Wait... I missed this.
SGD 0.9799 is only "GRUB legacy" aware, which means that can only deal
with GRUB legacy installations, AFAIK.
Did you installed GRUB 2 or GRUB legacy into the USB hard disk?
- If you installed GRUB legacy you have to use SGD 0.97xx to try to boot
from there
- If you installed GRUB 2 you have to use SDG 1.98xx

I don't like that error :-/
***
25 : Disk read error
This error is returned if there is a disk read error when trying to probe
or read data from a particular disk.

But you can try with another menu option: "GNU/Linux → Boot GNU
Linux" (or Boot GNU Linux directly).
