I have a vaio laptop and it used to have installed windows 8 and Xubuntu 13.04 in dual boot, everything was working fine.

I decided to update my version of xubuntu 14.04 LTS mainly because the support for 13.04 is finished and LTS version have 3 years of support. What I did was to format the partition where xubuntu 13.04 was installed and install 14.04 in that formated partition. When I restarted my computer willing to start using my new system I got the following message:

error: symbol 'grub_term_highlight_color' not found

and I was not able to enter any OS.

I tried boot-repair from live USB more than two times and it did not fix the problem.

I tried to enter to my computer using super GRUB2 disk, however it does not apperar to work with UEFI active (besides super grub2 disk says it can) I only get the message "no operating system found".

If I boot super grub2 disk with UEFI disabled, super grub2 disk can not detect any OS,I also tried Rescatux distro, however, as of super grub2 disk, rescatux cannot enter when UEFI is active.

I tried boot-repair with the option of "restore EFI backups", after that I was able to boot on windows, but no grub menu appeared. I ran boot-repair again with no improving results

Here is the last Bootinfo report I got:

Do you have any idea of what is happening?

I really appreciate your help,
