CentOS 8 was released on 24.09.2019 with lots of new features. In this tutorial, we learn CentOS 8 installation on VirtualBox or on a Physical machine.

Step 1: Download CentOS 8 ISO Image

You can easily get an ISO image of all released versions of CentOS. On the website of CentOS, you can get the list of all available mirrors in the world. For better download speed choose the mirror in your region.

After Download the ISO image, you can verify the image with the size and SHA256 hash value given Here.

Step 2: Create a bootable USB drive

After download the ISO image the next thing we required is a bootable USB drive.

On a Windows PC, you can create a bootable USB of CentOS by using YUMI or RUFUS or LiLi. All are very simple and reliable ways to make a bootable USB.

If you on Linux then you can create bootable USB using the dd command like the below example.

sudo dd if=/path_to_iso_file/CentOS-8-x86_64-1905-dvd1.iso of=/dev/sdb status=progress && sync

Note: replace path_to_iso_file with your iso file path and also replace /dev/sdb by your USB device path. If you don’t know your USB device path you can run the below command to see it.

sudo lsblk
