Followed the tutorial to create a bootable usb drive from ubuntu 18.04 iso - it doesn't boot. Tried several other ways/utilities, still getting:

Failed to open \EFI\BOOT\NULL - Not Found
Failed to load image \EFI\BOOT\NULL: Not Found
start_image() returned Not Found

Obtained from this Korean blog:

Inside the USB drive go to \EFI\BOOT\, copy grubx64.efi and rename the copy to NULL (not NULL.efi but simply NULL)

It worked for me.

  • Thanks, will try next time; for now, I've set it up on my MacBook through Parallels – johngo Jun 29 '20 at 1:03
  • Tried it on LG gram 14 inch 2018 edition. It worked! – closure Aug 18 '20 at 21:40
