Windows 7 64 bit not booting with Intel iMac (Mid-2007 model)

The Scenario

I have a 20"Intel iMac running OSX Leopard. The computer was dual booted using bootcamp to run win xp 32-bit. I have just erased this partition and installed Windows 7 Ultimate 64-bit. When I insert my leopard disk to install bootcamp drivers it fails with the error message:

'Version Does Not Support 64-bit Bootcamp'


I also have a brand new MacBook Pro running Snow Leopard. I was able to partition the hardrive on the MacBook and install a copy of Windows 7 evaluation version and then install bootcamp drivers from the Snow Leopard disk.

Question 1

I can't understand why the iMac cannot install the 64bit drivers from the leopard disk, is this because Leopard is not full 64-bit?

Question 2

Is the reason that the MacBook can support the snow leopard 64-bit drivers to do with the fact that it is running an evaluation copy of windows 7?

Question 3

If I upgrade the iMac to Snow Leopard will I then be able to install the bootcamp 64-bit drivers on that copy of Windows 7 Ultimate? Will I have to completely reinstall windows 7 ultimate in order for windows to recognise the snow leopard upgrade to full 64-bit?

Very Confused

Help greatly appreciated.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Just to quote from a previous question on this:

Microsoft Windows Vista 64-bit editions work with certain Intel-based Mac computers via Boot Camp, which is included with Mac OS X v10.5 Leopard.

So it's most likely not supported for you iMac.

But according to Chris you can:

Actually you can, and here is the blog post detailing how!

Windows Vista x64 and here is the addendum for Windows 7 x64

This might not answer all your questions, but it does explain why you're having problems. I guess the answers would be: No, No and No...
