So I have been wanting to install Windows 7 on my Alienware but I've noticed that their isn't any applicable drivers for Windows 7 so I went back one generation to the X51-R2 drivers and they have Windows 7 drivers. Will the X51-R2 drivers work or not? Will the X51-R3 Windows 10/8.1 drivers work with it? I also know that I have to turn off Secure Boot and turn my BIOS setting to legacy for it to work. I am also running Windows 8.1 Pro.
