unable to boot from memory stick

[pol <linux_milano@yahoo.it>]

hi all, 

I am trying to boot my  hp tablet tc4200 from the usb memory stick, so as to
be able to install debian on it, yet booting fails due to "missing
operating system"
 
I have followed instructions from   http://d-i.pascal.at/  
and used 1gb 'dikom' memory stick.

Any ideas?

Thank you for your help
