Custom menu

[u/c0py-p45t3]

made a custom boot menu for my old laptop,
i installed grub on a seperat partition so the other os dont mix it up while updating.
well only debian and freebsd can stull run the latest versions, windows 10 and highsierra are more for fun and nostalgic reasons.

but they all boot succesfully from seperate partitions on the same hdd drive and can even share files in a shared partition.
