When I bought my computer it had Windows vista installed. I erased it and installed Windows XP. My sytem got crushed by a virus, hence I installed ubuntu 8.04. For possible fear of destroying my systems, I installed ubuntu 11.04 desktop edition alongside Ubuntu 8.04, but without defining the root file system. I am afraid I have erased OS's on my computer too many times.
May you please advise me on what to do to have the root file system defined.
