That's a great job! Would it be possible to automate this? Patch the bootloader without installing Linux?

It would be great to develop a tray icon for Windows, so we can switch between nVidia and Intel gpu.

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:

6.1 diskpart

6.2 select disk 0

6.3 clean

6.4 convert gpt

6.5 create partition efi size=200

6.6 format fs=fat32

6.7 create partition msr size=128

6.8 create partition primary size=102400 (You might want to set your own size here)

6.9 format fs=ntfs quick label=Windows

6.10 exit

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:

10.1 create partition primary size=204800 (Set your own size here)

10.2 format fs=ntfs quick label=OSX (Don't worry about the filesystem, we'll reformat it using Disk Utility later)

10.3 exit

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:

19.1 Select your keymap by typing "loadkeys keymap_file (available keymaps are located in /usr/share/kbd/keymaps)"

19.2 Launch gdisk

19.3 Create a new partition for your root mountpoint

19.4 Create a new partition for your swap mountpoint

19.5 Creae a new partition for your boot mountpoint using EFI boot

19.6 Create a new partition for you extra boot mountpoint using EFI boot

19.7 Format your newly created partitions (mkfs.ext4 for root, mkswap for your swap partition and mkfs.vfat for your EFI boot partitions)

19.8 Mount your root partition on /mnt and your first boot patition on /mnt/boot/efi (You'll need to create this folder). "swapon" your swap partition.

19.9 I used a USB to Ethernet adapter, and the installation CD configured it automatically. If you need to configure wireless settings, please refer to the ARCH Wiki Guide: https://wiki.archlinux.org/index.php/Wireless_network_configuration

19.10 Edit the /etc/pacman.d/mirrorlist and comment out any unnecessary mirrors.

19.11 Execute the following command "pacstrap /mnt base"

19.12 Wait for the base packages to download and install

19.13 Generate your fstab file by issuing the following command: "genfstab -U -p /mnt >> /mnt/etc/fstab"

19.14 "chroot" into your newly created environment by typing this command: "arch-chroot /mnt /bin/bash"

19.15 Uncomment the needed locales in /etc/locale.gen, then generate them with: "locale-gen"

19.16 Execute the following command: # echo LANG=your_locale > /etc/locale.conf (where your_locale matches your keyboard and language settings)

19.17 Create a new initial RAM disk with: "mkinitcpio -p linux"

19.18 Set your root password with "passwd"

19.19 Create a new user for yourself with the following command: "useradd -m -G wheel <username>"

19.20 Set password for your user with "passwd <username>"

19.21 Upgrade pacman db with "pacman-db-upgrade", allocate the repositories with "pacman -Syy" and Install the sudo package with "pacman -S sudo"

19.22 Add your newly created user to the sudoers file located in "/etc/sudoers"

19.23 Switch to your newly created user with "su <username>"

19.24 Go into your user home directory "/home/<username>"

19.25 Install packer dependencies with "sudo pacman -S base-devel fakeroot jshon expac git"

19.26 Create a new directory to download pkgbuild "mkdir pkgbuild"

19.27 Install wget and vim with "sudo pacman -S wget vim"

19.28 Get into the pkgbuild directory and run "wget -c https://aur.archlinux.org/packages/pa/packer/PKGBUILD"

19.29 Execute the "makepkg" command inside that directory

19.30 Install the newly created package with "sudo pacman -U packer-*-pkg.tar.xz"

19.31 Go up one level

19.32 Download my pre-patched, pre-compiled grub2 binary from "http://www.nocreado.com/grub-git.tar.gz" (this one includes Andreas Heider patch to trick the bootloader with "apple_set_os")

19.33 Run "tar xvzf grub-git.tar.gz"

19.34 Switch to the grub-git directory

19.35 Run the following command: "makepkg -si --skippgpcheck" to install my version of grub

19.36 If everything went fine, then you're ready to install and configure grub. First thing you'll need to do is tweak the "/etc/default/grub" file and add "libata.force=noncq" to the GRUB_CMDLINE_LINUX_DEFAULT parameter, it should end up looking like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet libata.force=noncq"

19.37 Install grub with the following command: "grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=grub --recheck --debug"

19.38 Generate your grub configuration file with the following comand "grub-mkconfig -o /boot/grub/grub.cfg" (This should reconize your vmlinuz images and your Windows installation).

19.39 If everything went well, go to your / and create a new mountpoint for your extra boot partition (e.g. sudo mkdir /loader).

19.40 Mount your patition there, switch to that folder.

19.41 Touch a file named "mach_kernel"

19.42 Create the following path inside the folder: "System/Library/CoreServices"

19.43 Switch to that newly created directory (CoreServices) and vim a file named SystemVersion.plist with the following contents:

Edit: Please refer to https://wiki.archlinux.org/index.php/MacBookPro11,x for the file contents configuration

19.44 In that same directory, generate your boot.efi image by issuing the following command: "grub-mkstandalone -o boot.efi -d /usr/lib/grub/x86_64-efi -O x86_64-efi /boot/grub/grub.cfg"

19.45 Reboot into OS X.

19.46 Mount your extra boot partition with diskutil "sudo diskutil mount /dev/diskXsY"

19.47 Bless your new partition with the following commands:

sudo bless --folder=

--file=/System/Library/CoreServices/boot.efi --setBoot

sudo bless --mount= <dev device=""> --file= /System/Library/CoreServices/boot.efi --setBoot

19.48 If everything went well, restart your computer holding the option key. You should be able to reach your arch installation by selecting the "efi boot" Volume and Arch Linux from the grub boot menu.

19.49 Once back in arch, download and compile https://github.com/0xbb/gpu-switch

19.50 Reboot into OS X, select the new EFI Volume "Arch Linux" as your main disk in the Startup Disk Applet.

19.51 Reboot your computer, you should be able to reach Grub without holding down the option key

19.52 Boot into Arch, execute sudo ./gpu-switch -i

19.53 Do "sudo reboot"

19.54 Once you're back in grub, click the "c" key to enter the console, type the command "apple_set_os" in the prompt.

19.55 Click "esc" and boot into windows, You should be able to see 2 display adapters!!!

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've also tried this using grub, same blackscreen result:

Iris Pro is working Flawlessly in Gentoo - Arch.

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. This is how my .nsh code looks like:

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!

Have you seen this post: Win7 x64 booting natively via EFI (no BIOS emulation) - Page 42 - MacRumors Forums?

And tried their tool? I was gonna test it later today..

https://github.com/0xbb/gpu-switch

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!

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!
