I had a installation error, during base installation the installer couldn't download package libxi6 and aborted the process. I used your guide to manually partition the valve way (10/10/10/the rest for home) but no luck so far. The inet connection is an intel nic from an intel mobo works perfectly under win8. Sorry I can't provide you with logs atm as grub is blocking me from loading into win8. I used the latest version, I also tried the latest valve version, it installed but had problems with the mirrorlist but that's another story.
