Boot from the installation media. (USB/DVD)

This step is gonna be different for every Computer. Once you pass through it, the installation process will be pretty much simple after it. Ok, so normally, when you turn on the PC, Windows does boot from hard disk or SSD. So you just have to pause that startup process and boot from USB Drive. So that you can install Ubuntu. And, you can do that from BIOS settings.

In my PC, I am using an Asus motherboard. By pressing F2 and Delete key I can enter into BIOS settings. And, can set the boot priority.Select Boot Priority

In my HP laptop, by pressing Esc key I can pause the startup process. And, with the F9 key, I can enter into the boot manager. And, from there I can select the USB Hard drive.Boot from USB Drive

So, what you have to do is, enter into your BIOS settings. And, set USB drive as first boot priority. You have to turn off your computer, and, press the power key. Before it gets starts, press the certain key (Esc, Delete, F11 or F12, but it varies by manufacturer.) to load boot menu. And, select installation media from the list.
