Newer nForce chipsets got lots of troubles with the SATA & IDE controllers because driver support is very poor.
Are you installing from/to IDE or SATA? Assuming its SATA you can get around most problems using SATA AHCI mode if available. If you are using IDE or AHCI is not supported by your specific nForce SATA Controller you may need to add a modded driver to the installation to get it working.
