OK so I tried using the EFI bootloader on my usb key without the EGPU connected and with it connected. My external graphic show on the bootloader, but again, i'M unable to select any partition to boot. Any key I press on my keyboad do nothing. Anyone has any idea what to do? or with another version of that bootloader to try?

Hello,

Thanks so much for your detailed guide! This is very helpful. I think my lack of technical expertise is hanging me up a bit, and perhaps the hardware I’m using. On the Mac side it’s working great, but on Windows, no go. I have the new 16” MacBook Pro, with the Razer Core X enclosure and a Radeon VII card. Having the error 12 issues, yet when I go through and disable the other recommended PCI drivers, it still doesn’t seem to work. Can you help me troubleshoot it? Thanks so much!

@Greg Batla Try the modified apple_set_os.efi boot loader [link].

Well I'm glad to see at least you can boot into windows, on my side I can't even archieve that! LoL

Little Update,

I just decided to remove my usb key and boot straight into windows without external EFI thing. (EGPU disconnected)

Little improvement is that I now manage to install AMD drivers (once I booted into windows and connected via hotplug the EGPU) and my graphic card appeared correctly in device manager, but saddly, with error code 12.

I tried reinstalling and retrying with different windows builds (1803,1903 and 1909) because I couldn't find the correct version mentionned in the tutorial by @itsage. They all, however, gave me error code 12 again. I'm currently on the os version 10.0.18362 Build 18362.

 

Looks like this is going to be hard!

@simon_jl Take a look at my 2018 Mac mini + RX 5700 XT eGPU setup [build link]. I'm currently using the modified apple_set_os.efi v0.5 and it's been working great in Boot Camp (Win10 18362.295). I have a USB-C portable monitor connected to the port next to HDMI and the Thunderbolt 3 cable to eGPU is the port next to Ethernet.

Thank you very much for the help!

I just can't explain it...... the error code 12 just dissapeared.

I forgot to set the default os to boot to MacOS in bootcamp so I woke up in the morning and started the computer with the egpu connected thinking it would boot in Mojave, so I went for some coffee and when I got back I was presented with the windows login screen and my 2 monitors connected to the eGPU where showing the windows desktop, awesome!

The next step is backup, backup, backup for my bootcamp partition (if you have any suggestion on this, it would be greatly appreciated!)

 

Again thanks to all who helped me, I finally got it running! Lets hope it'll last for a very long time!
