Boot Menu for OSMC?

I like OSMC as a media center, but I also like that I could add a desktop and Linux progs, and I want to use my HDD for either untouched ATV software OR perhaps hacked OSX on it.

What would be really useful would be a menu to select which to boot. Grub?

Can I get grub to boot OSMC to an LXDE desktop or do I need two USB sticks, one with untouched OSMC and one with LXDE installed?

And what entries would I need to then boot OSX/TVOS from HDD?

Anyone done it?

You could do this, but it’s outside the scope of this forum.
