In this article, I will guide you step by step how to install CentOS 6.
Table of Contents
Some info from wiki:
CentOS (“Community Enterprise Operating System“) is a Linux distribution that attempts to provide a free enterprise class computing platform which has 100% binary compatibility with its upstream source, Red Hat Enterprise Linux (RHEL).[4]
As of versions 5.10 and 6.4, CentOS officially supports the x86 architecture with Physical Address Extension (PAE) and the x86-64 architecture, while a beta release is expected to be available for the PowerPC architecture.[5]
The first CentOS was based upon RHEL version 2.1AS, and was numbered as CentOS version 2.[1]
System Requirements:
- A physical machine with a cdrom or a thumb stick or a virtual machine.
- A CentOS 6.x installation media on a cdrom or a thumb stick
Let’s begin:
I’ll run the installation on a virtual machine but it works exactly the same as with a physical machine.
Step 1
So we begin with inserting the CentOS installation media to the cdrom/thumb stick and start the machine.
Once the computer will realize there’s a media in the drive it will automatically load it and it will look like that:

Press ‘Enter’ to select the first option, that is “Install or upgrade an existing system”.
Step 2
After 10 seconds or so you will see this window:

This step is a very legacy one, it was relevant for the old days when we used a cd to install the machine (rather than a thumb stick or an image).
I never let it test the media because i’m always installing from an iso image but if you feel the media might be damaged or corrupted then testing it can be smart, otherwise just use ‘Tab’ key to go to Skip and hit ‘Enter’.
Step 3
Use the mouse or ‘Tab’ key to get to the the Next button and click ‘Enter’.

Step 6
The installation notifies me that it couldn’t find any Linux related drives and makes sure that there’s no valuable information on the disk, I choose ‘Yes, Discard and data’:

Step 10
Choose the type of installation you would like to do as well as partitioning layout, in my case I always mark the “Review and modify the partitioning layout”, then click next:

Step 11
The default partitioning layout is displayed for last one inspection, if you would like to make any changes then now is time, click Next:

For example, let’s say I have 8gb ram in my machine and the default layout gives you only 4gb swap space, In that case I would take 4gb’s from the /home partition and add it to the swap partition.
If the layout is good for you, then simply hit Next.
Step 12
In this next step, you’ll be asked if it’s ok to format the drive, if it’s ok click ‘Format’:
