Yesterday when i restarted my computer it is showing screen with error :
No bootable devices found
So I am trying to restore my grub file using this guide but my boot repair doesn't have both options as shown in the answer. It looks like this :
and Paste from boot-repair is : http://paste.ubuntu.com/12243513/
How to proceed now?
You need the Universe repositories to install gksu. Therefore
Open Software and Updates and use the first tab Ubuntu Software and select the line Community-maintained free and open-source software (universe)
After that, install the package via:
sudo apt-get install gksu
Now start boot-repair again.
Or the terminal way:
Open the file /etc/apt/sources.list:
nano /etc/apt/sources.list
and check the following lines to use the universe repositories:
deb http://archive.ubuntu.com/ubuntu/ trusty universe
deb http://archive.ubuntu.com/ubuntu/ trusty-updates universe
deb http://security.ubuntu.com/ubuntu trusty-security universe
