Hi All Thanks for all the replies. I did the checks on the hard drive and couldn't find anything wrong. It was frustrating and then by chance I found the usb pen drive was the element that had caused the problem. I bought a new stick, loaded up a new Ubuntu and reinstalled and everything is fine. I'm not sure if I could have repaired the install but there were so many problems I thought it easier to reinstall. Thanks for all the help.
