[Ubuntu] Boot-Repair

Hello!

I have my laptop with dual boot (Windows 8.1 and Ubuntu 16.04) and today I managed to upgrade the version of Windows.

The update messed up my GRUB and the menu grub rescue appeared after rebooting.
I used the tool Super Grub2 Disk to boot to Windows, although it did not find any grub files to boot to Ubuntu OS.

After that, I made a Live USB with Ubuntu 16.04 image and tried to run Boot-Repair to restore the GRUB, which was not successful.

Here is the report from Boot-Repair after I tried to repair: http://paste2.org/YwNxMx6D

I would like to ask if somebody is able to help me with this issue.

Thank you very much!
