You need to go into your laptop's EUFI settings and select the file to boot from. It's /Volumes/EFI/EFI/BOOT/CLOVERX64.efi. Then, select your EFI partition as the next boot partition. That way, your laptop knows to boot from EFI. Otherwise, it will look to boot from your system volume.
I don't see anywhere to modify UEFI settings in BIOS. Am I missing something?
