howto boot from harddrive

[kqt4at5v@gmail.com]

I just got a Guruplug server a couple of days ago. It booted right up as
described and I connected and all worked fine. Then I installed Debian as 
decribed at 'http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html'
to a USB flash drive. Also no problems everything works fine. Now I want 
to move the os to a USB harddrive. I partitioned the drive and copied the 
root and boot partitions from flash. When I boot I get

And that is as far as I get
Here is my environment
