hidden file on an iso-image ?

[Helmut Jarausch <jarausch@igpm.rwth-aachen.de>]

Hi,

I have an ISO image of 300 Mb which is said to contain software for
Linux and for Windows.
When I burn it onto a CD and mount it or when I mount it directly as
loop device,
I can only see the Linux part ( du -sm shows 144 Mb only).
When I look at it under Windows I can only see the Windows part.

Is there any means to access everything under Linux?
And how can I create such an image?

Many thanks for a hint,
