This program is a real dream to use. Once I had filled in all the correct info to the recommended instructions via http://forum.imgburn.com/index.php?showtopic=11194 it worked very well. I had one question without trying it. What is the difference between this method and the copy method used in programs like Nero. I understand that certain programs don't boot very well if they are cut & pasted but my copy of Vista copied via Nero and boots fine. This is not a criticism as I had to buy Nero and this one was free; thanks again.
