macos – How to install a new copy of Mojave on a Macbook Air?

When I do the Option + Command + R, I have several options. One of those options is to reinstall Mojave from an existing image. I do not want to use that image, rather, I want to install from a new image. For some reason I can not log into the laptop. Is there any way to load an image into a USB drive, place it in the USB port and install it using the Option + Command + R method?
