So mini-update, I think you are right…it looks like it added both entrees to my boot menu here:

But it appears that even when selecting the new ‘antergos-grub’ it does the same thing (both Antergos and Win10 fails).
Any last “hell mary” suggestions? Nothing left to lose…if we can’t get it, I’ll probably start over tomorrow with a fresh install of both OS’'s unfortunately.
@manuel - Let me know if I missed one of your suggestions. I think you just wanted the output of the Boot Options Menu, and make sure the results of each grub menu entree?
Thanks again guys, I appreciate everyone’s time and help so far!
