As long as the correct kernel was saved as /boot/efi/boot/bootx64.efi, or the |
14 |
MoBo set up to boot from /boot/efi/boot/my_NVMe_kernel_x64.efi, you shouldn't |
15 |
have a problem booting up using the EFI boot stub. |

I have used GRUB2 to boot ISO images from USB drives and internal drives |
48 |
without problem, but Gummiboot is less fiddly to set up. With GRUB2 you need |
49 |
to pay attention in setting the path to the ISO correctly, or GRUB2 will error |
50 |
out of course. |
51 |
|
52 |
Unfortunately, you can't boot an ISO in true minimalist fashion just by |
53 |
pointing to it with the EFI boot stub (the ISO needs to be mounted via a |
54 |
loopback function). |
