I wanna install grub on my flash drive for rescue usage.
My computer installs winxp, and I have fedora12 installed in vmware. I did like this:
step1: format the flash drive as FAT in winXP.
step2: in fedora12, mount the flash drive on /media/flash
step3: excute the command: grub-install --root-directory=/media/flash --no-floppy /dev/sdb.
in step3, It says: the file /media/flash/boot/grub/stage1 not read correctly. why?
In fact the command has created the flowing files on my flash drive:
.
`-- boot
`-- grub
|-- device.map
|-- e2fs_stage1_5
|-- fat_stage1_5
|-- ffs_stage1_5
|-- iso9660_stage1_5
|-- jfs_stage1_5
|-- minix_stage1_5
|-- reiserfs_stage1_5
|-- stage1
|-- stage2
|-- ufs2_stage1_5
|-- vstafs_stage1_5
`-- xfs_stage1_5
content in device.map is:
(hd0) /dev/sda
(hd1) /dev/sdb

It says: "/media/flash/boot/grub/stage1 not read correctly."
the same as what I post above.
You can't find it on internet, because my flash drive mounts on /media/flash/, the path is exclusively in my own computer. You can google "stage1 not read correctly" for some information. And they say it is may be the problem of /etc/fstab of /ect/mtab. But I can't find something unordinary in the two files.

I tried this, it says "Error 1: Cannot mount selected partition"
I think may be there are some hiden partition on my flash drive. In addition, the file system on my flash drive is FAT32. And I also tried formatting it as FAT, but it make no difference.
Code:
grub> root (hd1,0)
root (hd1,0)
Error 18: Selected cylinder exceeds maximum supported by BIOS
grub> root (hd1,1)

grub> root (hd1,2)
root (hd1,2)
Error 18: Selected cylinder exceeds maximum supported by BIOS
grub> root (hd1,3)
root (hd1,3)

This doesn't look like a partition table
Probably you selected the wrong device.

Partition table entries are not in disk order
I don't think it is a matter of real BIOS or not,because I had successfully installed grub on a kingston flash drive before. But it lost.
I just used the command: grub-install.
