Since you got Windows 10 OEM (attached to your motherboard), all you need is to install Windows on your new hard drive. Just make sure you're installing the same version that you have before, I mean, if you had Windows 10 Home, install Windows 10 Home, if you had Windows 10 Pro, install Windows 10 Pro.
All you need is install Windows using Media Creation Tool (you can get it at
https://www.microsoft.com/en-us/software-downlo...) and then during Windows installation, when it asks for the key, just skip and select the option
