FS1 is ESP of the disk in the system (not used here). FS2 is the contents of a partition of the El-Torito image on the CD.

It was done by my scripts to hack PLD Rescue CD into an EFI-bootable image. The relevant commands called by the script: # Building the HDD image # efiboot/ contains /EFI/BOOT/BOOTX64.EFI which is the EFI shell # syslinux is installed for BIOS boot, not relevant here dd if=/dev/zero of=efiboot.img bs=$cylinder count=${cyls} lodev=$(losetup --partscan --find --show efiboot.img) sfdisk "$lodev" <<EOF ,,e,* ; ; ; EOF dd if=/usr/share/syslinux/mbr.bin of="$lodev" mkdosfs -F 16 -n "EFIBOOT" "${lodev}p1" mount "${lodev}p1" "$mntdir" cp -aL efiboot/* "$mntdir/" cp efiboot/startup.nsh "$mntdir/EFI/BOOT" umount $mntdir losetup -d $lodev # building of the ISO image mkisofs -v -J -R -D -A "${VERSION}_H" -V "${VERSION}_H" -no-emul-boot -boot-info-table \ -boot-load-size 4 -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.catalog \ -eltorito-alt-boot -hard-disk-boot -e boot/efiboot.img \ -A "PLD Linux RescueCD $VER (EFI+legacy)" \ -p "http://rescuecd.pld-linux.org/" \ -log-file $LOG -o "image.iso" new The 'new' directory containst the boot/isolinux/isolinux.bin and boot/efiboot.img files. boot/efibootimage is the image created with the previous set of commands. > Not without special arrangements. grub-mkrescue is using xorriso which > builds hybrid ISO image containing extra partition table(s) which > results in GRUB being able to access El-Torito boot image as normal > HDD partition. I think I will need to take a look at this xorriso then… I hoped I can do with the standard mkisofs.
