Sorry about that, I just took the time to read through the full thread and
I found your updated XML. I see you've already tried with all of the hyperv
lines removed.
Early in the thread you mentioned that "if I pull the GT 430 from the box
that I can see the boot on the GTX 760." If you pull the GT 430, do you
clear up the code 43 error? This could be worth trying, though I've never
tried running a guest on a headless machine personally (I've read others
have done it).
Have you tried swapping the slots that the 760 & 430 occupy?
Maybe there's something in the BIOS... What kind of motherboard do you
have?
