Not really a solution to what you need, but you should consider distros other than manjaro, it does some shady stuff, has ddos'ed the AUR multiple times (even though the AUR is "unsupported") and let the security certificates for their site expire (their solution: to turn back your clock to update the system). You should try endeavour instead.
Very interesting and also such a shame. Manjaro seems to have most support and definitely looks and feel the greatest that I've tried, all well being newbish friendly

Gahhh so virtualization is the best route huh? What about lxd/lxc, KVM, or other containers, possibly gnome boxes?
virt-manager uses QEMU/KVM by default. Some distros do work in containers too.
Xen turn your PC into a hypervisor. Where you can switch your OS without much hassle.
Making each OS boot on bare metal will make you cry if you want to be able to boot several different OSes.
That is very surprising to hear. In my mind, if I keep the distros minimal, it seems itd be a simple enough task on the surface. But I guess there's more that goes into it
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
