I was running Fedora 13 and used preupgrade to upgrade to Fedora 15. The preupgrade ran without error but when I rebooted I had a problem. The grub menu appeared with all the previous Fedora 13 kernels from which to boot and a top menu item which said "Upgrade to Fedora 15". Choosing the latest Fedora 13 kernel was no problem, and I was able to boot back into Fedora from it but attempting the "Upgrade to Fedora 15" menu item instead shows a cursor in the upper left hand corner of the screen and nothing further happens no matter how long I wait ?
Does anybody have any suggestion in making preupgrade actually work, or am I just better off burning a Fedora 15 DVD and trying to upgrade from that ?
