Angels have the Phone Box
After the Windows graphic appears on the screen it should immediately show Preparing, then shortly afterwards, give you the option to download and install updates or not (select yes). It should not sit at the Windows graphic very long at all. I don't know how fast your internet speed is, but the ISO takes about 15 minutes on a 60MBps connection. I am wondering if your download is no good for some reason? I usually get the ISO from the MSTechBench page. It's important to get the same version and bitness of your system, or it won't work. Perhaps you can try that, and just save the ISO to your desktop. Then, right-click and select Mount, and run setup.exe from there. I just did this on a system two days ago, and it worked fine.
