> The BIOS determines which disk (the first) will be chosen to boot from. 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). > To make a plain bootsector copy: > dd if=/dev/sda of=/dev/sdb bs=512 count=1 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? > grub > root (hd0,1) # press tab for command completion > setup (hd0) 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
