The Windows product key is in the BIOS.  You shouldn't need it to reinstall W10.


Here is a generic W10 Home key you can install for now when it asks, and then after W10 installs, you can change the generic key for the OEM key in your PC's BIOS.




Use the free tool that I zipped up and attached below, that will show you the product key and the version of W10 the key is good for.
