Unable to install grub on an image

[kashyap garimella]

Hello everybody,

I want to install grub on an image. I created an image and formatted it using fdisk(to create partition table) and mkfs.ext3 to create an ext3 partition. I followed the instructions from this wiki page:

http://wiki.osdev.org/Loopback_Device

Then I installed grub.

Following are the list of commands:

$dd if=/dev/zero of=floppy.img bs=516096c count=1000

$fdisk -u -C1000 -S63 -H16 floppy.img # And create a partition table, following the link http://wiki.osdev.org/Loopback_Device

$losetup /dev/loop0 floppy.img -o0

$losetup /dev/loop1 floppy.img -o32256 # the ext3 partition starts from 63 sector(32256=63*512)

$mkfs.ext3 /dev/loop1

$mkdir mnt; mount /dev/loop1 mnt/

$mkdir -p mnt/boot/grub

$echo "(hd0) /dev/loop0" > mnt/boot/grub/device.map

$grub-install --root-directory=mnt /dev/loop0

Installation finished. No error reported.

And then I ran qemu on the image:

qemu -hda /dev/loop0

I get the following error:

error: no such device: ba16366d-55d7-445d-99e8-e4cd25287b16

I checked the UUID using blkid and it is same UUID in the error. I don't know why grub is unable to find that partition. Here are the results of fdisk and blkid:

$fdisk -l /dev/loop0 

Disk /dev/loop0: 516 MB, 516096000 bytes

16 heads, 63 sectors/track, 1000 cylinders

Units = cylinders of 1008 * 512 = 516096 bytes

Disk identifier: 0x0e5173d2

      Device Boot      Start         End      Blocks   Id  System

/dev/loop0p1   *           1        1000      503968+  83  Linux

$blkid /dev/loop1

/dev/loop1: UUID="ba16366d-55d7-445d-99e8-e4cd25287b16" SEC_TYPE="ext2" TYPE="ext3" LABEL="-v" 

I am using the latest stable grub:

$grub-install --version

grub-install (GRUB) 1.99~beta0

Can somebody help me in this. I am struggling to fix this from long time.

Thanks,
