But this post didn’t suggest Docker, it suggested a VM. This would be a totally sensible thing to do as you can just recreate it if you mess it up. Virtualbox works fine on Windows and Linux. Install it and spin up a distro.

Mate, the suggestions you have been given for VMs and docker are to help you recover easily should you mess up. If you are going to moan about that…maybe just install bare metal and get on with it yourself?
