File dates indicate W10 installed 2018. Pulled fresh from shelf Apr 2025.

Hi @Ray94,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your laptop!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Verify BIOS Version

Make sure the latest BIOS version is compatible with both Windows 10 and Windows 11. Visit the HP support website to confirm the correct BIOS version for your model.

Reset BIOS Settings

Reset the BIOS settings to default. This can often resolve boot issues. To reset BIOS:

• Turn off the laptop.
• Power it on and immediately start pressing the Esc key repeatedly until the Startup Menu appears.
• Press F10 to enter BIOS Setup.
• In BIOS Setup, look for a "Restore Defaults" or "Load Setup Defaults" option.
• Apply the default settings and save the changes.

Check Boot Order

Ensure that the boot order prioritizes the correct hard drive or partition:

• Enter BIOS Setup using the steps above.
• Navigate to the Boot Options menu.
• Make sure the system boots from the correct drive where Windows is installed.

Repair Windows Bootloader

Use the Windows 11 DVD to repair the bootloader:

• Insert the Windows 11 installation DVD and boot from it.
• Choose "Repair your computer" from the Windows Setup screen.
• Select Troubleshoot -> Advanced options -> Command Prompt.
• Run the following commands:bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd

Check for Drive Issues

Ensure the hard drive doesn’t have any issues:

• Use tools like HP System Diagnostics to perform hard drive tests.
• You can access the HP System Diagnostics tool by pressing F2 during startup.

I hope this helps.
