          You should make sure the USB disk is bootable and
          has syslinux installed.

          $ sudo apt install mbr syslinux
          $ sudo install-mbr /dev/CHANGEME
          $ sudo syslinux -i /dev/CHANGEME1
          $ sudo fdisk       /dev/CHANGEME
          [Here, make sure partition 1 is marked bootable.]

          for UEFI these steps need to be done

          $ sudo apt install syslinux-efi
          $ cp /usr/lib/syslinux/modules/efi64/* {{ usbdrive_path }}/EFI/boot/

          This will NOT be done automatically.
