Comment 12 for bug 1533258

What? That didn't make sense. Can you go into your bios and try to change the boot order there? It looks like it is buggy and refuses to accept the boot configuration and will only boot the hard drive like it is a removable media. You might try deleting the Boot directory on your EFI system partition and see if that helps ( but keep a copy of it somewhere else so you can put it back if the system becomes unbootable ). Otherwise, the only thing for it is to copy ubuntu/grubx64.efi to Boot/bootx64.efi and complain to the manufacturer about their broken firmware ( or better yet, return it for a refund and buy from someone who doesn't use broken firmware ). This is what boot-repair did when you used it before, and after updating grub, the copy is now out of date, hence the error.
