So this is for booting on BIOS via El Torito (CD, DVD, BD)
and via MBR (USB stick, hard disk).

debian-7.5.0-amd64-netinst.iso of debian-cd got further applied
for UEFI:

  -eltorito-alt-boot \
  -e boot/grub/efi.img \
    -no-emul-boot \
    -isohybrid-gpt-basdat \
    -isohybrid-apm-hfsplus \

(Your -eltorito-alt-boot and debian-cd's -isohybrid-apm-hfsplus
 are actually surplus but do not harm either.)

boot/grub/efi.img is a FAT filesystem image. I am uncertain
under which cicumstances its content has to be adapted to
eventual changes in the boot software of the ISO.


Have a nice day :)
