Secure Boot Violation Error — How to Fix It?

When starting up your system, especially after a BIOS update or installing a new operating system, you may encounter a Secure Boot Violation error. Let’s explore what causes this error and how to resolve it.

What is Secure Boot?

Secure Boot is a security feature embedded in the BIOS/UEFI of modern computers. It prevents malicious software from running during system startup by verifying the digital signatures of drivers and the operating system. If the system detects unsigned components, it may block their execution, resulting in a Secure Boot Violation error.

Common Causes of the Secure Boot Violation Error

The Secure Boot Violation error can occur due to:

  • A BIOS or UEFI firmware update that changed the boot configuration.
  • Attempting to boot an operating system that doesn’t support Secure Boot (such as some versions of Linux).
  • Installing unsigned drivers or making changes to system settings.

Ways to Fix the Secure Boot Violation Error

There are several ways to resolve this issue. Try the following steps to fix the error.

1. Disable Secure Boot

The simplest way to address the error is to disable Secure Boot. To do this:

  1. Restart your computer and enter BIOS/UEFI. Usually, you can do this by pressing the Del, F2, F10, or Esc key during startup. The specific key may vary by manufacturer.
  2. Go to the Boot or Security section (the name may vary).
  3. Find the Secure Boot option and set it to Disabled.
  4. Save your changes and restart your computer.

After this, the computer should boot without any errors.

2. Enable CSM (Compatibility Support Module) Boot Mode

If you're using an older operating system or hardware that doesn’t support Secure Boot, enable CSM boot mode:

  1. Enter BIOS/UEFI as described above.
  2. In the Boot section, locate the CSM option and enable it.
  3. Save your changes and restart the computer.

3. Reset BIOS to Default Settings

If you recently updated the BIOS or changed its settings, you can try restoring the default settings:

  1. Enter BIOS/UEFI.
  2. Find the Restore Defaults or Load Default Settings option.
  3. Confirm the reset and save your changes.
  4. Restart your computer.

4. Update Secure Boot Keys

Sometimes, the issue arises because the required Secure Boot keys are missing. Updating the keys may help:

  1. Go to the Security section in BIOS/UEFI.
  2. Locate the Key Management or Secure Boot Keys option.
  3. Select Install Factory Default Keys.
  4. Save your changes and restart your computer.
