Windows 10: Windows 10 install

Quick question,

I have a laptop that had an HDD failure. It had Win7 Pro on it. I did not have a recovery disk nor the OEM Win7 Pro install disk so I did a clean install of Win10 Pro and now get the unlicensed Windows OS message. Since Win10 is offered as a free migrate can I transfer the Win7 Pro product key to Win10 or do I need to find the Win7 Pro disk and run install then migrate? Thank you.

Installing Windows 10 on New PC?

I'm going to be building a new PC on Christmas and want to install Windows 10 on it. I have Windows 10 on my current PC, which I installed upgrading from 8.1 with the files on a USB. How do I go about installing a clean copy of Windows 10 on this new PC? I think I recall something about installing it once makes Microsoft recognize your hardware, but since this will be a PC I'm not sure what steps I need to take. Do I need to go 8.1 -> 10 or is there a method of going directly to 10?
