[ubuntu] Ubuntu 14.04 "No partition active"

I installed only ubuntu 14.04 system on my computer (4T disk). As something wrong happened with the power supply, I cannot enter into the system when I restart the system.
It prompt " No partition active Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key".

I tried to fix by "lilo" and "boot-repair" tool, but it still not work.
The "boot-repair" retued info is post in http://paste.ubuntu.com/23100635/

Thanks in advance for your kind help.
