Failed on grub installation

[Thiru]

Hi,

 

I have tried to create the disk image file to running ubuntu 12.04 (precise) machine using loop device. But  its failed during grub installation on the same.

 

I executed below commands

 

TMP=/mnt

 

...

 

LOOP=`losetup --find | cut -d "/" -f 3`

losetup -f --show  disk.raw

kpartx -av /dev/${LOOP}

mount /dev/mapper/${LOOP}p1 $TMP

 

...

 

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

 

 

Error message:

 

/usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/mapper/loop0p1.  Check your device.map.

Auto-detection of a filesystem of /dev/mapper/loop0p1 failed.

Try with --recheck.

If the problem persists please report this together with the output of "/usr/sbin/grub-probe --device-map="/tmp/tmp.eLpG2Ho5Ns/boot/grub/device.map" --target=fs -v /tmp/tmp.eLpG2Ho5Ns/boot/grub" to address@hidden

 

 

 

Thanks
