Ok so I had some files on this hard drive now which didnt have an os and was part of another os until that crashed. So I booted to linux live and it showed the files i had on here so I installed linux thinking I could still be able to access them. When it said there was data and asked if i wanted to mount it i said no because i still needed those files so it created another primary partition with no filesystem so i uninstalled linux and installed windows 7 and in the disk management it shows up as a basic primary partition for 4.96 gb which is about how much data is on there but there is no filesystem and the only thing i can do with it is delete it. I have tried testdisk and i cannot seem to access the partition. i tried using linux live cd to recover them and it dosnt work on that either. someone please help me recover these. i have a paper i need for school to graduate on there.
