Try installing refind - it is pretty good at detecting multiple OSes.

That said, if you have a shared boot partition between installations,
then you're going to have a much harder time detecting things, since
each OS will run update-grub, and clobber the other's grub.cfg entries.

You might be better off writing your own grub.cfg file or customizing
scripts in /etc/kernel to handle regenerating grub.cfg when there are
kernel updates.
