KVM switch and its usage

If your Windows computer is not booting up and displays Secure Boot Violation – The system found unauthorized changes on the firmware, operating system, or UEFI drivers error message on the screen, then you can follow this tutorial to troubleshoot the problem. When you encounter this kind of problem on your computer, you will get the following error message on your screen:

“Secure Boot Violation The system found unauthorized changes on the firmware, operating system, or UEFI drivers. Press [OK] to run the next boot device or enter directly to BIOS Setup if there are no other boot devices installed. Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.”

This kind of error message pops up due to the Secure Boot that protects your computer from running any non-OEM signed boot software during startup. In other words, the Secure Boot firmware is the one that scans for non-signed boot software each time your computer boots up and if it detects anything strange, it will block the boot and will display the error message. To fix this error, there are two things you can try. You can try to disable the Secure Boot or try using a System Restore Point. For more detailed instructions, refer to each one of the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.

Option 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.
