Hi,
I have Dell Inspiron 700 series, with windows 8.1 . I wanted to upgrade to windows 10, but didn't have the app, so I used the Dell "refresh PC" (or something like that) that is supposed to restore the OS without deleting my documents, pictures etc. After reboot, I see this message "windows could not complete the installation", I reboot again and get the same message. What should I do?
