installing dual boot for asus x553m

i have tried to install ubutu alongside windows 8.1 pro  to asus x553m which have uefi bios,it goes normally but when i restart after completing installing it doesn't give dual boot option?

What boot loader are you trying to use? You need to have a boot loader running. After the bios the system should load the boot loader which will allow you which OS to boot into. In what order did you install the OS.
