Hi, I have MacBook air (2012 model i think). I tried to install windows 7 64 bit using bootcamp. On the first windows boot and before installing boot camp drivers windows was fine. After installing bootcamp drivers and windows restart the windows came up to a black screen and stuck forever. When I uninstall graphic driver (intel HD 4000), windows is good again. Tried to reinstall different graphic drivers versions - didn't work. searched internet everywhere and didn't find any solution. please help!
