I have a Samsung Series 9 (NP900X3D) laptop. Previous versions of Ubuntu worked with UEFI but by both updating over-the-air from 14.04 and by doing a fresh install from the live CD burned to a USB stick (by using existing partition table or by zapping it and creating a new one), the system refused to boot at all with 14.10.
This is very much a bad bug as it's taken me 5 days to get this fixed! Killing boot is a fairly big showstopper! >From the above thread, jorisc90's note from point 4 was the fix for me. The laptop now boots again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1363719 Title: efibootmgr may create a duplicated boot entry, "breaking" UEFI boot.
