Secure boot issue invalid signature

Title: OMEN 30L GT13-1000a - Secure Boot Violation "Invalid Signature Detected" with BIOS F.24

I have an HP OMEN 30L GT13-1000a (Product Number 399T3AA#ABA) currently running BIOS F.24.

Secure Boot worked previously on this system. However, when I now enable Secure Boot in BIOS, the system immediately stops before Windows loads and displays:

"Secure Boot Violation"
"Invalid signature detected. Check Secure Boot Policy in Setup."

Current configuration:

• Windows 11 Home

• BIOS Mode: UEFI

• TPM 2.0 enabled, activated, and functioning

• GPT system disk

• AMD Ryzen 5 5600G

• HP OEM RTX 3060

Troubleshooting already completed:

• Verified UEFI mode

• Verified GPT disk

• Verified TPM health and provisioning

• Verified Platform Key is enrolled

• Verified PK, KEK, db, and dbx Secure Boot databases are present

• Rebuilt EFI boot files using BCDBOOT

• Verified Windows Boot Manager path

• Loaded BIOS Setup Defaults

• Disabled USB Boot and Network Boot for testing

• Confirmed no custom bootloader or Linux installation

Windows reports Secure Boot State = Off because the system cannot successfully boot with Secure Boot enabled.

This is also preventing applications that require Secure Boot from running. Call of Duty reports:

"Secure Boot Requisite not met: Secure Boot not Enabled."

One additional concern is that HP's support page for ROM Family SSID 8876 appears to list BIOS F.13, while my system reports BIOS F.24 dated October 2025.

Has anyone seen this issue before or know of a Secure Boot recovery procedure, BIOS rollback option, or firmware fix for BIOS F.24?

Thank you.

Hi @Havoc721,

Welcome to the HP Support Community.
 

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

Thank you for providing such a detailed breakdown of the issue and the troubleshooting you've already completed. It certainly helps narrow things down.

Based on the product number 399T3AA#ABA that you shared, I'm currently only able to find BIOS F.13 listed for this platform, which was released in 2025. At this time, I'm unable to locate any HP-published BIOS release newer than F.13 for this specific model, which makes the reported F.24 (October 2025) version particularly interesting and something I'd like to investigate further.

To help us verify the system configuration and available firmware information, could you please send the following via private message?

• Serial Number 
• Confirmation of the full product number (399T3AA#ABA) 
• A screenshot or photo showing the BIOS version reported as F.24
• If available, the BIOS Information page from System Information (msinfo32)
   

Given that:

• Secure Boot previously worked, 
• The PK, KEK, db, and dbx databases are present. 
• Windows Boot Manager has been rebuilt, 
• The system is configured for UEFI/GPT, 

The behaviour you're describing is not what we would normally expect. If you've already tried any additional Secure Boot recovery steps beyond those listed above, please let us know what you've attempted so we can avoid having you repeat the same work.

Once we have the serial number and confirmation of the BIOS version being reported, we'll take a closer look at the platform details and see if there is any additional guidance, recovery procedure, or firmware information available for this specific configuration.

Looking forward to your reply.

I hope this helps.

Take care and have an amazing day!

Thank you I am sending you a PM!

Hi @Havoc721,

Thank you for the clarification. For the OMEN 30L Desktop PC GT13-1000a (207P7AV), when I check the information available for this platform, the latest BIOS version I am currently able to find is F.13. Because of that, seeing the system report F.24 does not look quite right, and I'd like to verify exactly what the PC is reporting before we proceed further.
 

Could you please share a photo of the BIOS Version/Date screen?
 

You can locate it using either of these methods:

Method 1: From Windows

1. Press Windows + R.
2. Type msinfo32 and press Enter.
3. In the System Information window, look for BIOS Version/Date.
4. Take a photo or screenshot of that section and share it with us.
    

Method 2: From BIOS Setup

1. Restart the PC.
2. Repeatedly tap F10 when the HP logo appears.
3. On the Main or System Information page, locate the BIOS version.
4. Take a photo and share it with us.

Once we can see the BIOS version being reported by the system, we can compare it with the BIOS releases available for the platform and determine the best next steps.
 

Looking forward to the image so we can check this further and help better.

Hi @Havoc721,

Based on the information provided, I can see that the system is currently running BIOS version F.24 dated 10/14/2025. At the moment, it appears that the BIOS version installed on the PC does not match what is currently being displayed on the HP support website for this model, and because of that, we will need to investigate this further before providing any additional guidance.
 

I will be forwarding these details to the relevant team for further review. Once they have had an opportunity to investigate the BIOS version discrepancy and determine whether there are any known issues or additional steps required, we will provide an update.
 

Please note that this investigation may take some time, and we appreciate your patience while the team reviews the information.
 

Thank you again for providing the screenshot. We will keep you updated as soon as we receive additional information from the relevant team.
