So if you remove the HDD you believe is having the problem, you can't boot to Vista? Sounds like the boot files (or system files as MS refers to them) are on the bad HDD. Remove that HDD, boot from the Vista DVD and attempt to repair the bootloader. You'll need to go to command prompt, run diskpart, and make the partition active. Then exit diskpart, reboot, and boot from the DVD to recovery environment again. Run the following commands in a command prompt window.

bootrec /fixmbr
bootrec /rebuildbcd
bootrec /fixboot
