I'm not sure if it is useful, but with the advent of UEFI only machines,
we've run into a similar problem w/ out custom CentOS 7 USB installation
keys.
Basically, we create a gpt device w/ a single FAT16 partition (this
would be your /boot partition for a full installation) containing an
EFI/BOOT/ directory with the syslinux-efi files and a SYSLINUX/
directory with the syslinux-bios files.
Would further info on this be helpful?
