Bootcamp Not working with eGPU In Big Sur
Since updating to Big Sur, I can no longer get my eGPU to work in Bootcamp. I tried reinstalling but none of the workarounds are successful. I’ve done the DDU and installed the drivers but I still get code 12 in device manager. EFI bootloader no longer works either.
Here’s the system I’m working with:
Late 2017 13” mbp 2 tb3 ports, no touchbar
Latest update of BIg Sur and Windows
Any help would be appreciated.
@macg, I did the update to Big Sur and it works exactly as before with EFI Bootloader, I'm sorry, but I can't tell you why the eGPU no longer works for you.
MacBook Pro (16-inch, 2019)
Intel Core i9 8 core
AMD Radeon Pro 5500M
eGPU: Aikidio node with AMD Radeon RX 5700 XT graphics card
@pierpaolo_mannini, When I try to hold option to bring up the boot menu with the bootloader usb drive and eGPU connected, it just gives me a black screen.
I meet no issue when i upgrade to big sur.
1.Make sure you can enter windows when you disconnect eGPU
2.Shutdown MacBook Pro
3.Connect eGPU and MacBook Pro should boot up automaticly. Immediately hold the option key to enter the system selection interface
4.Wait 5 seconds or so, disconnect eGPU
5.Select windows system, press enter, and connect eGPU after the windows logo appears before circle spinning
6.If you successfully enter the desktop, you would see that the yellow triangle in the device manager should be gone
7.It may be stuck or crashed after entering the system for the first time. Restart the computer once without eGPU, and use these magic tricks for the second restart.
8.If it is not successful, the timing of connecting eGPU may be wrong, try again
I've been trying as many workarounds as I can, but I can't seem to find one that sticks. I managed to get my egpu to work in bootcamp for about 3 seconds before it restarted Windows and caused my bootcamp to become stuck in a restart cycle. To get to that point, I used the automate-egpu.efi and did DDU and installed AMD drivers from bootcampdrivers.com. Anyone have any idea why it only worked for a few seconds before bricking my bootcamp into an endless restart cycle?
