Comment 4 for bug 1426905

Hi
I had this bug 2 years ago with ubuntu Unity. Since UEFI wasn't well supported (and documented) at that time, I tought it was the reason.

It appears that on my asus UX32VD, the fake RAID was the biggest trouble maker.
I get rid of it 3 weeks ago and was able to install ubuntu MATE 14.04 and 15.04 normally .
