Hi,
I would like to backup my entire Ubuntu installation (/boot, swap and /) at /dev/sda (4GB) to /dev/sdb (10GB).
I recreated the exact partitions on /dev/sdb, formatted and cp -rp all the files over.
For /boot, I used
dd if=/dev/sda1 of=/dev/sdb1
It didn't boot successfully as the system kept rebooting. I then tried to install grub onto the MBR and boot partition (mounted at /mnt/tempboot).
grub-install --force --no-floppy --root-directory=/mnt/tempboot /dev/sdb
But I get an error:
grub-setup: warn: Your embedding area is unusually small. core.img won't fit in it.
I read up more on this here (http://ubuntuforums.org/showthread.php?t=1528529).
Anyhow, since I forced grub-install, I believe the grub is installed. I rebooted the system and I get a grub prompt:
grub>
I am stuck here. Grub seems to not find my grub.cfg but it is present.:confused:
Can someone please help me? :(
