Dowloaded ISO, burnt to DVD. Trying to install on Virtual drive using MS Virtual PC. Gets as far as starting "Expanding Windows Files (0%) and thats it. Tried burning another DVD of same image, exact same problem. Downloaded new ISO image, burnt new DVD at slowest speed, exact same problem. Posts seem to suggest drivers etc could be problems but pretty crap installer (doing custom install not upgrade) if that is the case and it doesn't bother telling you! Thought W7 was meant to be a huge step up from the vile Vista?
