I have been trying to install Windows 7 X86 RC1 on my brand new early 2009 iMac and have been having the same problem every time. Initial installation goes very smoothly, but all the trouble begins when I load the Boot Camp setup.exe from the Leopard disc. During Boot Camp installation I get a compatibility warning about some of the Apple Boot Camp drivers working correctly with this version of Windows. If I go ahead with the installation then what happens is I get a BSOD and then Windows becomes un-bootable. This is repeatable as it happens every single time I do the installation. Things initially seem to work up until I load boot camp assistant from the Leopard install disc, so I'm wondering if there are other drivers available that play well with Windows 7 for my iMac that I can try? I've followed several Boot Camp tutorials for iMac with Win7 and am pretty sure I am doing everything correctly, but things just aren't working. Any help is welcome!
