Thanks. I've replied to ubuntuforums. Concerning the first attempt,instead,I have created the folder iso_unpacked_and_modified and inside of it I have placed the folder isolinux with the file isolinux.bin. This is what happened :
script2.sh orig_iso=debian-live-11.5.0-amd64-xfce.iso new_files=debian-live-11.5.0-amd64-xfce new_iso=debian-live-11.5.0-amd64-modified-xfce.iso mbr_template=isohdpfx.bin # Extract MBR template file to disk dd if="$orig_iso" bs=1 count=432 of="$mbr_template" xorriso \ -outdev debian-live-11.5.0-amd64-xfce.iso \ -volid d-live \ -padding 0 \ -map /home/ziomario/Scrivania/PassT-Cubic/ISO/iso_unpacked_and_modified / \ -chmod 0755 / -- \ -boot_image isolinux dir=/isolinux \ -boot_image isolinux system_area=/home/ziomario/Scrivania/PassT-Cubic/ISO/isohdpfx.bin \ -boot_image any next \ -boot_image any efi_path=boot/grub/efi.img \ -boot_image isolinux partition_entry=gpt_basdat # ./script2.sh 432+0 record dentro 432+0 record fuori 432 bytes copied, 0.000496522 s, 870 kB/s xorriso 1.5.4 : RockRidge filesystem manipulator, libburnia project.
