I wrote my previous thread without engaging brain first! I have now found various helpful threads on the subject. I would still like to read the online course referred to by John in his thread.
In the topic Creating a dual-boot setup... I could not connect to the online course via the link. I got to Today on CNET! - with no indication of where to go or what to do next.
I also could not get a sensible result from the PM me in John Wilkinson's welcome message. I presume addressing this problem directly to John would have been the correct way to do things?
I am really interested in a dual-boot setup and would appreciate any help in realising that. I want to dual-boot XP Pro and Vista Ultimate mostly because I am not convinced that Vista is markedly better than XP (I only have both because my son works for Microsoft with all the attendant benefits!).
