According to your profile, you have a Nvidia GTX 1070 graphics card. Nvidia makes their own drivers for use in macOS and publishes them on their website (also known as Nvidia WebDriver). You can find more information in
this post. Note that Nvidia has not updated the WebDrivers to work on Mojave as of this time (26 Nov 2018), so you use macOS 10.13 High Sierra for now.
Im going back to the basics Conath! Removed Graphics card/switched to the applicable motherboard settings (exactly the same as yours). Followed your vid guide for the USB boot stick, even downloaded the same clover version as in the video. Used this guides provided config_sample.plist (assuming its setup for your hardware/same as mine). Same kexts folder...
The interesting thing is my USB won't show in the boot loader when I power it on after BIOS adjustments. Only shows when BIOS is set to Legacy+UEFI... when I tried installing with that setting it gets stuck at the apple logo and doesn't load. Let me know what you think...?
Additional Qs:
DO I need to reset CMOS/NVRAM?
Could the clover boot loader you used in video not be compatible with my version High Sierra (10.13.6)?
Im a noobie, so apologies in advance. Thanks for your help again!
