Cannot Boot To Ubuntu After Installing Windows

Question

I installed Ubuntu 16.04, and after that I installed Window. After installing Windows, I cannot boot into Ubuntu. Both were installed into one hard drive, on two separate partitions. I did not format the partition I installed Windows. How can I boot Ubuntu?

Make a live Ubuntu USB or CD and boot to it.
Select "try Ubuntu without installing" Once there, open terminal and execute the following:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

After installing, open it by executing boot-repair and select recommended repair then follow on screen instructions.

After booting for first time You may not see Windows option, For that in Ubuntu terminal execute sudo update-grub to add all entries and you are good to go.
