efibootmgr -o sets the boot order in the firmware. We would actually need to see the output of sudo efibootmgr -v to make sure the command processed properly. Specifically, we'd need to see the line that begins with BootOrder.

my guess is that your firmware is hardcoded to always look cor the windows loader first. Even of you set tne boot order, every time it reboots windows defaults to the top of the list. Is there a hotkey you can press at boot to call the up a boot menu?Comment

That is not allowed in the UEFI specifications, I believe.Comment

it would not be the first time I have seen a half baked uefi implementation.Originally posted by SteveRiley View Post
All the OPs symptoms point to either efibootmgr being unable to write the NVRAM, or a hard coded preference for the windows boot manager. If there is no option in the firmware to toggled boot order he is screwed.
I have gigabyte hybrid uefi board that has been so much pain to install in uefi mode that reverted to a gpt/legacy boot with biosgrub partition.
At this stage I would suggest the OP try booting kubuntu from a refind ISO and then install refind from within kubuntu.
He may need to resort to renaming the refind boot file in the efi directory.
so far, Asus and lenovo seem to be the most well thought out UEFI laptops from what I have seen. Interestingly, I have a surface PRO from M$ that handles efi boot very well, with an absolutely minimal interface.

Sorry, mate for late reply... (bad connection in my area, couldnt online)Originally posted by mr_raider View Post
In this VAIO-SVF14212SG, it doesnt provide any "hotkey" which can call up the boot menu.
The access only through BIOS (by ASSIST button).
In their BIOS, in Booting section, only mentioning (which I think is related for this matter) :
- in Boot Configuration : Boot Mode (options: Legacy or UEFI)
- In Boot Priority, I only be able to move up /down the option(s) without able to modify each option.Comment

Do you see an ubuntu option in boot priorité?

Not relevant to the thread but I also have a Gigabyte motherboard (gigabyte-970a -dsp3 for amd) that for some reason is unable to install Kubuntu. What is even stranger is that I had kubuntu 13.10 installed last year and successfully upgraded to 14.04 but sometime last year grub couldn't load. After spending a couple of days trying to fix grub I bit the bullet and decided to go for a fresh install which always ended up with fatal error unable to complete grub install.Finally threw in the towel and decided to be happy ive still got kubuntu on the laptop.
Sorry for the thread jacking.Comment
