Is there a way to load my current Zorin 16.3 Core system into VirtualBox?

I'd like to find a way to load my current system into VBox so I can try the upgrade to version 17 there before upgrading my real system. Has anyone found a way to do that?

Thanks!!!

See if this helps:

Please note the reference to lilo.conf in the last post. As far as I am aware lilo or rather LILO (LInux LOader) was the boot loader in early Linux, and because of the potential risks of using it is what deterred me from trying GNU/Linux in the early days.

Thanks, I will take a look at that.
