Hello @jellan6789

Please enter some password (wrong password) 3 times, press [ENTER] and you should receive a new window stating system disabled and a code similar to this one - should be 8 characters long.

Please, take note of the system disabled/halted code (write it down).
Visit this web site >> https://bios-pw.org/
and enter the system disabled code
Click on "Get password" button there and you will receive your unlock code. Take note of the HP computers password and enter it in the system disabled screen , press [ENTER]. This will unlock your BIOS/reset security settings and PC should be able to start Windows (if WIndows can load).
Let me know how it goes. Provide your feedback.
