I have no problems configuring the boot order in the BIOS.
I must have the MBR on /dev/hdc (which is being removed).
The /boot partition is on /dev/sda (where I want to move MBR).

sda = old MBR source and sdb = new MBR source, I assume?
So, in my instance, I'm going to want to run it in this syntax:
dd if=/dev/hdc of=/dev/sda bs=512 count=1
I'm assuming the first 512 bytes are allocated purely for MBR and
won't hold any data that could be overwritten? Would that be true?

Do I need to move the MBR, remove the old drive, and reboot from
a LiveCD in order to have a reconfigure of grub correctly see which
drive it should find to boot from? Or can I do this before taking the
system down for the drive removal?
Thanks,
Scott
