Bootstrap loader error

[sbfee]

Hi:
I made a USB that hangs before the installer boot menu appears ( Figure 2.3.1.). The same USB boots my laptop to the install menu and the target machine boots from USB with Knoppix. The errors look like 0xaa and are displayed in the picture. Any suggestions on how to debug are appreciated. Thanks, scott

While not much help, I ran into a similar error with my CD image. The image writer that I used competed a hash verification so I feel the disk write was accurate.
I have had no luck with USB sticks either.
