I did install Windows 7 64 bit on my ex. Windows 8 pro Asus x551c "Ultrabook". The CD with the drivers isn't useable since its a windows 8 only DVD-Rom. I got the Wi-Fi and other stuff running and already tryed 3 of the Intel-HD Graphic drivers for win7 64Bit i found with google. No one was compatible with my pc. Any suggestions how to get this running? I hate windows 8 and dont want to get forced to use it.
