I have downloaded W7 from a few places and I cannot get the ei.cfg trick to work. I have tried two ways. BTW, I use magic ISO, which I am starting to believe is the problem. I d/l the ISO and open it with MI, then delete the ei.cfg file and save as an ISO file, burn to DVD. That gives me a blank DVD. The other thing I tried was to load the ISO and then extract all the files, delete the ei.cfg file and then create a new ISO and burn to DVD. This second method gives an error when I boot up. Also, when I burn the originally downloaded ISO, it works just fine. One other thing - I am using a DVD+RW to do all the above.
