This is my first time installing Ubuntu 16.04. I have Windows 8 on my PC, and I downloaded Ubuntu 16.04, put it on a DVD then installed it on my PC.
When I turned on my PC after installing Ubuntu 16.04, no GNU Grub appeared. No option to choose Ubuntu or Windows. It directly booted-up Ubuntu 16.04.
I searched for an answer. I followed suggestion by installing Boot Repair.
open a new Terminal, then type: sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update Press Enter Then type: sudo apt-get install -y boot-repair && boot-repair Press Enter
Now, GNU Grub shown up. But no option for Windows. It's just:
Ubuntu Advance Options for Ubuntu
Now I do not know what to do. I need to work and access my document on windows 8.
