You may try Recuva.

Is the HD even detected in BIOS setup? If so run the HD maker's diagnostics to check its condition. This as well as other steps if necessary are found in Troubleshooting Windows 7 Failure to Start

If Windows can still see and read the drive you can try this http://www.sevenforums.com/tutorials/93347-copy-paste-windows-recovery-console.html. Sometimes a live Linux distro can see and read data on the drive.
