Thanks so much for your reply and your help. I installed using legacy boot and it worked fine -- in fact, I'm responding from "untrusted firefox" right now! I don't know if qubes comes up in the grub menu yet. I just got this installed, and ran it from the BIOS boot sequence Legacy-USB option, and I'm off for some errands myself.
However, in lieu of killing myself with UEFI, since this works, I'll stick with it and am a happy camper. Maybe in the next week I'll play around more with UEFI, but I'm going to have to learn a bit more about it, I think. Anyway, you made my weekend!
