What are the different ways to install an
operating system? Well, there are many different
ways but the most common ways I'm going to cover,
there are three most common ways. And the first
one is through the CD or DVD. Now you have a CD or
DVD of an operating system, whether it's Linux,
Windows, or Mac, the installation procedure of,
or for installing an operating system is the same. The
first one is you pop the tray out of your
computer, whether it's a server or laptop or
workstation, you pop the CD ROM drive out, insert
the CD in, and then boot from CD. Now this is the
most common way. And once the CD is installed,
inserted, the installation program begins. The
second way is through the ISO image, you install
and or you actually download the image from the
vendor website. Let's say if you're installing Red Hat,
CentOS, Windows, you go to Red Hat website or
you go to Microsoft website, you download the ISO
image, you attach that ISO image to the Virtual
disk of your computer. Now how do you access the
virtual disk? Every computer has a console access.
For example, Dell has iDRAC, HP has iLO, and so on
so there are many different manufacturers have
their different way of accessing the console. Once
you access the console, you could attach this ISO
image as a virtual disk and start the
installation. In our lesson, this is what we will
be following. The third method is the network
boot. This is also common in bigger organization
where they are building hundreds of computers,
installing operating systems, 100 of them a day,
that's when you need a network boot. Basically,
you tell your computer to go to a specific IP, and a
specific folder that is being shared by a shared
server that could be either NFS server, or Samba
server that attaches that file, you give in IP
address and then you do the network boot. So these
are the three common ways to do the operating
system installation. And again, for our lesson we
will be covering the second one which is the ISO
download. We have already downloaded it and we
will attach that ISO to our virtual environment
and do the installation.
