Look arch/x64/boot32.S and you will see Multiboot 1 compatible boot header.
My assumption is that "loader.bin" should be bootable under GRUB. You could
look into "grub-mkrescue", for example, to generate a bootable ISO image:

Please also note that most OSes have moved over to Multiboot 2, which is
not backward compatible with Multiboot 1. I think GRUB 2 supports the older
variant, but if you hit unexpected problems, make sure it's not related to
Multiboot 1/2 differences.
