Grub, as far as I know, deals with assembly for each target.

You need a 32bit toolchain with binaries since you want to run with 32bit arch. There are options where you can run multi-arch but you need to know how that works. Grub can be built for both targeted systems if you have the proper toolchain to do so. Has anyone had issues building grub target for x86_64 with a 32bit system? If I recall properly, grub takes care of this on its own. Grub doesn't loop mount iso images. Nor does the kernel. It's filesystem matter and grub won't deal with that. Grub is a boot manager, not a filesytem manger. It doesn't work that way. If you have a module that you can load, then it'd work. Someone correct me if I'm wrong on that part. Boot managers don't usually deal with filesystem mounting.
