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.

I installed ubuntu using a bootable pendrive. How can reinstall it properly to make all things work – Manish Sakpal Nov 28 '15 at 15:32

I installed Ubuntu from a bootable USB stick as well, and just today I reinstalled it the exact same way I originally installed it. Have you tried that so far? – Sam Estep Nov 28 '15 at 15:39

Ok it means you overwrited it. Does overwriting deletes all previous contents? – Manish Sakpal Nov 28 '15 at 16:19

Yes; I keep everything important backed up on the cloud, so that's not a problem for me. If you need to keep your existing files, you'll need to either copy them off your drive and then copy then back after reinstalling, or use a different option. – Sam Estep Nov 28 '15 at 16:21

To completely remove and reinstall Ubuntu
- Boot from Ubuntu installation media.
- Select Try Ubuntu without installing.
When the desktop appears - open GParted.
Format the Ubuntu partition with ext4.
Close GParted, click on Install Ubuntu.
When asked - choose Something else.
Select the partition formatted before.
Then select / (root) as the mount point.
Start installing Ubuntu to this partition.

@Manishsakpal : The best and recommended way while installing is to have the laptop connected to the internet using an ethernet cable. :) – cl-netbox Nov 28 '15 at 15:58

@Manishsakpal : The advantage is a stable connection and in case the WiFi adapter needs special drivers, they can be installed properly. :) – cl-netbox Nov 28 '15 at 16:19

@cl-netbox, +1 Very thank you for this I am trying this. I want to know that I
dev/nvme0n1p3 ext4 203.17GiBis this need to be formatted as per you 3 option. And I need to select Format to ext4. Please help me. – L.K. Sep 29 '16 at 07:39 -
@L.K. : In case /dev/nvme0n1p3 is the partition you have Ubuntu installed on, yes - select format to ext4 ... although in GParted the partition should show as /dev/sda1 for example and nvme0n1p3 as label (name). – cl-netbox Sep 29 '16 at 08:39
