well, so much for the easy solution.
It sounds like you are trying to do a very difficult task in one big
step. That's never a good plan. The way I'd approach something like
1) basic macos install (yeah, sure...put it on 1/3rd of the disk)
2) Basic second OS install
3) Basic third OS install
4) Dual boot MacOS / [OS you are second-most familiar with on Mac
platform] (and again, leave some disk space free, so MAYBE you can go
right on to the next step without reloading completely from scratch)
5) Triple boot all three OSs
6) Start getting fancy by adding things like disk encryption.
Note the first three steps -- you MUST master the install of all three
OSs by themselves before tackling two at a time, and then three at a
time. Dual booting is tricky for people who understand all the OSs on
hw designed to use different OSs, coming in as a novice on any of the
OSs and working on a platform that assumed you would only run their OS
on it is going to be difficult.
Be very aware that, while I won't say your task is impossible, it may
not be something anyone has done before, and code may need to be written.
