Answer 1

Hi ,

Search for msinfo32.exe in the search bar, take a screenshot, and post it here so we can see the correct laptop model or desktop configuration.

The keys are probably loaded incorrectly; we would have to reset the keys.

Thanks

Don't worry, your GPT drive setup and UEFI settings are perfectly fine! This error simply means Secure Boot is actively blocking a startup component (like an old GPU firmware, third-party hardware driver, or a slightly corrupted boot file) because its digital signature isn’t matching your motherboard's current key database.

To clear the violation, try this quick sequence in your BIOS:

Go back to your Secure Boot menu and look for an option to Clear Secure Boot Keys or Reset to Manufacturing Defaults. Clear them out first, save, and reboot back into the BIOS.

Next, select Install Default Keys (or Restore Factory Keys) to cleanly reload the updated Microsoft and hardware vendor database.

If it still throws a fit when you enable Secure Boot, look for an option in your BIOS called Key Management and change the boot priority type from Custom back to Standard.

If none of that clears the block, a background hardware component (frequently an older graphics card) might need a quick UEFI firmware update from the manufacturer to play nice with modern Secure Boot standards!
