# 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.
