Making IMG

.img generation is intended to use from Linux. Contribution is welcome to support docs of other OS.

  dd if=/dev/zero of=boot.img bs=1M count=512 status=progress
  mkfs.fat -F 32 boot.img
  sudo mount boot.img mnt --mkdir
  mkdir -p mnt/EFI/BOOT

  # Change uefi-video.efi to the desired file.
  # It's in releases if you download, and it's in target/x86_64-unknown-uefi/release if you build your own.
  cp uefi-video.efi mnt/EFI/BOOT/bootx64.efi
  sudo umount mnt
  rmdir mnt

  # use boot.img as you want
