GRUB -- how to make the secondary drive the primary boot drive

[Robert Swanson]

	I am running Kubuntu 6.06 and I have a problem with grub.  I was originally 
running the system as a multi-boot system.  I had other systems on my primary 
drive, hda, and Kubuntu is on my secondary, hdb.  The problem is that my 
primary drive is dying and I am having a problem configuring grub so that I 
can remove the primary drive and make the secondary drive my boot drive.
	I attempted to install grub on my secondary drive, but the problem is that 
when I pull the primary drive, I can't get the system to boot.  I have tried 
putting the secondary drive on the primary cable and it still wouldn't boot.   
	I have a boot partition on hdb with what I believe are all the grub files, it 
is also set as the boot drive.  
	Any help to enable me to successfully remove the primary drive and make the 
secondary my boot drive would be appreciated.  I have all my files backed up 
and am all ready to go.
