Last Friday (Black Friday, since I was in the US this year), I ended up buying for myself an early birthday present; I finally got the ZenBook UX31A that I was looking at since September, after seeing the older model being used by J-B of VLC fame. Today it arrived, and I decided to go the easy route: I already prepared a DVD with Sabayon, and after updating the “BIOS” from Windows (since you never know), I wiped it out and installed the new OS on it. Which couldn’t be booted.
Now before you run around screaming “conspiracy”, I ask you to watch Jo’s video (Jo did you really not have anything with a better capture? My old Nikon P50 had a better iris!) and notice that Secure Boot over there works just fine. Other than that, this “ultrabook” is not using SecureBoot because it’s not certified for Windows 8 anyway.
The problem is not that it requires Secure Boot or anything like that but much more simply, it has no legacy boot.
