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
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.
