I have a windows xp and when turning on my computer is keeps asking for a system disk and to press enter. my question is 1, I have this Dantz Retrospect Express backup 7.0 for optical drive storage. I am wondering if this is the disk they asking for if not what does this disk go to. 2 where can iIget the correct disk, 3. will this reset my computer to factory reset. I need to get some file off before I do a fatory reset.
