Boot Device Not Found - Hard Disk (3F0)

HP Pavilion All-in-One - 24-x035qe
Microsoft Windows 10 (64-bit)

 

I just passed by my computer and noticed it had a black screen with the blue box stating:

Boot Device Not Found

Please install an operating system on your hard drive

Hard Disk (3F0)

 

I searched and found that I should turn it off and press Esc and then F2 to run System Diagnostics. Now I am simply frozen on a new black/blue screen. I pressed F2 but nothing is happening. 

 

I don’t know how or when any of this occurred. The last time I used my computer was probably Friday evening (2/8) and I just noticed this tonight (2/10). My computer is just days over one year old. Yes, the warranty expired approximately 25 days ago. 

 

Customer service is closed of course. They will be open when I am at work all day tomorrow and no time to deal with this mess. 

 

What is happening and how do I fix it???

Now it moved to a third screen but nothing I press on the keyboard does anything. It’s just stuck here
