How to install Ubuntu on budget laptop Lenovo ideapad 120s £179 laptop

In this video I unbox the Lenovo Ideapad 120s with 4GB of Ram and 32GB of Hard Drive Space. The laptop has Windows S on it but due to the small hard drive space, basic underpowered processor and shared Ram it does not cut the mustard even for normal use. The Ideapad is good for one task at a time under Windows, and mainly should be used to consume media and not do any kind of office/school work. It has a great build quality and a decent keyboard and an up to 8 hour battery, so it's an ideal candidate to upgrade to Ubuntu 18.04.
