Hey Waldo,
Welcome to PCHF. We have a wonderful team of techs here, and I feel certain that we will be able to help you figure this out.
My first question is actually a concern that you are not showing the files that you currently have on your J drive. Before attempting any kind of move you should make sure that the drive is fully available to you. If you do not need the files that we over there, I would suggest that you reformat that drive, and make sure that all partitions are available.
My second question is why you don't simply move the files over after installing Windows onto your J drive? That would be the simplest way to handle this. It would also give you the best chance for a clean and successful move.
Looking forward to your reply,
TTFN
