My operating system, Windows XP broke. It said to use the restore CD. It

couldn't repair itself. I accidently put 2 operating systems on the same

computer. It put 2 Windows side by side. I can't get to my old files, data or

music. I know they are there because they are taking up 22 GB on my hard

drive. The hard drive did not partition. Does anyone know what to do??

Thanks in advance.
