Wait... what the heck's the difference between 2006 Mac Pro and 2007 Mac Pro?

TheSpaz is right about the versioned files causing the problem. MS did not use their usual versioning habits for the introductory releases of Win7. Usually they have anytime upgrade options on their retail DVDs. That means that there are multiple images on the DVD which are triggered by different COA classes. This is what is usually causing the problems and I expect that to happen again as soon as the market settles for Win7.

I'm not going to bother responding to you here again after this: I know that a retail DVD and a burned one are not the same. I've already been corrected (and admitted I was wrong) by nanofrog on what the differences are, so anything you say is redundant. You did not explain it once, nanofrog did. I think our problem here may be semantics, though – what I mean by 'I know the difference' is that I know my burned DVD is not automatically exactly the same as a retail disc. However, beyond that, I did not know that the retail discs had all the versions on it, and a modification to the ISO. There. I'm done here.

I explained to you in this and other threads that booting from a retail 64bit disc doesn't work on our early machines and you were confused because yours booted just fine. I don't know all the technical reasons like nanofrog, I just know that it has an extra partition on it and that confuses the computer. Basically, to get around it, all you have to do is burn a DVD with only the OS partition.

I'm sorry that I don't know all the technical terms to describe what I was talking about. The fact is, I know that the retail disc doesn't work unless you modify it by burning a copy. There are tutorials everywhere about it. I'm not the only one who has had to do it. To think that you got a special computer is kind of absurd.
