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.
