Linux kernel "No EFI Envirement Detected" message suppress in BIOS

hi...
i have my linux kernel built with EFI stub support.
and i setup to my OS to work on both BIOS and UEFI
and i my grub config like this,

set timeout=5
set default=0

# This menu entry will be automatically hidden by GRUB in BIOS mode.
# It will only be visible when booting via UEFI.
if [ "\$grub_platform" = "efi" ]; then
    menuentry "${OS_NAME} (UEFI Mode)" {
        linux /boot/bzImage quiet loglevel=3 console=tty0
    }
fi

# This menu entry will be automatically hidden by GRUB in UEFI mode.
# It will only be visible when booting via BIOS.
if [ "\$grub_platform" = "pc" ]; then
    menuentry "${OS_NAME} (BIOS Mode)" {
        linux /boot/bzImage quiet loglevel=3 console=tty0 noefi
    }
fi

# A verbose/debug entry that is always visible.
menuentry "${OS_NAME} (Verbose Debug Mode)" {
    linux /boot/bzImage console=tty0 console=ttyS0
}

but even i pass noefi in BIOS mode, i still see the message which says "No EFI Environment Detected"
how to remove/supress that warning?

thank uuu...

What does this have to do with Arch?

Is this an Arch question?
