About DBAN (from their site)

Darik's Boot and Nuke ("DBAN" ) is a self-contained boot disk that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.

It looks like it works well. All you have to do is reinstall or perform a complete restore.

To boot to the installation DVD, in BIOS select the DVD as the first boot device. Think...how could the system boot to the drive? It's been wiped. The drive needs to be formatted using the Windows installation disk before it becomes bootable.

The OP wiped the hard disk with an excellent application that properly erases everything, i.e., it can't be recovered. How could replacing a cable help? The only solutions are to either reinstall everything or restore from a complete backup.
