2. Secure Boot

This page explains how to disable Secure Boot.

  1. Find the Secure Boot setting in your BIOS menu. If possible, set it to Disabled. This option is usually in either the Security tab, the Boot tab, or the Authentication tab.

  2. Save changes and exit. The PC reboots.

  3. In some cases, you may need to change other settings in the firmware, such as enabling a Compatibility Support Module (CSM) to support legacy BIOS operating systems. To use a CSM, you may also need to reformat the hard drive using the Master Boot Record (MBR) format, and then reinstall Windows. For more info, see Windows Setup: Installing using the MBR or GPT partition style.
