With a Win 10 system, if the system is capable, you can reset your install to a new hard drive and have a Factory install. I may keep some of your settings if you choose but it will basically be as it came from the factory. By capable, I mean one set up to allow for the OEM utilities in the recovery partition being able to be copied over to the Recovery drive along with the Win 10 image.
If you want something to recover to your current install you will need an image. I use the one in Windows but it is limited in some aspect. Others suggest using a third party imaging software.
I don't think the Dell backup software is available on the Win 10 systems..
