I opgraded my old pc that i used a long time ago and installed windows 7
and so i had 2 partitions and one works and the other won't i recovered it
i can use the files that are on it but i can't delete,format or do anything on it
when i restart my pc it gives me two opinions to boot Win7 or my other OS?
i don't have a other OS installed besides Win7.
