I can't explain, but I got it to boot off the old EFI partition on the SSD the OS is installed on. Still can't get the thumbdrive to work, but at least I can get in now. It gives me more options to play around with things with a working build.

CSM was on before, which was a surprise to me. I could swear I turned it off. That said, no change in the symptoms, regular mode or safe mode. I have iMac 14,2 set as the device ID at the moment.

This is the Graphics Injector menu, correct? It's 67FF and cannot be modified. This the right place to look? InjectATI is unchecked. I searched the config.plist and it doesn't get set in there.

I tried with DisplayPort, no change. I tried that with agdpmod=pikera too, same result. I updated Lilu and WhateverGreen on my thumbdrive EFI, no change.

Neither! My only available port is a DVI port.

I put ssdt-EC.aml in the patches directory of my thumbdrive. Still seeing the same behavior. I tried with the bootarg Gigamaxx mentioned above, as well as safe mode. Still have the same behavior. I see the apple logo (or logs, depending on whether I'm using the verbose flag) for a couple of...

No, I don't have ssdt-EC.aml. I've tried playing around with different SMBIOS settings, no love.

Nope, same results with that. Both in safe mode and without.

Yes, this was the problem. I switched from legacy because I couldn't get the motherboard to detect the USB key. I changed a bio setting to force it and it would take it after that and now I can boot into the installer. In the BIOS there is a line for "Legacy USB Support". I had it as...

Sorry, I thought I had everything and I missed legacy (Yup, it's legacy boot). Thanks, I will check that out. I assume these have to be manually patched into the EFI partition on the thumb drive? The last time I did this, Unibeast did all the magics.

Yup, that got it going. Thanks!

Using: Asrock z97 Pro4 with an i5 4690K, 8GB Ram, Nvida video. System is rock solid and stable when I boot from my installer drive. It picks up the high sierra partition on my SSD and all is right with the world. That said, I have not been able to get the bootloader on my EFI partition. If I...

El-Cap Asrock Z97 PRO4 - GT740 won't boot without NV_DISABLE=1 Solved with shame. There are 10.11.4 drivers. My google foo just sucks. Works like a charm now and did not require any action further than driver install.
