I tried to install the Fedora 11 - Alpha DVD on my IBM ThinkCentre (8183) system but could not. The DVD boots corectly and gets past the media check. It then notices that one of the dirves in the system is partitioned GUID/GPT for apple HPFS+.
I select to ignore the drive - I plan to install on one of the MBR partitioned drives. At that point I get an error panel and the install fails. This did not happen with fedora 10 using the same drive configurations.
If there is a better/official place to file bug reports please point me to it and I will make a report there.
