Hi @Batu_ZCAN 

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

Thanks for explaining the issue so clearly. A BIOS update followed by a “boot device not found” error and brief flashes of a blue screen often points to a misconfigured boot order, a corrupted boot sector, or a disrupted link between the BIOS and the hard drive. 

Let’s walk through a structured recovery approach:

Reset BIOS to Default Settings:

• Restart the computer and press F10 as it powers on to enter BIOS Setup.
• Once in BIOS, go to the Main tab.
• Select Restore Defaults or Load Setup Defaults.
• Save changes and exit the BIOS.

Reseat the Hard Drive:

• Turn off your notebook and disconnect the power cord and battery (if removable).
• Open the access panel and reseat the hard drive, ensuring it is firmly connected.
• Reassemble the notebook and reconnect the power.

Check BIOS Boot Order:

• Access BIOS again by pressing F10 during startup.
• Navigate to the Boot tab.
• Ensure your hard drive is set as the primary boot device in the boot order.

Perform a Hard Reset:

• Disconnect all external devices (e.g., USB storage, printers).
• Turn off the computer and unplug the AC adapter.
• Remove the battery (if applicable).
• Press and hold the power button for at least 15 seconds.
• Reinstall the battery and reconnect the AC adapter, then turn the computer back on.

Run HP PC Hardware Diagnostics:

• Upon startup, press ESC and then F2 to access diagnostics.
• Run the system and component tests to check the functionality of your hard drive.

Check for BIOS/UEFI Updates:

• Visit the HP support website to ensure you have the latest BIOS/UEFI firmware.

Use HP Support Assistant:

• Ensure drivers and software are up-to-date using HP Support Assistant.

 

Additional Considerations:

• Verify Cables and Connections: Ensure all cables and connections inside the computer are secure and not damaged.
• Consider Using Safe Mode: Booting into safe mode can sometimes bypass software-related conflicts that affect startup.

Let me know how far you get with these steps. If the issue persists, we can explore deeper board-level diagnostics or alternate recovery paths.
