This list specifies the order that the BIOS searches devices when trying to find an operating system to boot. 

To change the boot order select the device to be changed in the list on the right hand side, 

then click down arrows or use the keyboard PgUp/PgDn keys to change the boot order of the device. 

The boot devices can also be selected or de-selected from the list using the check boxes on the left hand side.

• Legacy Option ROMs need to be enabled for Legacy boot mode.
• Legacy boot mode is not allowed when Secure Boot is enabled.
• Clicking the “Load Defaults” button will change neither the Boot List option nor the Legacy Option ROMS setting, nor the Secure Boot setting — these three settings will remain unchanged.
