welcome to the video tutorial on
selecting a Linux distribution and types
of installation now that we know what
clinic says it is time we learn how we
should install it on the computer and
choose which distribution we should use
let's start by understanding what a
Linux distribution is well now as you
know that your next is an open source
free to use kernel it is used by
programmers organizations profit and
nonprofit companies around the world in
order to create operating systems to
suit their individual requirements these
versions types the kinds of Linux
operating systems are all distributions
or in the stores so how many
distributions are out there there are
hundreds of UNIX operating systems or
distributions available these days many
of them are designed with a specific
purpose in mind for example to run a web
server or to run network switches like
routers or modems the latest example of
one of the most popular smartphone based
UNIX distribution is Android so let us
learn about some popular Linux distros
starting with arch linux this linux
distro is popular amongst developers it
is an independently developed system it
is designed for users who go for a do
with yourself' approach
the next is the center force it is one
of the most used Linux distribution for
enterprises and web servers it is a free
enterprise class operating system and is
based heavily on Red Hat Enterprise
distro the next is Gen 2 it is a source
based distribution which means you need
to configure the code on your system
before you can install it it is not for
Linux beginners but it sure is fun for
experienced users Linux Mint it is one
of the most popular desktop
distributions available out there it
launched in 2006 and is now considered
with a fourth most used operating system
in the computing world next is Ubuntu
this is the third most popular desktop
operating system after Microsoft Windows
and Apple Mac OS it is based on Debian
Linux distribution and it is known for
its desktop and violent so which one is
the best Linux distribution well each
Linux distribution is built for a
specific purpose to meet the demands of
its target users most of the
distributions are available for free at
their respective websites you might want
to try them one by one till you get to
know which distribution you like the
most
each one of them offers its unique
design applications and secure it we
will be using Ubuntu for our learning
purpose as it's easy for a beginner to
understand
now let us look at the various methods
we can use to install Linux the first
type of installation is from the USB
stick this is one of the easiest methods
of installing Ubuntu or any other Linux
distribution on your computer so let's
start with the USB stick installation
for this you are going to need the
Ubuntu ISO or OS files you can download
them by visiting ubuntu.com forward
slash download or slash than stop
let's visit this page as you can see
here there are two versions of Ubuntu
available free for download let us go
ahead and download it will do 1210 the
second software that you are going to
need is a program which will install the
Ubuntu ISO files on the USB stick so for
this you can install the universal USB
installer available for free a pendrive
Linux comm so let us go ahead and
download it so once you have the given
to ISO files and the universal USB
installer downloaded on your computer
it's time to run the universal USB
installer the first step is about
selecting a Linux distro
the drop-down menu here shows the list
of different distributions and their
versions we will choose Ubuntu 1210
next you need to click on browse and
here we have that would do 12 10 ISO
files on the desktop so go ahead and
click on it
now you need to choose the USB flash
drive so let us go ahead and click on
this drop down menu here it shows that
we have a USB stake mounted on the drive
I so let's select it now if you want to
format the USB flash drive before it
installs Ubuntu you can click on format
the drive then click on create you would
get a pop-up message informing you that
the universal USB installer will work on
the following actions click on yes then
the universal USB installer program will
start moving the Ubuntu ISO files to the
USB stick once done you have the USB
stick ready with Ubuntu to install it on
your system so let us go ahead and click
on close now your USB stick is an
installation media with the window on it
now you can boot your computer through
this USB stick and you will be able to
run move into without installation the
second method of installation is by live
CD this is another effective way of
installing Linux on your system for this
you again need to visit ubuntu.com
forward slash download forward slash
desktop in order to download the ISO
files once you are done with the
download and you have open to
installation files on your computer burn
them to a CD and then you need to boot
your computer through the optical drive
and follow the instructions as they come
the next and the most popular method to
install a Linux operating system is
virtual installation it offers you the
freedom of running Linux on an existing
operating system already installed on
your computer this means if you have
Windows or Mac OS running then you can
just run Linux with a click of a button
virtual machine software like Oracle VM
can install Ubuntu in easy steps let us
look at them again you first need to
download the ubuntu iso files on your
computer then you need to download the
installation files for Oracle VM
VirtualBox as we are running on Windows
right now we will go ahead and download
these files so let us download and
install Oracle VM on the computer once
done you need to click on the Virtual
Box icon on your desktop and this is the
screen that will open then you need to
configure the virtual operating system
by clicking on new which will create a
new virtual machine you can have
multiple OS installations in your
virtual machine at the same time then
click on next type in a name for your
virtual machine and then choose the
operating system and the version that
you would like to install
click Next and define the memory size
for the virtual machine right now the
memory allocated for the virtual machine
is 512 and B you can always increase the
base memory size for the virtual machine
then click on next create a new hard
disk this does not create a new drive
like C D or E in your machine instead it
creates a VDI which is a virtual disk
image this virtual disk will contain
your OS installation click on next and
you will find that there are many
options to create a virtual disk choose
VDI which is VirtualBox disk image
select between dynamically allocated or
fixed size virtual disk storage a
dynamically allocated virtual disk file
with only you space on your physical
hard disk which is used by your VM
installation while fixed size will use
the entire allocated space in your
physical hard drive click on next define
the location for virtual this file on
your physical hard drive and the file
size the recommended file size is 10 GB
click on next you are then shown a
summary screen click on create and this
is the virtual machine that we created
so let's go ahead and power the virtual
machine
this will boot forward to on VirtualBox
now let's go ahead and install Ubuntu
if you want to download updates while
installing you can check this thick box
let's click on continue so if you want
to go ahead and install Ubuntu directly
you can choose this option here it will
not affect the hard drive instead with
only arrays the virtual disk that you
have created otherwise if you want to
work on the partitions you can choose
something else let's go ahead with
arrays' disk and install ubuntu right
now and click on continue
we can type in the city you live in here
and then you need to click on continue
then choose the language that you would
want to work with and click on continue
now this is an important step and it
will define your rights on the Linux
system so put in your name here and then
choose a computer name you will leave it
like this then you can put in a username
of your choice and after that put in a
password
then you can choose any of these two
options here and click on continue now
this would install Ubuntu on your system
those who want to test the distribution
before installing it on a computer and
replacing the existing operating system
would be surprised to know that you can
easily run it from the USB stick or a CD
in the trial mode as you can see here we
have a try ubuntu option available if we
go with it
Ubuntu would start in the trial mode and
you can easily check out the interface
this way you can learn whether you like
the distribution or not and can either
install or move on to another one
you can even install Linux side-by-side
with Windows or any other OS which is
called dual booting let us quickly
summarize what we learned today an
operating system based on the Linux
kernel
is called the distribution or distro
there are hundreds of distributions
available some of which are designed to
accomplish a sole purpose like running
servers act as network switches etc
naming the best Linux distribution is
difficult as they are made for different
needs Linux can be installed in your
system while the below mentioned methods
the first one is the USB stick the
second one is the live CD and the third
one is virtual installation thank you
for watching I will see you in the next
tutorial
