Booting (to + grub) with the image on a USB stick is enough to make my previously + installed system unbootable! 1. Have the system in EFI mode and an installed Ubuntu system. I have Secure Boot on too. Make sure the installation boots properly. 2. Burn image to USB drive. I used dd, but doubt that matters. 3. Insert USB drive. 4. Reboot. 5. See the grub menu. 6. Don't choose anything. Turn the system off. 7. Take the USB stick out. 8. Turn it back on. 9. See "No bootable devices fdund." Obviously at "9" it should instead boot. You can repair the system by entering setup (F2) and re-adding the boot entry. Settings -> General -> Boot Sequence -> Add Boot Option. Click the "…" next to File Name and pick EFI/ubuntu/shimx64.efi. Then exit setup and it should reboot and work again.
