All the Linux distribution out there have the same way of installation. Well, I have learned my lessons while installing for the first time. I lost all the data of my precious HDD, actually twice xD.
There are lots of good tutorials out there on YoutTube how to install Linux Distributions. But before starting there are few things required to install the OS. Don’t be afraid Linux distros don’t require high-end hardware for practice purpose. Even you can work using your old PC/ Laptop or Virtual Machines.
Minimal Requirements to Install in your machine:
2 GHz dual-core processor
2 GiB RAM (system memory)
25 GB of hard-drive space (or USB stick, memory card or external drive but see LiveCD for an alternative approach)
VGA capable of 1024×768 screen resolution
Either a CD/DVD drive or a USB port for the installer media
CentOS 7 automated installation process using LVM (logical volume management). I prefer installing it manually. For manual installation, there are 3 partitions need to be created. They are:
Root ( / ) : 10 GB
Swap : RAM * 2 (if the RAM is less than 4 GB) / RAM * 1.5 (if the RAM is greater than 4 GB )
Home : After allocation spaces for Root (/) and Swap you can give rest of the spaces for Home Directory
Let’s jump into installing the robust Linux Distribution. You can check out the following videos for your reference.

These videos demonstrate only how to install CentOS 7 and other distributions installation process are almost the same.
