I have a HP Envy 4 ulrabook with windows 8 and SSD.
I'm trying to follow the steps given in this thread http://ubuntuforums.org/showthread.php?t=2108450.
I have disabled secure boot & Intel rapid smart technology from the BIOS. When I try to install using a Live USB, for the screen to select the "Installation type" I get a error saying "Sorry, Ubuntu 12.10 has experienced an internal error". On selecting the show details option it shows the executable path as "/usr/lib/ubiquity/bin/ubiquity". In this "Installation type" selection screen I do not get any option to select device or partitions. All options are disabled.
