Finally!!! Alienware M18x R2 with Dual 980M SLI

Here are some basic steps to upgrade Alienware M18x R2 to Dual 980M SLI successfully. This configuration only tested Windows 8 or 8.1, it will not work with Windows 7.

1. Before replacing card, go to system Bios (keep your old graphics card inside system or not any graphics card installed). Then click on Boot tab, UEFI = Enabled, Legacy ROM = Disabled. F10 to save bios and Exit. After then turn off system.

2. install Single or Dual 980M.

3. Now system will post. You will get text on screen something like, Checking devices, can not find boot device press any key to restart.

4. You will need to create bootable UEFI windows 8.1 installation USB flash drive.

Rufus is a small utility that creates bootable USB flash drive for Windows 7 or 8. What makes Rufus different is that it offers 3 different partition scheme to target the system type, such as those UEFI based computers. You can make a bootable drive that can directly boot off on a UEFI computer without turning the Secure Boot off. It’s free

1. Plug in USB flash drive,

2. Launch the program. Since it’s portable, you can simply just download and run it.

3. Check the option “Create a bootable disk using: ISO Image“, and click the icon next to it to pick up the ISO image file.

4. Select “GPT partition scheme for UEFI computer“.

Before you click Start button, check to make sure the settings are selected to similar like Figure

5. Click Start, and dont stare (it will only take few min ). take out USB drive when done.

5. Connect USB flash drive to system and press power button, now you will able to Install windows 8.1.

6. That's all you need to do you to do.

I do specially thanks to @godfafa for procedure. @Mr. Fox Actually your suggestion about UEFI was correct, if we did more research on it then we can able to achieve it early. Also credit goes to @j95, @svl7, @Prema, @Cloudfire(specially to keeping struggle Alive ) And finally @GTO_PAO11 for Cheering .

I will update more when i get time to do.
