Set Boot Priority
Boot Mode Allows you to select Legacy or UEFI boot mode.
NOTE: Legacy boot mode if selected, enables booting to
devices that support Legacy BIOS. UEFI boot mode if
selected, enables UEFI drivers.
CAUTION: Changing boot modes require that
your boot storage device be partitioned to
match the boot mode compatibility. Changing
boot modes could result in an incompatible boot
storage device, which may prevent the original
OS boot. Restoring the boot mode may resolve
an incompatible boot storage device failure and
recover the original OS boot.
Usb Boot Support Allows you to enable or disable booting from USB mass
storage devices such as hard drive, optical drive, USB flash
drives, and so on.
