I also recommend rEFInd for the bootloader if you don’t want to set anything up (and risk messing up). You don’t need to configure your boot entries, it scans for boot options and shows them with a graphical interface, so your Linux and Windows should just show up.
It’s not like Bethesda called their games “Fantasy” - “Civilization” is such a generic name that I respect putting the author’s name before it to avoid any confusion.
