I have installed Ubuntu 14.04.1 LTS. It is dualbooting alongside with windows 8. The computer is a VAIO SVE151G17M and they are booting from the EFI partition. Now the problem: When I start my computer it loads the grub asking for which SO I want to load. If I choose Ubuntu it starts normally and if I shut it down, when I turn it on again it will perfectly again. The problem is when I choose Windows! After turning the computer off when I turn it on again the grub won't show again and Windows will load again. It looks like no Ubuntu is installed. In order to be able to use Ubuntu again I have to set my bios to load as Legacy, restart (no SO will be found), then set BIOS to load from UEFI again, restart and everything will be normal again... Until I choose Windows :( I already tried Boot-Repair and it shows an error: http://paste2.org/kedKMUc6
What do you think is wrong?
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
