I'm trying to Downgrade the Dell Alienware 17 R4 to Windows 7 and like i'm having the same problem i had downgrading the XPS 8910 and The Alienware R5.
With the XPS 8910 and Alienware Aurora R5 i solved the problem Downloadin by dell the following ISO of WIndows 7: G13K9_PW4KGA00_W7SP1PRO64_ROW(DL)
This ISO it does not work on this Laptop(Alienware 17 R4). Basically when start the system with Windows PE it does not recognize the USB port so it lose the Installation media.....
I tried to Inject these driver into the boot.wim
But nothing has change when i start the Installation of windows from usb key...i lose the of usb ports and so the media with the installation of Windows....
I have to add the driver also in the Install.wim? There is the possibility to download the CAB drivers?
Tanks in advance for any HELP
Unlike the XPS 8910, which is Skylake, the Alienware 17 R4 is Kaby Lake. Skylake was the very last Intel platform with Windows 7 support.
Kaby Lake is Windows 10 only.
Here's Dell's official statement on OS support for 7th generation CPUs (aka Kaby Lake)
