Upgraded Windows 10 to Windows 11 on MSI Modern 14 earlier this year via Update assistant. I saw the latest Windows 11 22H2 update and put the MSI modern 14 to upgrade via Windows 11 Installation Assistant downloaded from Microsoft site:https://www.microsoft.com/software-download/windows11During the installation maybe about 80% I forgot about it and shut down the computer. Did something like this before and there was not problem. So I didn't think about it as I was tired and went to sleep.Opend up the laptop next morning and it shows a message saying "SECURE BOOT VIOLATION" and after i pressed

secure boot violation

My laptop had a critical update which was downloaded automatically.

I asked it to restart after installing the update.

After the "MSI" welcome screen a message came up saying"

Secure Boot Violation

Invalid signature detected. Check Secure Boot Policy in Setup

It is the first time I received this message and can't make out what i should be doing.

Any help would be appreciated.

 

Secure Boot Violation error

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you receive a warning regarding Secure Boot Violation when booting the PC. For further clarity on the issue, please respond to the questions below:

1. 
   
   1. What is the make and model of the PC?
      
   2. Which build version of Windows 10 are you using currently?
      

Meanwhile, I would suggest you to follow the steps mentioned below and see if that helps.



Method 1:



Try loading the BIOS to default settings and see if the issue persist. You may want to get in touch with the manufacturer of the PC for further assistance with resetting BIOS.



In addition, you can check if any update for BIOS is available and try updating the BIOS by contacting the manufacturer.



Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems
resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.



Method 2:



Disable Driver Signature Enforcement, and see if you are able to boot to Windows normally.

1. Now press Windows +
   S key together to open Search.
   
2. Now type CMD and select Run as administrator.
   
3. Accept the UAC prompts.
   
4. Type in the following command and hit Enter:
   
   bcdedit.exe /set nointegritychecks on
   
5. Restart the PC
   

Let us know how it goes.

Windows 8 Secure Boot Feature: Not So Secure?

• Linux
• Linux
• Linux
• Linux
• Oh and OSX

Here is a statement from a Kernal Developer at Red Hat:

I'm not sure this exploits the legacy BIOS but rather it exploits the legacy boot method on MBR drives, injecting a signed key before the OS boots, which you are correct in that it has nothing to do with Windows 8. And the simplest fix would just be to require boot drives use GPT when Secure Boot is enabled in UEFI.
