If you're using GPT partitions, install the GPT MBR onto the drive you want to install the bootloader on (in this case /dev/sda):
  dd bs=440 count=1 conv=notrunc if=/usr/share/syslinux/gptmbr.bin of=/dev/sda
Or if you're using DOS partitions, install the DOS MBR instead:
  dd bs=440 count=1 conv=notrunc if=/usr/share/syslinux/mbr.bin of=/dev/vda

extlinux --install /mnt

mkdir -p /mnt/syslinux
cp /usr/share/syslinux/efi64/* /mnt/syslinux/
