boot.img.gz is *just* the boot loader.
To make it function you *must also* copy an .iso image to the USB-stick
- or else it gives your *that* message. :-)

HowTo:-
wget hd-media.img
wget cd.iso
dd if=hd-media.img of=/dev/stick
mount /dev/stick /mnt
cp cd.iso /mnt
umount /mnt

The netinstall contains a bootloader.....
# parted debian-6.0.0-i386-netinst.iso print
debian-6.0.2.1-i386-netinst.iso: 198MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

ISO-hybrid boot is tricky - and is not supported on all machines (and
even then sometimes required fiddling with the BIOS).
It also doesn't play well with multi-arch...
There are issues with jigdo (which you are strongly encouraged to use
when downloading CD/DVD images):-

Additionally the CD/DVD images are designed primarily for CD/DVD
installations, so I'm guessing that's the prime consideration when
choosing a boot scheme.
You might want to check that CD2 doesn't have ISO-hybrid boot... in the
dim past I've been able to boot from the second CD when the first CD
wouldn't.
Coverting a standard ISO image to an ISO-hybrid image is not hard either.

Quick way
# cat debian-6.0.2.1-i386-netinst.iso > /dev/stick
# parted /dev/sde print
Model: TOSHIBA TransMemory (scsi)
Disk /dev/sde: 1999MB

Needs the boot.hd.img (first).
