If the operating system you have purchased is not already installed on your computer, we ask you to download an ISO file from our server. You can find the download links under  Sofortdownloads in your customer account (additionally you have received it by e-mail).
You can boot the downloaded file either by USB stick or DVD. To create a bootable USB stick or DVD, you need a program. We recommend the free program Rufus to use.
