I want to reinstall Ubuntu, but I also want all information and settings to disappear. So everything looks like the first time I installed it. Is it possible to do so via Terminal? Or what are the steps I should follow?


You cannot perform a reinstallation of Ubuntu from an existing installation.

  1. Use Ubuntu live disk to boot up.
  2. Select Install Ubuntu on hard disk.
  3. Keep on following the wizard.
  4. Select the Erase Ubuntu and reinstall option (the third option in the image).

  • Does this set-up still work in 12.04 and do you need to have your home directory on a separate partition? Does this improve things? – Goddard Jan 4 '13 at 21:34
  • Yea, it works (I never needed to reinstall though so not tested by me), I never had /home in separate partion. Separate /home partition to separate your data. And improvement in what context (what improves what)? – Web-E Jan 5 '13 at 6:08
