I have a problem with my Next book 8 Windows10 tablet. When I booted up somehow it went to a set up page with various options (continue, use a device, use another operating system, troubleshoot and turn off your PC) I have gone through the options which give me other options like reset this PC, advanced options, system restore, start up repair and so on. I have followed the instructions but nothing will take me back to Windows 10. Would be grateful for any suggestions
