When I booted from the alt CD and selected "boot from first hard disk" I ended up at the "grub rescue" prompt. So I rebooted again from the alt CD and selected "rescue a broken system". Ran grub-install and rebooted. Still will not boot from /dev/sda. But now it will boot /dev/sda if I first boot from the alt CD and select "boot from first hard disk".
