Hi Kenneth,
I am Dave, an Independent Advisor, I will help you with this.
If you click Start, OneKey Recovery will restore your PC to its factory default, if you choose the top option on that screen, you will loose all your personal files and your PC will be like it was when you first bought your PC.
If you do not have a restore point you created, then you may not be able to save your personal data on that PC.
What exactly happened before that screen started to show up, did you get a large Windows update, or did your system crash?
When you start your PC, do you see the Lenovo logo screen, and if so, do you then see the spinning dots indicating Windows 10 is attempting to load, before the OneKey screen shows up?
