Turn ON Secure Boot to prevent malicious programs from loading as your computer starts up. It is also needed to upgrade to Windows 11.

What is Secure Boot?

Secure Boot is a security feature that ensures your computer boots up using only software that is trusted by its manufacturer. This blocks malicious programs from running on your computer at system startup.

How to access Secure Boot

  1. Click the Start , then go to Settings > Update & Security > Recovery.
  2. Under Advanced startup, choose Restart Now.
  3. On the next screen that appears, select Troubleshoot > Advanced options > UEFI Firmware Settings > Restart to make changes.
  4. Switch the PC boot mode from Legacy BIOS (or CSM Mode in some computers) to UEFI/BIOS (Unified Extensible Firmware Interface).

    In some PCs, there are options to enable both UEFI and Legacy/CSM. If so, you will need to choose for UEFI to be the first or only option.

    We recommend checking your PC manufacturer’s support information on their website if you are hesitant to make any changes to enable UEFI/BIOS.
