I have a problem and i wish if you could help me with.
I have an iMac Early-2009 ( 2.66ghz C2D / 4GB 1333mhz RAM / GeForce 9400 256mb ) with Mountain Lion 10.8.4
The problem is that, i can't install the drivers from the bootcamp app ( the one from the bootcamp itself app, where you need a USB to download it)
i've already partitioned the HDD, and installed succesfully a Windows 7 Ultimate 64bit.
But there's one little issue, when i try install the drivers i downloaded before on my USB, it says that "Bootcamp x64 is unsupported on this computer model".
BUT, what? i've installed correctly the Windows 7 64bit on the iMac.
I can't install anything, but only graphics driver. ( manually)
I searched in every forum trying to resolve my problem, i've read that you can install it from de DVD with Snow Leopard that came with the computer
but that disk is broken; it's annoying because it seems that is the only solution , with that resulting on a dead end.
I could install my NVIDIA drivers, using the ones from bootcamp drivers, BUT USING THE WIN_32 version because the WIN_64 was unsupported by my machine. ok, i could install the drivers and was the 263.03 i think.
Now i want to upgrade to my lastest drivers ( 320.14 WQHL ) and says that can't detect my gpu. but the old driver that came with recognized it with no problems. I tried also auto detect GPU, and the same drivers but no result.
Anyway, the main problem is that is "Bootcamp x64 is unsupported on this computer model". with a Windows 7 64bit copy installed on the bootcamp partition. this is ******* me off
I sucessfully installed on my Macbook Pro Late 2008 ( C2D 2.06ghz / 8 GB RAM / 9600m GT ) and everything fine, a Windows 7 64bit. installed the drivers and everything fine, even accepted the lastest drivers (320.14 WQHL) from nvidia. but that was on Mountain Lion 10.8
but since 10.8.3 only lets you install only 64bit, i can't search for a copy of win32bit and install it because, it's going to be the same problem anyways.
So if you could help me out with this *** problem.
