Once the download completed, let us start to prepare the disk for installation.

To start with installation in a physical server first we need to download the ISO and burn it to a DVD, or we can create with a USB bootable media to start the installation. Here in our virtual server, we are about to use the ISO for installation.

Starting with Installation:

Once the ISO started to boot by default the selected option will be highlighted in second line “Test this media & install Scientific Linux 7.5” as shown below.

First installation screen

To familiar with available options in the installation screen navigate to all menus by choosing troubleshooting which will bring to know about available rescue, memory check. If the existing installation exists in our disk it can be booted from local disk.

Installation available menus

Press the return (Enter) key to start with the installation or wait for 5 seconds to start with the installation automatically.

Press Enter to start the Installation

In the next window, we will get the list of available languages to choose which need to be used during the installation process. By default, United States English will be selected. This will be mostly used as the US, If you prefer to change your require language selected from the available list and click continue.
