I recently bought an asus s56c ultrabook, it cames with windows 8 pre-installed.
It's my first time with uefi technology so I'm not 100% sure of what I'm doing. :)
I disabled secure boot and I'm pretty sure I disabled fast boot too, I will attach a screen shot about this. Anyhow I successfully installed Lubuntu 12.10 from alternative cd and ubuntu 12.10 from regular dvd.
Now I cannot install Kubuntu: I downloaded kubuntu 12.10 amd64 iso and burn it to a dvd.
I pressed f2 and selected UEFI to boot my dvd.
Then I saw a screen selection like grub and I selected Try Kubuntu. The process started, I saw the logo of kubuntu and after a while everything stopped with a black screen.
I tried replacing quite splash with nomodeset in the options, but the starting process always stops at a different point.
What can I try now?
