Whew. So xorriso's ISO 9660 data are not to blame.

Bad news is that obviously the mere presence of a PC-BIOS Master
Boot Record keeps the operating system from mounting the image.
This MBR sits in a region where ISO 9660 (aka ECMA-119) allows
arbitrary system dependend data. So it is not standards conformant
to take offense and to refuse mounting.


Steve:
A simple solution might be little de-MBR programs in some widely
available interpreter languages, which get offered for download together
with the images:
  Seek byte 0, write 32 kB of zeros, keep all other bytes unaltered.

In any language this would run much faster than the dd copy method.


Have a nice day :)
