Welcome to HP Forums @Mikekirk,

Thanks for the post. 

I understand that your computer is not booting and you are getting a message that says boot device not found. 

Not to worry, I will be glad to help. 

Have you tried any troubleshooting steps on your own?

Boot device not found comes up when the HDD on your computer has gone bad or is not getting detected. 

Request you boot the computer to BIOS by tapping F10 repeatedly on startup. 

Restore BIOS to defaults, save and exit. 

Run a system test on your computer. 

For other troubleshooting steps, please refer to this HP Article and let me know how it goes. 

Keep me posted.
