I'm trying to upgrade from Windows 7 to Windows 8, so I downloaded the ISO and burned it to a DVD.
However, when I try to run it nothing happens. I get the dialog asking me if I want to allow the program to run but nothing happens.
The disk works if I boot from CD/DVD. However, when asked if I want to do a clean install or an upgrade it tells me that I have to boot to windows and run the DVD.
Any ideas?
