Why ISO master (editor) does not read Windows images

Question

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 wonder what you're trying to do with the contents a Windows 7 ISO image file since it's copyrighted material. If you use the udfinfo utility from the udftools package, you can verify that the UDF filesystem in the Windows 7/10 ISO image is read-only.

The UDF filesystem does not automatically mount properly in Ubuntu.  See the question How to open UDF Volume for more info.

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/
