As read on the Fedora Wiki, this command could be used to create a bootable ISO for BIOS and UEFI:
$ mkisofs -U -A "MyRockstor" -V "MyRockstor Disc 1" \
-volset "MyRockstor" -J -joliet-long -r -v -T -x ./lost+found \
-o ~/MyRockstor/iso/MyRockstor-disc1-dualboot.iso \
-b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 \
-boot-info-table -eltorito-alt-boot -e images/efiboot.img -no-emul-boot .
