Ubuntu – Why ISO master (editor) does not read Windows images

isowindows 7

I have the followjng problem with ISO master software: I try to edit WIndows 7 ISO image

$ isomaster windows7.iso

The file does open, unfortunately all I get is README with message:

This disc contains a "UDF" file system and requires an operating
system that supports the ISO-13346 "UDF" file system specification.

isomaster comes form Ubuntu repository, I am using 12.04. The system has kernel support for UDF installed, I can mount above ISO (mount -o loop) and see its content read only. Any idea how to fix it? Using other than isomaster tool is also an option.

  • I used to use isomaster, but ran into this issue. Now I just add stuff to my iso's manually.

    mkdir new_iso
    mount -o loop iso_file.iso /mnt/
    sudo cp -Rva /mnt/* new_iso
    #Make your changes in the new_iso directory
    sudo umount /mnt
    cd new_iso
    sudo mkisofs -D -r -V "ISO NAME" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /home/USER/new.iso new_iso/
