burnt copy? Do I smell the old "got it from a friend"?
Not necessarily. Cause i have no "Official" DVD myself. I only have burnt copies downloaded from Microsoft. So dont go jumping to conclusions that just cause he says burnt copy that it is automatically a pirated copy. As there was Digital Distribution available for Win7 and it was more widely used than the actual media itself. Digital River and Microsoft teamed up for the Student copies that were downloaded and used with the USB Tool.
So in fact i would say that there is more than a 80% chance that the method used to get Win7 is via ISO form and downloaded from some source. Now the validity of the source is another thing. But we cant jump to conclusions. We must ask first.
I would say that is definately the issue. The one that was backed up was not made for this system. So of course your going to get all of these issues. The hardware doesnt match and the drivers dont match. Get a better copy of the Win7 Upgrade Disk and start the process over. Sorry i know it stinks, but that is what must be done to fix this. Win7 doesnt have a repair feature.
