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.
Check this page for information regarding installing Windows 7 with the Intel Z170 chipset. Seems like a lot of work since Windows 7 drivers do not seem to support USB 3.0 during installation. And I would doubt the compatibility of Windows 10/8.1 drivers in general.
They might. The problem is not so much in the driver being compatible, it is whether the installer for the driver will allow installation in Windows 7. The installer may see Windows 7 and stop the installation since the OS is not Windows 10. You will be getting drivers then from other sources besides Dell. Hit and miss and the only way you will know is to try it.
