If you are not going to install a non-beginner system like Arch or Gentoo then you should try a virtual machine first. Otherwise, it may come in handy if you want to choose a system with a desktop environment that suits you, because changing after installing a system for a novice user can be hard without avoiding problems.
In fact, on a virtual machine like Virtual Box you won't experience the problems you will encounter on real hardware (driver problem, etc.). It's better to test liveiso with Ventoy instead.
