Fix 3: Change Secure Boot Mode / Modify BIOS Secure Boot Configuration
In case the error of Secure Boot Violation – Invalid Signature Detected still occurs despite the simple fixes, it is possible to modify the Secure Boot configuration on a more profound level to fix the corrupted boot files or signature conflicts. Hence, take the entire step-by-step procedure below:-
1. Make sure the Secure Boot is Disabled, as done in the first solution. Save and exit BIOS (F10 on most devices). Your computer will now attempt to boot normally into Windows.
2. Then, open File Explorer.
3. Go to this way:-
C:\Windows\Boot\EFI
Look for the file “SecureBootRecovery.efi”.
Note: In case your device lacks the file SecureBootRecovery.efi, you can omit the rest of the steps and go directly to the re-enabling of Secure Boot.
4. Insert the USB flash drive. Right-click on it and choose “Format”.
2. Format it as “FAT32”.
3. After formatting, open the USB drive. Make a new folder called EFI. Open the “EFI” folder and create another folder named “BOOT”.
4. After, return to this way.
C:\Windows\Boot\EFI
Copy the file “SecureBootRecovery.efi”. Paste it inside the “BOOT” folder on your USB drive.
5. Click the file with the right-click button and select Rename. At this point, change its name to: “bootx64.efi”. This enables your system to accept it as a legitimate boot file.
6. Restart your computer. Hold Esc and press the Power button. In the boot options list, select “Use a Device”. Then, choose your USB drive.
Automatically, your system will boot up via the USB and reboot the required secure boot files. Wait until the system shows a recovery message and then wait until the automatic restart.
7. At this point, we are going to re-enable Secure Boot in BIOS, which we turned off previously in the first solution.
