If you're using Windows XP - Professional then use the Security tab to add yourself as the Owner to the files and folders.
If you're using Windows XP - Home Edition use this article to add a Security tab and then add yourself as the Owner of the files and folders.

As for fixing the whole two Operating Systems thing, I suggest you remove all partitions and then format the Hard Drive (after recovering any data you can), then make a new partition and install a fresh copy of Windows onto it.
Edit: You can do this using the Windows XP Installation disc; boot from the CD to reach this menu.

This I do not understand. Could you explain a bit clearer please?
