How to partition

Reference to: Partitioning during installation [added by moderator]

I want a dual partition. I want to migrate from Windows 10 to another platform.

I’m not understanding the “create root (/), swap, home (/home), and ESP/EFI (50 MB)” commands. Is this done during installation? Is it at the command prompt?

I’m very wary of creating changes until I know for sure that nothing is going to go wrong. And I need simple answers. I’m not totally unfamiliar with computers, but form your answer(s) as if you’re talking to someone with limited experience.

Thanks.
