I have had good service for 7 years using Vista on my Dell Desktop and I regularly do disk partition and system back ups using EaseUS Todo onto my external hard driive. Can anyone please advise what I could do if the worst happened and the Dell computer disk failed? Would i be able to restore the external saved files on a later operating system, say Win 7, or would I need to try and get another PC with Vista installed? There does not seem much point in doing back-ups if they are not going to work. Help would be much appreciated.
