I can confirm that , seems a grub problem doesn't add F17 kernel to
menu , and boots with F16 kernel

To me seems grub2 bugs and I see more 2 bugs, 
1- If have grub with some custom items, I don't know exactly what, I got
for example:   
background_image -m
stretch /usr/share/backgrounds/verne/default/normalish/verne.png

upgrade boot entry miss at least definition of root 
so I have to add  set root='(hd0,msdos1)' to upgrade boot entry. 

2- If I put load_video on upgrade boot entry , preupgrade boots with a
blank screen and I don't see any graphic, is a video problem. (I read
some bug block about this)  

Hope that can help something. 
ah and for recover a fail upgrade system , I got many tips here:

but be careful not all of document is correct and is a little old. 

Thanks,
