For many of you, who are looking for a Linux based distribution, which is community driven and has got an enterprise benchmark, CentOS is the best option without a doubt. It is a community based Linux distro which has its upstream source, Red Hat Enterprise Linux (RHEL). Traditionally, it is just a Linux distribution without certification and support, that’s the only difference between CentOS and other Linux based OS, like Arch, Mint, etc.
The only thing that you need to have is the CentOS downloaded ISO file. You can create a Centos bootable USB on the Linux platform for sure. But we will guide you through the ways to do the same on a Windows platform, since that’s the commonly available system to most users.
But before, we head on with the topic, you must know the difference between Minimal ISO and DVD ISO. These are two different variants of CentOS ISO available.
What are Minimal ISO and DVD ISO?
Basically Minimal ISO is a small sized CentOS distro, lesser than a GB. So after you download it to the required system, it downloads the necessary packages during the installation process. So if you have a fast network, then this is the best option for you.
However, if you don’t have a smoother and faster connectivity, DVD ISO will suit you best. It is larger in size and comes with full-fledged desktop installations and packages.
