Hello friends, if today when you turn on your laptop, the time is wrong or it doesn't let you boot the operating system and you constantly see messages like these:
- ERROR: Verification failed: (0x1A) Security Violation
- Secure Boot Violation. Invalid Signature Detected. Check Secure Boot Policy in Setup
