I have the followjng problem with ISO master software: I try to edit WIndows 7 ISO image
$ isomaster windows7.isoThe 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/ The UDF filesystem does not automatically mount properly in Ubuntu. See the question How to open UDF Volume for more info.
2I 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.
