I have an old computer that I had upgraded to 7 ultimate a while back. It is not my main comp, and due to incompatibility issues running old games, (which is what this will be used for), I want to switch back to xp. Too many issues even trying to run in comparability mode, frustrating. I know when I upgraded to 7 it kept all of my photos, etc saved in a separate partition/folder called OLD. Will this occur again, or will I lose everything. The other ? is I will be taking that HD out of an old dell with an intel CPU and putting into a different machine with an AMD CPU. I have the driver cd for that motherboard so am guessing just a matter of booting from DVD drive to download. I am sure I have done this in the past, but was a long time ago so want to do it right. Thanks
