As long as the correct kernel was saved as /boot/efi/boot/bootx64.efi, or the MoBo set up to boot from /boot/efi/boot/my_NVMe_kernel_x64.efi, you shouldn't have a problem booting up using the EFI boot stub. https://www.kernel.org/doc/Documentation/efi-stub.txt > > If > > > > > > you pointed grub2-install at the right place (the second command > > > > line > > > > > > at [1]), I believe you should have grubx64.efi there as well. > > > > > > Did you build GRUB with GRUB_PLATFORMS="efi-64"? > > > > Yes, as instructed in the wiki. > > > > > As you're using EFI, you may find life easier if you dispense with > > > > GRUB > > > > > and use Gummiboot.

I have used GRUB2 to boot ISO images from USB drives and internal drives without problem, but Gummiboot is less fiddly to set up. With GRUB2 you need to pay attention in setting the path to the ISO correctly, or GRUB2 will error out of course. Unfortunately, you can't boot an ISO in true minimalist fashion just by pointing to it with the EFI boot stub (the ISO needs to be mounted via a loopback function). -- Regards, Mick
