Well, I don't quite have the money for a new OS.
So, should I use Ubuntu?
Seeing as I wont be playing games on the computer at hand, would there be any other problems?
If it's a USB drive note that some computers/drives do not support booting from USB.
As far as I am aware, it's installed in the computer just as its current primary one.
I do know that it isn't USB, though.
