Actually I only had to leave it alone for 15 minutes and the 
installation proceeded. The installation is complete now. I noticed the 
installer didn't let me make any software installation choices - I guess 
it knows what's good for me. Going back to the step-by-step I was 
following, I'm now advised to do this (so that the second hard drive 
will boot should the first hard drive crash):

sudo grub-install /dev/sda
sudo grub
grub> device (hd0) /dev/sdb
grub> root (hd0,0)
grub> setup (hd0)
grub> quit

Is this wise counsel?
