2
00:00:11,070 --> 00:00:13,470
What are the different ways to install an

3
00:00:13,500 --> 00:00:16,739
operating system? Well, there are many different

4
00:00:16,739 --> 00:00:19,410
ways but the most common ways I'm going to cover,

5
00:00:19,410 --> 00:00:22,770
there are three most common ways. And the first

6
00:00:22,770 --> 00:00:27,570
one is through the CD or DVD. Now you have a CD or

7
00:00:27,570 --> 00:00:30,840
DVD of an operating system, whether it's Linux,

8
00:00:30,870 --> 00:00:37,410
Windows, or Mac, the installation procedure of,

9
00:00:37,410 --> 00:00:39,750
or for installing an operating system is the same. The

10
00:00:39,750 --> 00:00:42,540
first one is you pop the tray out of your

11
00:00:42,540 --> 00:00:45,330
computer, whether it's a server or laptop or

12
00:00:45,330 --> 00:00:49,470
workstation, you pop the CD ROM drive out, insert

13
00:00:49,470 --> 00:00:54,300
the CD in, and then boot from CD. Now this is the

14
00:00:54,330 --> 00:00:58,290
most common way. And once the CD is installed,

15
00:00:58,920 --> 00:01:02,340
inserted, the installation program begins. The

16
00:01:02,340 --> 00:01:06,599
second way is through the ISO image, you install

17
00:01:06,599 --> 00:01:09,360
and or you actually download the image from the

18
00:01:09,360 --> 00:01:12,680
vendor website. Let's say if you're installing Red Hat,

19
00:01:12,680 --> 00:01:15,900
CentOS, Windows, you go to Red Hat website or

20
00:01:15,900 --> 00:01:18,900
you go to Microsoft website, you download the ISO

21
00:01:18,900 --> 00:01:23,010
image, you attach that ISO image to the Virtual

22
00:01:23,040 --> 00:01:27,480
disk of your computer. Now how do you access the

23
00:01:27,480 --> 00:01:33,000
virtual disk? Every computer has a console access.

24
00:01:33,060 --> 00:01:40,200
For example, Dell has iDRAC, HP has iLO, and so on

25
00:01:40,200 --> 00:01:41,910
so there are many different manufacturers have

26
00:01:41,910 --> 00:01:45,030
their different way of accessing the console. Once

27
00:01:45,030 --> 00:01:48,570
you access the console, you could attach this ISO

28
00:01:48,570 --> 00:01:51,240
image as a virtual disk and start the

29
00:01:51,240 --> 00:01:54,930
installation. In our lesson, this is what we will

30
00:01:54,930 --> 00:01:58,410
be following. The third method is the network

31
00:01:58,410 --> 00:02:03,270
boot. This is also common in bigger organization

32
00:02:03,270 --> 00:02:06,270
where they are building hundreds of computers,

33
00:02:06,270 --> 00:02:08,820
installing operating systems, 100 of them a day,

34
00:02:09,090 --> 00:02:12,570
that's when you need a network boot. Basically,

35
00:02:12,570 --> 00:02:16,800
you tell your computer to go to a specific IP, and a

36
00:02:16,800 --> 00:02:21,390
specific folder that is being shared by a shared

37
00:02:21,420 --> 00:02:25,020
server that could be either NFS server, or Samba

38
00:02:25,020 --> 00:02:28,650
server that attaches that file, you give in IP

39
00:02:28,650 --> 00:02:32,310
address and then you do the network boot. So these

40
00:02:32,310 --> 00:02:36,060
are the three common ways to do the operating

41
00:02:36,060 --> 00:02:39,960
system installation. And again, for our lesson we

42
00:02:39,960 --> 00:02:42,810
will be covering the second one which is the ISO

43
00:02:42,810 --> 00:02:46,050
download. We have already downloaded it and we

44
00:02:46,050 --> 00:02:49,740
will attach that ISO to our virtual environment

45
00:02:49,770 --> 00:02:51,030
and do the installation.
