I should of known not to do this, but I created a separate partition and installed win 8.1. The main partition was running windows 7 with true crypt installed. When I boot up now, I get the option to choose between OS's, goes into win8.1 fine, but on win 7 partition, file are trying to be repaired. Within 8.1 I do not see the other win 7 partition. I used a boot magic disk and it shows the win 7 doesn't have a file structure. How Can I repair this?
