Error 17 when loading GRUB menu from USB Flash

Hi

I have installed Ubuntu 8.04 on a 8GB Transcend USB Flashdisk. During the installation I made sure that the grub menu is installed on the flashdisk, and not the Windows MBR.

All went well with the install, however I now get Error 17 when the GRUB menu loads.

I have done some snooping around, and changed the drive order in the grub menu around. (hd1,0) instead of (hd0,1) originally. This has not had any effect.

I also downloaded the Super Grub Boot disk, but am not quite sure what I need to do with this tool to fix the problem.

I already have Windows and Ubuntu dual booting on my laptop.

Fdisk -l:

I also read somewhere that one should first try running fsck on the device. Results of fsch as follows:

:~$ sudo fsck /dev/sdb
fsck 1.40.8 (13-Mar-2008)
e2fsck 1.40.8 (13-Mar-2008)
fsck.ext2: Device or resource busy while trying to open /dev/sdb
Filesystem mounted or opened exclusively by another program?
:~$ sudo fsck /dev/sdb
fsck 1.40.8 (13-Mar-2008)
e2fsck 1.40.8 (13-Mar-2008)
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdb

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

Should I go ahead and run the "e2fsck" command?

Alternatively I could probably do a re-installation and disconnect the local HDD this time so the grub menu installation is doen properly?

Any assistance would be appreciated...
