Public bug reported:
I'm using xenial image 20160323 on an XPS 13 2015 (9343). Booting 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.
