After installing a clean windows 8 onto a 120gb ssd everything worked fine. Installed new 1tb and 500gb HD as slaves. The 500gb used to be the primary. Restarted PC now it says no operating system found and disconnect drives with no OS. After removing and swapping everything around it still says no OS. Please help!

With SATA you can hot swap, so boot from your SSD with both HDDs disconnected from the SATA ports and re-connect before opening disk manager to initialize them and format the 500 Gb one to remove any residual unwanted boot info...
