I was thinking about that last night! Maybe if we compile this script as a grub module or executable file. I don't see any linux specific functions in the code. I'll give it a shot later! Another bug I found is that Hibernate/Sleep isn't working correctly in Windows. Maybe the "null" driver get's installed based on the computer firmware or something.

¡WARNING! This process will require you to wipe out your hard drive, you might get it to work with pre-installed systems but I haven't had the chance to do so. As of now, brightness is not working on bootcamp, I'll need to research the issue. Detailed step by step guide: 1. Create a Win 8.1 EFI bootable flash drive using Rufus. 2. Create an Arch Linux bootable flash drive using Rufus. 3. Create a OS X Yosemite bootable flash drive using createinstallmedia. 4. Boot your computer using the Win 8.1 install flash drive. 5. When you get to the Windows install screen, press shift+F10 to get to the MS Shell. 6. Execute the following commands: 7. Proceed with Windows Installation 8. Once in Windows, click on start menu then type "cmd" 9. Launch diskpart again 10, Create your OS X Partition with the following commands: 11. Restart your computer and boot into the OS X Yosemite installer 12. Launch Disk Utility 13. Erase your newly created partition using HFS+ as the filesystem 14. Close disk utility and install OS X in there. 15. Boot into OS X. 16. You'll now have both Windows 8.1 and OS X installed in EFI Mode, now you'll need to install Arch Linux. 17. Boot your computer into the Arch Linux installation USB. 18. Launch the Arch Console. 19. Execute the following commands: Now, the first time I installed the bootcamp drivers I just selected the windows partition while holding the option key at startup. This to avoid the dual video card config. Then I deactivated the nvidia card, executed the gpu-switch command, booted into windows and installed the newest intel drivers, this is how my device manager looks like: Enjoy! Greetings Jose M.

I Got it to Work!! I'll describe my procedure in the next post, in broad terms, all you need to do is: 1. Wipe out your Hard Drive 2. Install Win 8.1 EFI Mode 3. Install OS X 4. Install Arch EFI Mode 5. Install grub on arch applying the following patch: [PATCH] Add apple_set_os command 6. Set your grub boot drive as your default in OS X startup disk applet. 7. Modify grub.cfg and compile your new bootx64.efi bootloader. 8. Download and compile https://github.com/0xbb/gpu-switch 9. Run sudo ./gpu-switch -i 10. Reboot from linux 11. Start windows from grub loader. 12. Install Intel Driver!

I'll Probably need some help around here! So far I can boot to Win 8.1 using the Intel Iris Pro driver (5200) hooked to a "Virtual Display". Looks like the LCD panel is still hooked to the nVidia card with a Generic Driver. I've tried a couple of different things: Using reFind: Cloned the process outlined here: [GUIDE] 2012 15" Macbook Pro Retina + GTX560Ti@8Gbps-TB1 (TH05) + Win8.1 , however, the screen just goes black and I have to force shutdown my computer.

Update! I changed the nVidia driver in the Device Manager for it to use the Microsoft Basic Display Adapter. After the reboot, I was able to see the color I chose for the login screen. I tabbed twice, typed in my password and managed to get into the windows desktop! At first, it was using some type of "extended virtual desktop", but I managed to tweak some settings in the screen resolution applet to make the Color LCD my main desktop. I'm also able to reach the Intel Graphics Control Panel. Stay Tuned! - - - Updated - - - Hey Tre87! Actually, I found the hint to do this on those pages! Haven't had the chance to compile his code but I'll give it a go, I'll keep you updated!

Hey Guys! Sorry if this is not the appropriate forum, or if this has been done already (I found no related posts). Long story short, I have the Iris Pro on the 15" Macbook (Mid 2014 with dGPU) partially working on Windows 8.1. I created a triple boot installation (Mac, Win 8.1, Arch Linux), patched Grub to fake the "booting-into-os-x" procedure, and forced the iris pro 5200 driver installation on windows. So far, I can only see the two devices working in safe mode, see screenshot below: I have tried uninstalling the nVidia card drivers and something weird happens after windows load, looks like there's a secondary screen, with a different resolution to the right of the "main" screen. I can move the mouse and everything, but I can't log in. If I disable the nVidia card, I just get a black screen after windows load. Any ideas? Suggestions? I was thinking maybe I could get my hands dirty with nVidia CUDA and code an applet to manage this stuff. I'm good with C/C++ but I don't know if that's possible at all. I can reveal more details if you want. Thanks! - - - Updated - - - This is basically the Grub hack: http://lists.gnu.org/archive/html/grub-devel/2013-12/msg00442.html I was thinking, maybe it's possible to completely disable the nVidia card from the Grub EFI console. Does anybody have any experience with that?

Thanks tre87! I'll definitely give it a shot then. I was going to get a 4K screen anyways, so let's see how it goes! In terms of performance loss, when you use the internal screen using the drag n drop method. How much do you think you're losing? Around 20% or more? Greetings!

Hi there! newbie here. Just curious about something. After some research, someone said that the MBP internal screen can be used if you drag and drop the application from the external display (MacRumors Forums - View Single Post - 2013 15" Macbook Pro + GTX780Ti@16Gbps Thunderbolt2 eGPU implementation) Would you mind giving it a shot and verify if it's possible at all? Thanks in Advance!
