[Guide] How to keep Clover working when installing Windows and Linux

Intel internet access issue Mojave Clover hackintosh

Hi, I have a Clover hackintosh with Mojave, with Intel ethernet, Gigabyte motherboard.
Ethernet worked fine until today. The only thing I changed was that I disabled “wake for ethernet network access” and disabled wake on lan in bios.

Parallels boot camp partition booting broke after opencore update

My build has 2 separate NVME drives, one for OS X Monterey and another for Windows 10. I originally created the Windows disk using boot camp, then deleted boot camp and ran it with Parallels for the last 4 years.

I updated open core and I can still boot Windows 10 from the opencors picker menu no problem. Unfortunately I can no longer boot the same partition from Parallels. I now get this error:

Open Core or Bust

Ok. So I have ditched Clover for OpenCore and I'm excited from the positive responses and testimonials of the ease of use and stability of OpenCore.

So I have followed the Dortonia guide and created my bootable USB. I formatted the Hard Drive and slid the USB into the...
