How do I disable secure boot?

To disable secure boot, enter the BIOS on start-up by tapping F2. In the BIOS, find the secure boot option under the advance menu and set it to disabled. Then press F10 to save and exit. Please note: If you enter the BIOS in any way other than by tapping F2 on start-up, the setting might not save correctly, so make sure to enter the BIOS only by tapping F2 on start-up.
