PXE / Net boot / install is a thing but that’s not really meant for Linux noobs. Often times it’s something IT departments do to install the same OS image on multiple systems on the same network (not just Linux, Windows and others can do this too). I’ve never attempted to do that over the internet so can’t say much else about that process.

Being this is linux4noobs I suspect you’re just talking about one system being installed, a regular USB install would be far more feasible in your use case. You’re kind of going straight into hard mode attempting more advanced types of installs.
