I want to change my OS from windows to UBUNTU. So what I did is below.
I downloaded the Ubuntu 16.04.3 LTS
from here saved it in a usb and set the boot order of USB to be the first boot in BIOS. But the installation failed.
What causes the installation to fail? after saving the changes in BIOS the laptop restarts and goes to windows
Additional information
Laptop is new and i am installing to change os to practice programming better.
