Preupgrade with multiboot: can't find right target

Hi: I'm new to this list and haven't found a searchable archive, but I 
haven't seen this topic in Google.

My box came with MS Vista and I initially added f10, which was fully 
updated until near EOL.  Later I added a second disk and f12, and 
recently I used preupgrade for f12-to-f13.  That went well, and I 
decided to try f10-to-f14.  The packages were identified and put into 
cache and after I had copied the new lines in grub.conf from disk 1 to 
disk 2 the upgrade entry appeared in the Grub menu.  The kernel boots 
but I don't think it sees the preupgrade cache and the only option 
offered is to upgrade the f13 system.  I don't want to do that.

I've tried various modifications to grub.conf without success.  One 
recent iteration is below.  The f10final and f13 entries, and the MS 
related ones, all work and I've left the f10release entry in case it 
holds useful data.  I downloaded the f14 installer and when I specify 
its location on disk 2, (/dev/sdb1  /install.img) it runs.  Again, the 
location specified in grub.conf apparently doesn't get used, although 
it's there too.

TIA,  John P.
