How to delete 12.10 Ubuntu completely [duplicate]

I need a simple guide to completely deleting Ubuntu 12.10 from my laptop in order to install the latest 20.04.2.0 LTS. I am not an IT fundi and I need a simple guide that I can follow.


First of take a backup of all your important files and documents.

Then make a bootable pendrive drive of ubuntu 20.04 and boot your laptop with this pendrive via boot menu.

While installation you will be given a three options . In your case they will be like following...

  • install Ubuntu 20.04 LTS along with ubuntu 12.04
  • erase the disk and install Ubuntu 20.04 LTS
  • something else.

in your case you have to choose second option.

-- If you want to keep ubuntu 12.04 than try something else but in this case you have to manage your partitions..

Hope it will help you..
