I just did a preupgrade from F15 to F16 and fell into this trap, or something similar. >From a rescue disk boot (F12 is the latest I had lying around), I can see both grub and grub2 directories in /boot. The grub2 dir looks set up, but when booting grub/grub.conf is accessed, and it points to the preupgrade "kernel" which no longer exists. I tried setting grub/grub.conf so that at least the system would boot, but I can't figure out how to set the "root=" option. Using what's in grub2 does not work, nor does any of many things I've tried (it's /dev/sda2, and presumably VolGroup00-LogVol01, but nothing like that works). So, I'm dead in the water as well.
