This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

You just install something else ( like 10.04 ) in its place. Tell the installer to take over the whole disk and 12.04 will be gone.

@Nikki, then in that case, tell the installer to replace the existing Ubuntu installation. – psusi Jun 13 '12 at 15:58
will i get that option while installing ubuntu 10.04? – Nikki Jun 13 '12 at 15:59
@Nikki, you should. If not, then choose manual and point it to the same partitions the previous install used. – psusi Jun 13 '12 at 16:12

You don't need to uninstall if you just want to reinstall with something else.

If the machine has more than just the Ubuntu install on it - you'd want to pick the Something else.

Then you will get a window with the existing partitions.

Choose the linux one - change partition - then pick / as the mountpoint.

Save that and it will go back to the partition window - you carry on from there.

If you have a seperate home - do the same for /home as /.

I posted a very descriptive answer about removing Ubuntu here.

After that, install Ubuntu 10.04 the same way you installed Ubuntu 12.04.

Hope this helps.
