Hi,

yes, you can install both on the same machine. No, you can not switch between both by a shortcut. You need to reboot, to start the other operating system.

While it‘s possible to run one operating system as guest inside of the another operating system, this approach has got several disadvantages.

Don‘t believe all the unqualifiziert nonsense claimed about Linux. Linux is stable. All operating systems have got pitfalls. Android has not much in common with Linux and iOS/iPad OS have not much in common with FreeBSD.

What operating system to use depends much on the domain.

One domain that is important to me is real-time audio. The infrastructure related to audio and real-time of iOS/iPad OS as well as Linux is quite good, while FreeBSD is not that good in this domain. Android is completely inappropriate for real-time audio.

IOW it even doesn‘t matter much, if an operating system is based on another operating system, since they can differ a lot.

Actually I‘m using iOS/iPad OS as well as Linux most of the times and rarely FreeBSD or Windows, but I never used Android for the mentioned reasons. I run Windows only as a guest inside of another operating system. In some cases this approach has got more advantages, than disadvantages.

Summarized, what operating system to use and if it makes sense to run it as a guest inside of another operating system depends on several factors. What are your domains?

If a dual- or multi-boot makes sense depends, too.

Only one claim is nearly universal, if a user is unsatisfied by one operating system, it usually doesn‘t solve anything  to migrate to another operating system, if the migration is based on promise of salvation. A thoughtless migration is much likely just a jump out of the frying pan into the fire.

If you want to test operating systems, a starting point to do this is using persistent live media. For example, copy several Linux live ISO to a Ventoy USB-stick and make them persistent and get NomadBSD. Testing an operating system as guest in a virtual machine suffers from the limits of the virtualization, especially when using VirtualBox, let alone that anything hardware related depends on the host‘s drivers, hence you can‘t experience hardware support of the guest.
