When I turn on the computer, the keyboard lights up just fine. And everything else works fine. It is just that I can't boot from anything but my /boot, with its functioning grub.
In other words, the computer works fine, except that it can boot only from the SW I have in my /boot and /boot/grub directories.
So apparently what you need to do is get into BIOS setup, and change the boot device priority order to make DVD and/or USB higher priority than HD. In my MSI military class motherboard BIOS it can be done with mouse on the "boot device priority bar", which starts just a little bit below the great big digital clock top center.
