corrupt

So I was attempting to encrypt my (Windows 7) system drive with Truecrypt and it stopped at around 15% and said that there was a segment error and that it could not proceed until it was fixed. So, I restarted the computer and ran HDD Regenerator which subsequently fixed the bad sectors on the drive, but now my system cannot boot.

So, I run a number of recovery disks to no avail (Windows repair is unable to fix) and the drive won't mount on a linux version run from a CD because the drive is encrypted. So I tried mounting the drive using Truecrypt under the Linux distribution on the disk and selected "Mount partition using system encryption without pre-boot authentication" so I can decrypt, but I get an error message about it only being possible once the entire system is encrypted.

How do I get out of this mess? I need to be able to back up the data that's on that partially encrypted drive so I can reinstall my operating system.
