Thanks for all your feedback guys, so based on your feedback that grub is
confused i thought i give it a go to prep the USB harddrive with the
netinstall image instead of running it from the USB stick.
So i did the following (from another Debian)
zcat boot.img.rz > /dev/sda
mount /dev/sda /mnt
cp initrd.gz /mnt (from the netinstall)
umount /mnt
And this time i only booted the machine with the USB HD attached and the
installer booted and run happily from the USB HD
i proceeded with the installation and selected /dev/sda as the partion to
put grub on
Reboot.... and still the same problem is there (no boot entries). also tried
the grub commands suggested but when i do root ( <tab> i only get fd0. and
the finds dosn't work
Then i tried to install grub on
/dev/sda1
dosn't boot at all
making the partition reiserfs instead of ext3
Grub error 17
after doing a rescue and grub-install /dev/sda
Grub error 18
So my guess is either
a) The USB-HD isn't supported ( which seems a bit unlikely as it boots the
installer )
b) Some weird restriction exist in the hardware to boot from a USB-HD
c) Im doing some stupid mistake that I'm not realizing
I can't really come up with anything what to do next if you guys have any
more suggestions please let me know
Thanks

It should work. You need to repartition the USB drive and reinstall
Debian onto it. But as you do the install, you need to appreciate the
fact that you'll install Grub to a different device specification than
it will boot from.
That is to say, you'll install both Debian and Grub to /dev/sdb (USB
disk), but when the machine boots, Grub should see /dev/sda (USB disk).
IOW, configure Grub so that it wants to boot from /dev/sda, but install
Grub to /dev/sdb. That's the best I can do to explain it; I doubt this
is possible with Grub, but I think it's possible with Lilo.
Anyway, good luck.
