On systems that boot from EFI by default, qemu cannot read the image #56

So I've spent a couple days struggling with this, but I finally found an answer that helped.

tl;dr If you're developing in an OS that has been booted on an EFI system, grub-mkrescue assumes you want your image to have the EFI protections as well. In that case, you'll see a message about failing to boot from CDROM, specifically code 0009. In that case, you need to install grub-pc-bin and update your Makefile so the grub-mkrescue line looks like:

    grub-mkrescue /usr/lib/grub/i386-pc -o build/os.iso build/isofiles

Cheers!
