I think the only way you could achieve that goal would be a clean install of win 10 as if you have a partition on drive set aside by OEM for factory restore, then it won't ever get written over by windows 10. Doing a clean install will remove it completely.

Download the Windows 10 media creation tool and use it to make a win 10 installer on USB

change boot order in BIOS so USB is first, hdd second
boot from installer
follow this guide: http://www.tenforums.com/tutorials/1950-windows-10-clean-install.html

when you reach the screen asking for licence, click "I don't have a key" and win 10 will continue to install and reactivate once finished

On the screen where you choose where to install win 10, if it gives you an error about GPT drives, delete all the partitions on the hdd and press next. If it still gives error, cancel out of the installer and restart PC and start installer again, it will accept next on that screen this time (some PC just need a restart here)

Fresh install also likely to remove chance of corruption since all the drivers will be new.

Exactly what Colif said. During the clean install choose to delete all of your existing partitions and you will be fine.
