    if it's booting under Legacy, your OS installation was done under Legacy, the only way to use UEFI is to re-install the OS with UEFI set on BIOS.

    have you tried with an USB flash drive?

    the OS must be x64 and the USB flash drive must have GPT partition scheme and be FAT32 formatted.

     

    i also suggest you to enable F12 boot menu on BIOS:

    press F2 at boot to enter BIOS, browse to Boot menu and enable F12 key, press F10 to save and exit.

    plug your USB flash drive and at boot press F12 to enable boot list and choose the USB flash drive brand and model.
