I recently installed elementary os thinking it was a relatively good operating system... However I've been mainly disappointed as I use public hotspots quite a lot and I can't actually connect to them on elementary so here's my question how do I install Ubuntu on Elementary OS. I also have a few limitations: - No CD-Drivd - No USB Stick
Is this possible or do I need to buy a USB?
Just to clarify I'm installing Ubuntu over a Linux OS not a Windows OS
