Grub install to a ghosted partition ?
I have ghosted a partition of a remastered Xubuntu distro onto an external drive using "dd". The drive device name is /dev/sda3. This external drive will be used as a master drive to ghost onto a number of other machines to make installing the modified Xubuntu onto a number of machines quicker. So I need to install Grub to /dev/sda3 so that I do not have to load Grub on every ghosted machine. Thus I want the bootloader on /dev/sda3, not /dev/sda.
I am unsure how to get grub and its MBR properly installed properly onto /dev/sda3. Any ideas appreciated.
