isohybrid is for "El Torito no-emulation" boot images (such as those
using isolinux.bin) and you are using "El Torito hard disk emulation".
Unfortunately, syslinux.efi v.6.03 is not capable of booting optical
media in UEFI mode. Please read the wiki (and the "FAQ" link posted in
the isohybrid wiki page).
