So I originally had live media for fedora 17 long story short I decided to use Fedup to get to fedora 19 rather than downloading fedora 19 media.
I installed f17 with no issues and updated my installation of f17. I then ran
yum --enablerepo=updates-testing install fedup sudo fedup-cli --network 19
and checked the log file as instructed.
When no issues were found I rebooted to begin the upgrade process. I let it run until the ASCII hotdog guy appeared and the process appeared complete without any problems occurring that I could see. So I hard rebooted and found myself in the grub menu. when I try booting f19 when the fedora icon fills up it immediately reboots. I tried rebooting to f17 which also crashes. I also tried selecting 'fedora linux' in grub which appears to load up crashes and logs out when I try to log in.
I've tried googling, looking through the fedora 19 common bugs area and through the forums here but I can't find much that matches my issue.
