PUJING,

Return the BIOS to UEFI Boot

You can resolve this issue by returning the system to the UEFI boot mode.

  1. From a power off state, power on the system and Press F2 boot into BIOS setup menu.
  2. Choice "Boot sequence" and change the option from "Legacy" to "UEFI" then press "Apply" on the right-down corner.
  3. Choice "Advance Boot options" and disable "Enable Legacy Operation ROMs" then press "Apply" on the right-down corner.
  4. Choice "Secure Boot" -> "Secure Boot Enable" and change the option from "Disabled to Enabled", then press "Apply" on the right-down corner.
    1. Press "Exit" on the right-down corner and wait the system reboot.
