Fedora 16 preupgrade problem?

I have a test machine with Fedora 15 x86_64 and ran preupgrade and all seemed to go fine. But after reboot, it comes up with the grub menu and option to upgrade to 16, but then selecting it just results in a blinking cursor in the upper left. No messages on screen, no disk activity. Currently downloading DVD image, but that saying it will take 5 hours more. +----------------------------------------------------------+ Michael D.
