    Thumbs up Grub To A Specific Partition


    I have a dual boot (windows & Ubuntu 12:10) dual drive system. I am trying make the second drive an image of the first, so that if the first one fails, I can boot the second.

    I am using the mbr built by easybcd to allow me to boot Windows or Ubuntu. If I select 'Ubuntu', i get directed to Grub on my Ubuntu partition. All is aok here.

    I have already duplicated the Windows Partition, and it boots fine.

    I just used GParted to copy my Ubuntu Partition - SDA4 >> SDB4. That seemed to work fine.
    As expectecd, Ubuntu on SDB4 is an ext4 partition. However, I noticed it's mount point is '/mnt'. I don't know why it is not '/'.

    I then tried to install GRUB on SDB4:

    sudo mount /dev/sdb4 /mnt
    sudo grub-install /dev/sdb4 --force

    and I get the message:

    /usr/sbin/grub-bios-setup: warning: File system `ext2' doesn't support embedding.
    /usr/sbin/grub-bios-setup: error: embedding is not possible, but this is required for cross-disk install.

    What gives?
