First make sure that you are using the boot-only usb.img file. The full 
one was corrupted during upload and had to be removed:


Next, use DD as you've shown, make sure you dd the image to the root 
partition of the USB stick though, you should be overwriting everything 
on the stick since our image has its own filesystem data in it.

Lastly, you need to check your BIOS, and make certain it it set to boot 
from USB first, on my system here, each time I have to go into the BIOS 
and move the USB priority up to force it to boot from USB and not my 
regular drive.
