Hi @ereilly57,
Generally Medion systems are provided with a recovery partition from which you an restore your system to factory settings, by pressing F11 during boot and following the instructions on screen.
If you somehow erased this partition, you can not restore this yourself, but you can download Windows 10 recovery media from the Microsoft site (Google for "Media Creation Tool", first link.).
