Ok, that apparently worked, it brought up a new, black & white menu with my 
old default boot at the top of the list, and then booted it before I had a 
chance to scroll up and down to see what was available.  What do I edit to 
extend that pause time to say 15 seconds?

Looking at /boot/grub2/grub.cfg, it added every old kernel version in my F10 
history, many of which have been removed from the /boot partition because 
anaconda will not allow a more than 200meg /boot.  In other words, a lot of 
trash that won't work is probably in the grub2 menu.  If I go clean all that 
up, how do it restore this to something sane, remove it and reinstall it 
again?  That seems a bit of a kludge.

Also, I note that in a quick scan, it didn't find either the mint 8 or 
mandriva installs although it did hammer on all drives for quite a while 
looking.
