System specs (model inc screen size, CPU, iGPU, dGPU, operating system)
imac late 2013 2,5 i5 quad core, intel iGPU, no dGPU
eGPU hardware razer core X, standard apple dongle to convert Tb3 to TB1, EVGA XC 2080 RTX gaming XC
Installation steps (what did you do to get it all going?)
had to struggle for weeks trying different variants, finally found that only sticking with windows 7/8.1 would work due to issues with windows 10 not activating iGPU even with OSX emulation causing error 12.
1. install refind, enable osx emulation
2. install windows 8.1
3. boot into safe mode, uninstall intel and nvidia drivers
4, plug in egpu and install latest drivers from nvidia website.
5, roll back intel driver if it tries to get installed otherwise it breaks the setup
