Hi @1234142,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The "Boot Device Not Found" error on your HP All-in-One 24 indicates that your system is unable to detect a bootable operating system on your hard disk. Here's how to troubleshoot and resolve the issue.

Check Boot Order in BIOS

1. Restart your computer and press the F10 key repeatedly during startup to enter the BIOS setup.
2. Navigate to the Boot Options or Boot Order menu.
3. Ensure that the primary hard drive (usually named something like "HDD" or "SSD") is set as the first boot device.
4. Save and exit the BIOS.

Perform a Hard Drive Test

1. Enter the BIOS again (press F10 during startup).
2. Navigate to the Diagnostics or Tools section.
3. Run the Hard Drive Test to check for any hardware issues.
   • If the test fails, your hard drive may need to be replaced.
   • If the test passes, proceed to the next steps.

Check Physical Connections

1. Turn off your PC and disconnect the power supply.
2. Open the back panel of the All-in-One (if you're comfortable doing so).
3. Ensure the hard drive is securely connected to the motherboard.
4. Reassemble the system and try booting again.

Recover or Reinstall the Operating System

1. Create a Bootable USB Drive:
   • Use another computer to download the Windows OS from the Microsoft website and create a bootable USB drive.
2. Boot from USB:
   • Insert the USB drive into your All-in-One.
   • Restart the PC and press Esc or F9 repeatedly to open the boot menu.
   • Select the USB drive and follow the prompts to reinstall Windows.

I hope this helps.

Take care and have a good day.
