The boot manager for Ubuntu, GRUB2, was probably broken when you were installing updates. Try using Boot Repair to fix it. First boot to the Ubuntu live CD. Open a terminal window and run the following code to install and run boot repair:
sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair
boot-repair
Then follow the instructions and options in the program to repair your boot.
