The Windows Support Software (drivers) for Boot Camp on a computer running Snow Leapard are on the Snow Leapard Install Disk. There is no Windows Support Software download for these drivers.
You should follow up in the Boot Camp forum https://discussions.apple.com/community/windows_software/boot_camp
Many thanks for the reply. My only concern is that I am using Mountain Lion (OSX 10.8). Are the drivers on the snow leopard DVD still valid? Should I just boot my computer and start it from the Snow Leopard DVD? I am asking you this simply because I will not be able to access any Windows 7 screen, since everything turns black as soon as Windows starts.
I looked through all the discussions, but I have not been able to find anything similar to my problem. Am I doing something wrong here? I am really stuck here! ;(
The Mountain Lion Windows Support drivers are available from within Boot Camp Assistant as a download. Start Boot Camp Assistant and select the option to download the Windows Support Software. Follow the instructions for saving the downloaded support software. When you boot into Windows make sure the device containing the drivers is inserted into a usb port and your Windows dvd is not in the computer. Windows will boot from your installed Windows on your hard drive and it will install the support software from the usb tick.
You should visit the Boot Camp forum where installing Windows and the Windows Support Software is explained in hundreds of posts.
And here is the Boot Camp help files in case you were unable to find them.
Thanks again for your reply. Maybe I have not been really clear on what my problem is. I have followed hundreds of Apple official and unofficial instructions. Of course I have already downloaded the windows support software from inside the bootcamp assistant and also on my computer extracting then the Drivers folder and copying it on the USB disk. This is not my problem. My problem is than when the installation is finished, I extract my Windows installation DVD and I try to start Windows from its partition, my screen goes completely black and I cannot do anything from there. So I can' t actually open my USB. My boot manager, I have NO clue why, doesn't recognised the USB even though it is connected directly onto my Mac and not on a USB hub.
I hope I have been clearer this time on where I am stuck.
