@C0N0R,
Welcome to the HP Support Community!
I reviewed your post and I understand that you are getting keyboard error when you start the computer.
Don’t worry, I assure you I will try my best to get this sorted.
Have you tried pressing enter on that screen?
Meanwhile, I recommend you boot to BIOS by tapping the F10 key as soon as you power on the computer and restore the BIOS defaults and they check.
Follow the steps in the below video.

Let me know how it goes and you have a great day!
If you wish to show appreciation for my efforts, mark my post as Accept as Solution. Your feedback counts!
Cheers!
