You can buy windows online and create a flash stick or DVD disc. It is possible to upgrade from earlier versions of windows to windows 8 without any discs too. I would recommend a fresh installation if you want to maximise your performance potential. Get windows 8.1
Start the computer with the flash stick or the DVD for windows 8 in the drive. If a windows 8 logo does not appear, you will have to find specific information on how to enable a boot override to start the setup from the media you have selected.
Be patient on the initial boot of the windows 8 disc, an image will sit on the screen for quite a while. There is no progress bar without an SSD or dated hardware in the installation procedure can be slow to get started. The computer will restart several times before launching the operating system for the first use.
