The BIOS was recovered after a failed BIOS update caused by a power outage. Windows boots normally with Secure Boot disabled, but enabling Secure Boot prevents the system from booting.

Hi @novacop296,

Welcome to the HP Support Community.
 

Thank you for posting your query. I'll be glad to help you.
 

I understand that the BIOS recovery completed successfully after the BIOS update was interrupted by a power outage. However, the notebook only boots when Secure Boot is disabled, and enabling Secure Boot prevents Windows from starting.
 

This behavior can occur if the BIOS recovery reset certain UEFI or Secure Boot settings, or if the Windows boot configuration no longer matches the Secure Boot requirements.
 

To help narrow this down, could you please provide the following details?

  • What is the exact HP computer model or Product Number?
  • What is the current BIOS version installed?
  • Do you receive any error message when Secure Boot is enabled, or does the system simply fail to boot?
  • Is the drive configured in UEFI mode with a GPT partition, or was Windows originally installed using Legacy/MBR?
     

In the meantime, I'd recommend the following checks:

  1. Enter the BIOS Setup and verify that the Boot Mode is set to UEFI (not Legacy).
  2. Load the BIOS Setup Defaults, save the changes, and restart the computer.
  3. If the system still only boots with Secure Boot disabled, run HP PC Hardware Diagnostics (press F2 at startup) and perform the Storage Test to verify that the SSD is healthy.
  4. If a newer BIOS version is available for your model on support.hp.com/us-en, update the BIOS again using the HP-recommended method to ensure the recovery completed correctly.

Once you've shared the HP model, BIOS version, and the exact behavior or error when Secure Boot is enabled, we'll be able to determine whether this is related to the BIOS recovery, the Windows boot configuration, or the SSD, and guide you with the appropriate next steps.

I'm an HP Employee.
