Hi @Kirex,

Welcome to HP Support Community.

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

The error code 0xc000000f on an HP laptop typically indicates a problem with the Boot Configuration Data (BCD) file, which is essential for the operating system to start up properly. Here are some steps you can try to resolve this issue.

Automatic Repair

1. Restart your laptop and let it try to boot.
2. When the error appears, it should prompt you to "Repair your computer." If it doesn't, you might need to force it to boot into the recovery environment:
   • For Windows 10/11: Power off the laptop while it's booting up a few times (power off as it's loading the Windows logo). This should trigger the recovery environment.
   • For Windows 8.1/8: There might be a specific key combination like Shift + F8 or Shift + F11 during boot to enter the recovery environment.
3. In the recovery environment, choose "Troubleshoot" > "Advanced options" > "Startup Repair." Let it run and see if it fixes the issue.

Using Command Prompt

1. Follow the steps to enter the recovery environment as mentioned above.
2. Instead of Startup Repair, choose "Command Prompt."
3. In the Command Prompt, type the following commands one by one, pressing Enter after each.

bootrec /scanos 

bootrec /rebuildbcd

• If prompted to add the installation to the boot list, type "Y" for Yes.
• If it finds Windows installations, you can also try.

bootrec /fixmbr 

bootrec /fixboot

After running these commands, restart your laptop and see if it boots properly.

 

Rebuild BCD Manually

1. Boot into the Command Prompt as described above.
2. Type the following commands one by one, pressing Enter after each.

diskpart 

list disk 

Select disk X 

list volume

• Note down the volume letter of the Windows installation (it's usually "C:").

1. Assuming "C:" is the Windows volume, continue with.

exit 

cd /d C:\EFI\Microsoft\Boot\ 

attrib BCD -s -h -r 

ren BCD BCD.old 

bootrec /rebuildbcd

1. When asked to add the installation to the boot list, type "Y" for Yes.
2. Restart your laptop.

System Restore

1. If you have a restore point created, you can try to restore your system to a previous working state.
2. In the recovery environment, choose "System Restore" and follow the on-screen instructions.

Check Hardware

Sometimes, this error can also be caused by faulty hardware. You might want to check your hard drive or SSD for any issues. If you have a spare hard drive, you can also try installing Windows on that to see if the error persists.

Notes

• Always back up important data if possible before attempting these fixes.
• If none of these methods work, you might need to consider reinstalling Windows, especially if the issue seems to be with the operating system files.

I hope this helps.

Take care and have a good day.
