It had Windows installed and it was taking up 3 partitions or something so i destroyed its recovery drive and i probably need to start fresh with just Linux

Is there a way to just reset and do everything over like by repartitioning and installing something like Fedora or Ubuntu? I tried to jnstall PopOS and i think i settled on the ZorinOS or something but I can’t get Ethernet or my VPN working and I want to be able to download “app” “installers” like you do with PC or MacOS.
