Hi,
I think there is some sort of issue with isolinux.
In 14.10 isolinux changed A LOT....
So I think there is something that doesn't always go right making
startup disks for:
  versions > 14.10 when using <=14.04
  and using >=14.10 to make disks for <14.10

This has effected startup disk creator, if I remember right (don't quote
me on this... I just think I remembered finding this out when
discovering isolinux in 14.10 was not the same as I was used to in
12.04->14.04)

Of course the easy work around is to use mkusb, as it simply writes the
file to your USB, and doesn't care much what version of ISOlinux you are
using as it does not chroot your USB or anything complicated... it just
uses dd very safely.  It defaults to USB only mode, and makes you double
check that this IS what you want to do first.
