There is no need to use RUFUS. It is incredibly easy to create the Windows 10 installation USB flash drive with no extra software at all (except that Windows 7 needs extra software to mount the ISO file if you are creating the flash drive in Windows 7). RUFUS will just give you more confusing options.
In addition to @Superfly's suggestion to use ShowKey to check the firmware for a product key, I would also suggest you use the Check Key function of the same program and test your Windows 10 Pro product key to make sure it is correct and legitimate.
