Hello Razer Support,
My Razer Blade 15 Base (2021) shows a "Secure Boot Violation - Invalid signature detected. Check Secure Boot Policy in Setup" error every time Secure Boot is enabled in the BIOS. The laptop boots into Windows 11 normally only when Secure Boot is disabled.
This is NOT a hardware fault - the laptop works perfectly with Secure Boot off.
Device details:
- Model: RZ09-0369 (Product No. RZ09-0369AG22)
- Serial No.: I will provide via private message
- OS: Windows 11
Troubleshooting already done:
- Rebuilt the Windows bootloader on the EFI partition using bcdboot (C:\Windows /s S: /f UEFI) - it completed successfully, but the violation still appears with Secure Boot enabled.
- The BIOS Secure Boot menu only shows System Mode (Deployed), Vendor Keys (Active) and an Enable/Disable toggle. There is no Key Management, no Secure Boot Mode, and no option to restore or reset the Secure Boot keys.
- Windows is genuine, BitLocker is off, and there is no dual-boot or third-party bootloader.
This appears to be the known firmware issue where the Secure Boot key database (PK/KEK/db) no longer trusts the Microsoft-signed Windows Boot Manager, and it cannot be reset from the BIOS menu.
Could a Razer representative please provide the Secure Boot recovery package for my model (RZ09-0369), or advise the correct procedure? I understand other users with the same issue received the recovery file via private message. I have an empty USB drive ready.
Thank you for your help.
