Hi GerardoMora,
Welcome to the HP Community, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I saw your post regarding the fact you seem to be stuck at the “Press the ESC key” screen. Have you tried pressing F8 as the system boots up to try and enter safe mode? One possible solution that was suggested by CherylG in this thread was removing and reinserting the hard drive. How long have you had the notebook for? If you have had it for less then a year then I don't try that option as opening the notebook would void your warranty. If you have had it for longer then a year reply back with your product number and I can provide a guide to show how to remove the hard drive.
Thank you,
