Details:

I'm not sure this is a grub bug, but I didn't find any help in internet.

I have an USB Pen Drive with 2 primary partitions:
1st: 1.9GB FAT32
2nd: 130MB EXT2

I installed GRUB 2 on the second partition via ubuntu 10.04 with command:
grub-install --root-directory=/media/bootpart /dev/sdb

where "bootpart" is the name of 2nd patition and sdb is my pendrive



when I boot from this pendrive I obtain "error: no such disk" and the grub
rescue prompt. the only commands available are: insmod, set, ls.
ls returns an empty row
set returns: "prefix=(hd0,2)/boot/grub", "root=hd0,2"
insmod doesn't work with any module (always no such disk error)

if I give command "$root" I obtain: "unknown command 'hd0,2'"
