Thanks for clearing that up Goalque. Honestly, don't know what we'd all do without the generosity of people like you, Nando, Enjoy. 

For me, I'd be stumbling around in the dark without "light and pixels."

Hi all,

I'm having a problem here. After going through the steps, I can't boot into bootcamp after applying the apple_set_os.efi under reFind. It always stucks in a blue screen, however, booting into safe mode in windows is possible and it do shows two gpu under the device manager. Any one knows what's going wrong? By the way I'm using Macbook Pro Retina 15' mid 2015 with an amd dGPU. Sorry for my poor English.

You missed the step 0:

0. [GT750M/M370X/RP4xx 15" MBP only] Prior to booting Windows run 0xbb's ./gpu-switch -i. (macOS) or integrated.bat(Windows).  This sets the Apple gmux to wire the internal LCD to the iGPU when you reboot your system [into Windows]

It appears that I'm getting Video_TDR_Failure atikmdag.sys

Are you applying the integrated.bat prior to apple_set_os.efi? Works well with my Mid 2015 15" MBP (M370X). I guess your rEFInd is not correctly configured, I don't use it.

What's your eGPU/enclosure and Windows 10 build number?

Some cards/enclosures may need Thunderbolt connection delay as well or plugging in the other TB port.

Actually I don't have an eGPU device, what I am trying to do is letting my macbook to use both GPU while booting into bootcamp, is it possible?

Yes, it is possible. Both M370X and Iris Pro will be visible & active on Windows 10 if you follow the steps precisely under "USB stick creation procedure" & "Performing the Windows boot".

So, I still get the exactly same error with the code video_TDR_failure. I've follow all the steps and also uninstalled reFind, using the usb stick to boot. Any ideas?

You still haven't answered my questions:

1) What's your Windows 10 build number?

2) Did you run integrated.bat (as administrator) prior to apple_set_os.efi selection from the USB stick?

OS build : 14393.1198

I applied both integrated.bat and ./gpu-switch -i on windows and mac, but neither of them worked.
