    Hi samIOW.

    What kind of things has he tried? Have you booted to the Advance Startup options and tried a system restore and repair options?

    Before doing anything I would suggest you ensure his data is safely backed up off machine. You can use this procedure to create a bootable disc that allows you to use the standard windows interface to copy.

    Hi Ken,

    Thanks for your reply. As far as I know he has tried everything including repair although I am not sure if he has the restore option. I will ask him and get back to you.

    Thanks for the link too

    Cheers, Sam
