That means nothing, you could have a high speed burn that works on some systems and not other. I didn't go into that because you indicated that you were using a technique to boot from an ISO file also and it had the same problem. If that's the case it likely isn't a burn issue, so that gets us back to trying the various cheat codes to find out what the problem is. You might also try booting in failsafe mode, which bypasses most hardware checking. You will not be happy running Knoppix that way, likely you mouse and network will not work (among other things), but at least you might see Knoppix boot. And you can try booting in expert mode and taking good notes about how you answer each question. That way you can try answering the last question before a hang differently, and knowing what the last question was before the hang might give you more insight on what cheat codes to try.
