Option 1:

Click Recovery then click Get Started under Reset this PC
Since we are performing a clean install, I will be selecting the option Remove everything, if you don't want to do that, you can click Keep my files
Reset offers two types of clean installs:
Just remove my files - this option is quicker and recommended if you just want a fresh start and you plan to keep the computer.
Remove files and clean the drive - if you plan to giveaway or resell your computer, this option ensures the computer is cleaned properly. Its takes a bit longer, but it is recommended if you plan to no longer use this computer.
Since I will be using this computer, I will choose the first option.
