Thanks wizards! Changing the boot order did the trick. If I seem a little dense, it's because working at the BIOS/UEFI level is new to me. I'm a retired professor who used to employ wizards to do this kind of thing for me.
Maybe one of you experts could explain something I still don't understand: Why did "Ubuntu" come up in the list of devices? Did Protectli labeled the NVME with "Ubuntu"? If so, how did the label survive my deletion of the GPT?
Thanks again for the education! -- F
