USB booting :: GRUB hanging when trying to boot from pendrive.

Thanks guys, but now I get another problem...

Code Sample

GRUB  version 0.91  (640K lower / 3072K upper memory) [ Minimal BASH-like line editing is supported.  For the first word, TAB   lists possible command completions.  Anywhere else TAB lists the possible   completions of a device/filename. ] grub> root (hd0,0) Filesystem type is fat, partition type 0xb grub> setup (hd0) Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... no Error 15: File not found

EDIT: OK, I spotted the obvious - partition 0 is FAT. I tried "root (hd0,1)" instead, and then the setup part gave some output that looked promising (can't paste it now, I've since rebooted). However, now when trying to boot from the pendrive I get "GRUB Hard Disk Error". At least I get three more words out of it before everything grinds to a halt. Any more suggestions?

OK, thought I'd post some info about the pendrive...

Output from fdisk...

Can nobody help me on this?

Cheers.
