I have installed Win7 on my Mac and it works fine other than the sound issue. However, when I tried to start up Snow Leopard using the option key, I get "EFI Firmware" and "Windows" as the the two options not the "HD Macintosh". anyway, when I select to start the Mac side, it takes about 10 minutes to start up-seriously. Once it starts up, everything is fine. Windows starts up immediately when I select it. I tried talking with Apple support but that was no help as they blamed it on the fact that Bootcamp does not support Win 7 at the moment. Any ideas?
