   But it was a M$-driven PLOT - mostly to hurt Linux.

   With GRUB you only need to load ONE thing, GRUB, at
   boot. Then IT takes care of all the alternatives. It
   will work just fine from a non-UEFI medium.

   Now if, for some reason, you don't WANT to use anything
   like GRUB then, yea, the data in the UEFI can theoretically
   boot multiple systems (until M$ decides it shouldn't by
   adding a few 'poison' bytes somewhere (they'll call it
   a 'security enhancement')).
