As far as I know the CD-ROM file system is read only. The work around
is: read the files into a suitable directory ("cp -rp /mnt/winiso/*
/new/directory/somewhere/" [ -rp to copy recursively and preserve
permissions]), edit at will. Then create a new ISO image from the
contents of that directory.

You may find the following a useful guide if you can read my shell
script hacking: You will
want to replace the boot disk image with a suitable Mess-DOS boot
image. Once you've done that, xcdroast is your friend.
