I have a Samsung NP740U3E with pre-installed Windows 8 (boots with UEFI). I installed Ubuntu 13.04 without problems. Later, Windows 8 did a BIOS update which messed up everything, nothing would boot. I recovered everything and went back to fabric settings.
Now Windows 8 works fine, but when I try to install Ubuntu it does not detect any operating system, so I can`t install Ubuntu alongside Windows.
I`ve googled as much as I can, ran a boot-repair, disabled fast- and secure-boot. I have a GPT disc, been looking into gdisk without luck.
Here`s my boot-repair summary http://paste.ubuntu.com/5835719/
Is it necessary to convert the GPT disc to MBR? Is it possible to hard-reset the disc "even more" than fabric settings?
Thanks in advance.
