Hello,
I have a Razer Blade Model Blade Pro 17 (Early 2021) - RZ09-0368.
I’m experiencing the Secure Boot Violation ("Invalid signature detected") issue. I already followed the official Razer recovery guide using the USB drive and the securebootrecovery.efi procedure. The recovery works correctly, and Windows boots normally afterwards.
Unfortunately, the fix is only temporary. After about one day (or after the laptop has been powered off for some time), the exact same Secure Boot Violation returns and I have to repeat the whole recovery process again.
Things I have already tried:
- Followed the official Razer Secure Boot recovery guide
- Enabled and disabled Secure Boot
- Saved BIOS settings correctly
- Repeated the complete recovery procedure multiple times
Has anyone found a permanent solution?
Has Razer identified whether this is related to BIOS firmware, Secure Boot keys, the CMOS battery, or another firmware issue?
Further information: Microsoft Windows 11 Home; BIOS-Version/-Date Razer 1.00, 17.12.2020
Any help would be greatly appreciated.
Thank you.
Greetings from good old Germany!
