view story

http://ubuntuforums.org – Hi I have managed to install OSX Mountain Lion on my macMini Mid 2010. This was not easy see https://discussions.apple.com/messag...23456#19063113 for further infos. I am not able to boot into ubuntu anymore. :( When i press the ALT key on boot i only see 2 Volumes "macintosh HD" and "Recovery HD". The 3rd named "Windows" (with ubuntu grub2 boot) is not available anymore (before installing ML it was there). This are the infos refit prints with partition inspector: Code: *** Report for internal hard disk *** Current GPT partition table: &nbs (Hardware)
