If you are only looking to update or upgrade CentOS, see How to Upgrade or Update CentOS.

Step 1: Download CentOS 7

To download the official and up-to-date CentOS 7 ISO file, navigate to https://www.centos.org/download/.
Our recommendation for non-enterprise environments is to download the DVD ISO option, which includes the GUI. We recommend the Minimal ISO option only for production enterprise environments.

Select DVD ISO option for CentOS 7 installation.

Step 2: Create Bootable USB or DVD

Now that you have downloaded the ISO image, you can create a bootable USB, burn it on a DVD or load the image on a VM.
Several applications can help you create a bootable USB. We recommend using Etcher. Download the application for your system (Windows, macOS or Linux), install and run.

  3. Find the USB and select it in the Select drive step.
