There is a point in getting help to perform an professional installation of Windows, just like the ULTIMATE Windows 10 installation-guide from [SPAM REMOVED BY ADMIN] that makes sure you do not forget any steps or perform the steps in the wrong way, just like you have done...

Then you should RESET your laptop, by entering Start-button, settings, Update & security, then go to: Recovery..
