Hi @Ian19642,
Welcome to the HP Support Community.
I'd like to help!
If the Hard Disk Error 3F0 boot device not found is displayed on a black screen, use the following procedures to try to resolve the error.

Turn off the computer and wait five seconds.
Press the power button to start the computer and repeatedly press the f10 key to enter the BIOS setup menu.
On the BIOS Setup screen, press f9 to select and load the BIOS Setup Default settings.
Press f10 to Save and Exit.
Use the arrow keys to select Yes, and then press Enter when asked Exit Saving Changes.
Follow the prompts to restart your computer.
