I don't really understand what isn't working. GRUB, the bootloader, probably has no problem with this.
Am I right in assuming the problem is with grub2-install(8), the program that is supposed to install GRUB? Or perhaps grubby(8). Oops, I answered in the wrong thread. It's grub all right, to be exact, /etc/grub.d/30_os-prober. If I make it non-executable (chmod -x), then all GRUB distros install cleanly.
That's run as part of installing grub. Or updating its menus. That finds what partitions have OSes and what OSes they have. That's not grub-the-bootloader actually running. There are surely ways of finding out what the os-prober is doing when it stops making progress. But you've moved past this point.
