hp pavillion laptop 15-p067ca model, purchased year ago, came with windows 8.1, was not updated to windows 10.
seems to have a bug: on start up it welcomes me as a user "vladimir" asks for password and then hangs up forever with the white screen and unresponsive.
Password I'm sure is right, because if I type different password, machine comes back with "Incorrect password" message.
What do you think is a problem and how to go back to factory settings?
I have not made a recovery disc.
Any comp supposedly have a recovery partition, and Recovery Manager but how can I do anything if Window does not come up?
