Most brobably the product key is hidden in BIOS. Consult computer vendor support for help.

Hi Sam,
As mentioned by Milos, in most of cases OEM License is tied to the hardware and only could be used to activate certain edition/version of Windows. Since they are completely hosted by OEM Manufacturers, Microsoft has no information about these key status or the process/limitation of licenses activation. Regarding to OEM license question, Id suggest that we contact with OEM Manufacturer. There you can get more effective suggestion by other experts who familiar with design of OEM edition Windows. Your understanding is highly appreciated.
Since third party clone software frequently cause system corruption and its not fixable, we only recommend one way for system installation on new hard disk: performing a clean install on your hard drive.
