I just finished installing windows 7 64 bit but when i insert my leopard disc in to install the drivers it says that my model mac doesnt support x64. I have a 20" 2.66 08 model i thought this model was compatible with windows 64 bit. Any other way to install drivers? am i doing something wrong?
Some iMac models are allowed to run x64 OS's through Boot Camp, why, only Apple knows.
Truth is, your system is capable of it. There is a work around, and it requires you to type some commands in "Command Prompt" in Windows, but after that you can easily access and install the respective x64 drivers.
Search in the MacBook Forum, there is the guide to add Windows 7 x64 to your machine. The procedure is the exact same thing, just different model.
