It depend on how you created your recovery disk and how you restore. But frankly, I would advise against this primarily because you have a notebook and notebooks tend to be very proprietary - that is, you must ensure you have all the necessary Dell drivers before you start.
If the upgrade to W10 went well without any problems, I don't see why you want to do a clean install of W10. I would just suggest you create a back up image of your current W10, and keep it safe in case you have problems later.
