Still not sure. It may have been that I did not check off secure boot, however, I could have sworn I did. I know I setup a TPN encryption password and verified this in my keychain. 

Anyway, I was finally able to install and currently installing Windows updates. The only thing I'm still wondering, is I had 3 versions of Windows in my ISO all from Sept 2022. And in your instructions, there were two versions from Jan 2023. 

But looks like Windows just finished updating, and my Windows 10 license key worked. So I think I'm ill set. 

Thank you for your help and also for making the guide. It was very helpful.
