Emmanuel, I used a totally different approach by using VMware: the trick is to install on a physical device which is the USB drive. When the installation requests a reboot, simply boot on your USB and off you go!

Any ideas how I can probe/list devices within grub shell? I've done the stupid method of root(hd0,x) all the way up to root(hd8,3) without luck.
Have you tried the grub "find" command? find /grub/stage1 find /boot/grub/stage1 etc.
