After downloading the RHEL from RedHat web site, we can proceed with the installation. Here, we have explained step by step Linux installation with screen shots.
Note:
Whatever installation we are doing that is for our lab purpose only. In reality when we work in an organization, we don't actually download the software from website and we don't follow graphical installation steps. Please keep this in mind.
