Boot up a live cd that is the same version and bit as your Ubuntu OS. Use boot-repair to reinstall grub. Here is how first open up a terminal in put in this code.
Installing boot-repair
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
than
sudo apt-get install -y boot-repair && (boot-repair &)
Opening boot-repair
sudo boot-repair
Using boot-repair
Then puss "Recommended repair" and before that, you need to make sure the default setting is right for your system, so just look over the Advanced options.
After you have done that reboot your computer and you will see grub again!
