Make sure to perform a clean install by first erasing the whole physical drive as GUID partition and MacOS Extended (Journaled) while booted from the macOS USB installer:

Depending on the exact model of your Mac it may be possible to upgrade to a later version than macOS 10.13 if you have a 2012 or later model. If you provide us with the exact model of this Mac, then we can tell you the latest supported OS for this Mac. You can get the exact model by clicking the Apple menu and selecting "About This Mac".
