Default Ubuntu Touch for x64?

Sorry, i don't really get it yet... Does it run entirely on android? If so, how does it differ from launchers? And can it run on other linux kernel, specifically a x64 one? I would like to have a touch-friendly linux on my tablet which i could dual-boot with windows 8.1 (x64 version, not RT) without using any virtualizing, emulating, or buggy workarounds like android-x86...
