How to roll back Ubuntu to a previous version?
I have a macbook pro and i have successfully installed windows 7 via bootcamp and then installed ubuntu 12.10 along side windows 7. It works fine... but for my school project i need to use ubuntu 12.04 - i know i should have known this from the start, would have made things easier :-/
Now my question is how to uninstall 12.10 and then reinstall 12.04? i think it wouldnt be a problem to install 12.04 but the question is more how to uninstall 12.10?
thank you.
