Hi @Missy2214 

Welcome to the HP Support Community! We're here to help you get back up and running.

That blue box message—“Boot Device Not Found”—is deeply unsettling, especially after you've run all the diagnostics and followed every prompt. It usually means the system can't detect a valid drive to boot from, but there are a few things we can still try to bring it back to life. 

Let’s walk through a few targeted steps:

 

1. Check BIOS for drive detection

• Power off the PC completely.
• Power it on and immediately tap Esc repeatedly until the Startup Menu appears.
• Press F10 to enter BIOS Setup.
• In BIOS, go to Storage or System Information and check if the hard drive or SSD is listed.
  • If it’s not listed, the drive may be disconnected or failed.
  • If it is listed, continue to the next step.

 

2. Reset BIOS to defaults

• While still in BIOS, press F9 to load setup defaults.
• Confirm and press F10 to save and exit.
• Let the system try to boot again.

 

3. Run UEFI diagnostics again

• Power on and tap Esc, then press F2 for System Diagnostics.
• Run the Storage Test and Memory Test.
  • If the storage test fails, the drive may need to be replaced.
  • If it passes, the boot files may be corrupted.

 

4. Try booting from recovery media

If the drive is detected but won’t boot:

• Use another Windows PC to create a recovery USB:
  • Download the Windows Media Creation Tool and follow the steps to create a bootable USB.
• Insert it into the affected PC and boot from USB:
  • Tap Esc, then F9 to choose boot device.
  • Select the USB drive.
• Choose Repair your computer > Troubleshoot > Startup Repair.

 

5. Check Secure Boot and Legacy Boot settings

• In BIOS, under Boot Options, try toggling:
  • Secure Boot: Disable it.
  • Legacy Boot: Enable it.
• Save changes and try booting again.

If the drive isn’t showing up at all, it may have failed physically. But if it’s detected and diagnostics pass, recovery options are still on the table. 

Let me know what you see in BIOS or diagnostics, and I’ll guide you further.
