Well whatever, I added that line as shown below, but still get the same 
error when I run preupgrade.

    #boot=/dev/sda
    default=1
    timeout=10
    splashimage=(hd0,0)/grub/splash.xpm.gz
    hiddenmenu

However when I run fdisk on that computer it shows two drives flagged as 
boot. It boots from /dev/sdb. And I see there is an error in the 
partitioning on /dev/sda. I wonder if that can cause confusion? It 
certainly hasn't bothered F-11, I never noticed before. I would have 
tried removing the other boot "*" but I'm not sure if telling it to 
write that will cause other problems, with it all being lvm I don't know 
if anything is written to that disk that I need? I have a strong 
temptation to run fdisk and fix that! Any suggestions ...

    cat fdisk.txt

    #    fdisk.txt

        Device Boot      Start         End      Blocks   Id  System
    /dev/sda1   *           1          26      204800   83  Linux
    Partition 1 does not end on cylinder boundary.
    /dev/sda2              26       30401   243991201   8e  Linux LVM


        Device Boot      Start         End      Blocks   Id  System
    /dev/sdb1   *           1          13      104391   83  Linux
    /dev/sdb2              14        9729    78043770   8e  Linux LVM

Also I never removed the parts of grub.conf that refer to the kernels I 
removed before starting this exercise.
