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'
However
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.
