The problem was sys-boot/grub-2.02_beta2-r9, which UEFI never ran. The fix was to get rid of grub altogether and instead use sys-boot/gummiboot. Not only was it fully functional, it was a welcome relief not to have to grapple with grub's baroque complexity and to be able to return to the simple booting I remember from years ago. I'd spent five long days wrestling with grub, going round in circles and getting nowhere, before I was pointed to gummiboot. Let's hope this helps someone else get a new computer booting. -- Rgds Peter
