FWIW on my "big box" the "sub-optimal boot entries" generated by Ubuntu 15.10 to select between it and updated CentOS and W7 and others works fine for me.

But I have no doubt that it could be improved.

It's easier to use any of the Fedora 24 net installs or server DVD, go
to Troubleshooting in the boot menu, then choose to rescue a fedora
system, and that will help assemble Fedora from fstab at /mnt/sysimage
and then just 'chroot /mnt/sysimage' rather than assembling it by
hand.

grub2-install
grub2-mkconfig -o /boot/grub2/grub.cfg
exit
reboot

Done.

But like I said previously, the automatically generated entries for
other distros suck. It really should find the grub.cfg for each distro
and use that directly rather than this cockamamie bullshit of creating
new and totally suboptimal boot entries for those distros.
