Ubuntu – How to reinstall ubuntu 14.04

14.04reinstall

I recently installed ubuntu 14.04 , but when i installed it the laptop was not connected to internet.
But now the bluetooth is not working and laptop only gets connected to wifi for 20 minutes then it never again connects.
I figured out that if i reinstall ubuntu while conected to internet it will install proper drivers.
So how do i completely remove ubuntu from laptop and then reinstal it?
Plz give me acurate procedure.
