Thanks! I have followed your guide several times over. It is a bit confusing for someone with little to no knowledge of BIOS interactions etc. I am learning as I go here. The last time I built a PC from the ground up was in High School and that was 20 years ago. I am sure I'll figure it out and I am MORE than sure that I am making this harder on myself than it needs to be. I wished I had someone around that knows this so I could watch one from beginning to end. I learn better with my hands. Anyway, thank you for all of your help, I really appreciate it! I'l let you know how it goes...

I am sure you will succeed in the end . Just take it easy and do not knot or panic! Do what I write line by line. Forget about the rest. Dedicate all your time to make Sierra run on your system. Afterwards perform a Windows UEFI install on a separate disk and everything will be fine and work as supposed. You will see..

Thank you! Do you think I should just completely wipe the drives and start fresh from BIOS configuration step 1? Basically, remove Win 10 and the Sierra install that didn't take.

Yes indeed, just start with my guide (BIOS settings, USB installation medium, post-installation procedure). Forget about NVMe and xcpm. That might be too complicated for now. You can try it later on, once you are more experienced. Just perform the basic Sierra installation.

Once you have a running sierra system, you perform an UEFI-Windows installation on a separate disk. All information required for this last step can be easily found in google.

By doing so you will learn a lot and one day you will teach us how to do things better

Right on! I am hoping this will work for me. I have just wiped the SSD(s) and went back through the BIOS setup line by line, step by step. I booted with the USB in and immediately went to Clover installer. I choose to run installer from external (usb stick) and am currently in Disk Utility prepping the drive for OS X. I'm pulling the trigger on the install now...

Here's the best I could do for a screenshot of the frozen drives.

Bu why you are now back to the secure erase story? This is certainly not part of my guide...

You have to format the disk on a MAC with Mac OS Extended and a GUID partition table.

No no I'm not, I just wanted to show you what I was seeing earlier. macOS is currently installing. It's after this part when I start running into trouble. Someone else posted earlier and said that after I install Sierra, reboot from USB again and then use Clover to boot from Sierra SSD. Once in Sierra, install Clover to the SSD. Is that right?

Yes that's right. Once clover and sierra are installed on your system disk, you will be able to boot from there. You just have to finally define in the Mobo BIOS the system disk to be your startup disk.

Yes that's right.

OK cool. Thank you so much!! This has been the longest 4 min waiting for Sierra to finish installing. I just realized the system has frozen. Dang it!! Starting over again...

Apart from correct BIOS settings and clover, ensure that you have the proper config.plist and files in the /kexts/10.12/ and /drivers64UEFI/ directories, both on your USB disk and system disk! The freezing of your system is suspicious!
