1
00:00:00,180 --> 00:00:01,080
Instructor: Welcome back.

2
00:00:01,080 --> 00:00:02,220
So in the last lecture,

3
00:00:02,220 --> 00:00:05,939
we downloaded our installer file for VirtualBox

4
00:00:05,939 --> 00:00:10,050
and we also downloaded the ISO image for Kali Linux.

5
00:00:10,050 --> 00:00:12,810
Now it is time that we combine these two together

6
00:00:12,810 --> 00:00:16,440
in order to create our first virtual machine.

7
00:00:16,440 --> 00:00:17,610
But of course,

8
00:00:17,610 --> 00:00:20,400
to do that we need to install VirtualBox first

9
00:00:20,400 --> 00:00:22,710
with this installer file.

10
00:00:22,710 --> 00:00:25,950
So double click on the VirtualBox installer file.

11
00:00:25,950 --> 00:00:28,740
It will require administrator privileges.

12
00:00:28,740 --> 00:00:31,380
Simply just input your admin password

13
00:00:31,380 --> 00:00:33,390
and it will open this window

14
00:00:33,390 --> 00:00:35,910
welcoming you to the VirtualBox.

15
00:00:35,910 --> 00:00:36,870
Now it says here,

16
00:00:36,870 --> 00:00:40,620
the Setup Wizard will install Oracle VM VirtualBox

17
00:00:40,620 --> 00:00:41,580
on your computer.

18
00:00:41,580 --> 00:00:45,780
Click Next to continue or Cancel to exit Setup Wizard.

19
00:00:45,780 --> 00:00:49,380
We want to proceed, so I'll just click on Next.

20
00:00:49,380 --> 00:00:51,660
Here under the custom setup,

21
00:00:51,660 --> 00:00:54,120
I personally won't be changing anything.

22
00:00:54,120 --> 00:00:56,010
You don't need to change anything as well.

23
00:00:56,010 --> 00:00:58,140
You might want to change location

24
00:00:58,140 --> 00:01:00,600
if you prefer a different location to this one,

25
00:01:00,600 --> 00:01:03,240
but I do advise that you leave this location

26
00:01:03,240 --> 00:01:07,050
and that you just proceed to the next step by clicking Next.

27
00:01:07,050 --> 00:01:09,360
And here we got a warning that says,

28
00:01:09,360 --> 00:01:12,780
installing Oracle VM VirtualBox Networking feature

29
00:01:12,780 --> 00:01:15,030
will reset your network connection

30
00:01:15,030 --> 00:01:18,030
and temporarily disconnect you from the network.

31
00:01:18,030 --> 00:01:20,460
Now, it's just a warning that says

32
00:01:20,460 --> 00:01:22,170
you might be disconnected from the network

33
00:01:22,170 --> 00:01:24,000
while installing VirtualBox.

34
00:01:24,000 --> 00:01:27,330
Now in my personal experience this has never happened,

35
00:01:27,330 --> 00:01:29,220
but it might happen for you.

36
00:01:29,220 --> 00:01:31,410
So if you're doing anything important

37
00:01:31,410 --> 00:01:33,570
over the network at the moment,

38
00:01:33,570 --> 00:01:34,770
wait for that to finish

39
00:01:34,770 --> 00:01:37,890
and then proceed with the VirtualBox installation.

40
00:01:37,890 --> 00:01:40,230
I'll just proceed with the installation right now

41
00:01:40,230 --> 00:01:43,140
by clicking on Next or on Yes.

42
00:01:43,140 --> 00:01:44,550
And it will tell me

43
00:01:44,550 --> 00:01:46,980
that there are certain missing dependencies.

44
00:01:46,980 --> 00:01:48,900
Now, in order to install them,

45
00:01:48,900 --> 00:01:50,470
you simply just click on Yes

46
00:01:52,020 --> 00:01:54,300
and you click Install to begin installation.

47
00:01:54,300 --> 00:01:55,833
So I'll just click on Install.

48
00:01:57,240 --> 00:01:58,800
This shouldn't take too long.

49
00:01:58,800 --> 00:02:02,580
It might take 30 seconds or up to a minute

50
00:02:02,580 --> 00:02:04,890
for installation to finish.

51
00:02:04,890 --> 00:02:08,699
And once it finishes, we will get this window prompt

52
00:02:08,699 --> 00:02:12,780
that says Start Oracle VMware VirtualBox after installation.

53
00:02:12,780 --> 00:02:14,343
Want to click on Finish.

54
00:02:16,110 --> 00:02:18,870
And in just a few seconds, here it is,

55
00:02:18,870 --> 00:02:22,560
we get VirtualBox window opened.

56
00:02:22,560 --> 00:02:26,520
Now in your case, the window will not look like this.

57
00:02:26,520 --> 00:02:29,280
I already have some virtual machines installed.

58
00:02:29,280 --> 00:02:32,670
You won't have any of these machines installed

59
00:02:32,670 --> 00:02:34,440
on the left side.

60
00:02:34,440 --> 00:02:37,770
Your window will look something like this.

61
00:02:37,770 --> 00:02:39,570
Now it should welcome you to VirtualBox,

62
00:02:39,570 --> 00:02:44,040
but once again, you won't have these machines installed

63
00:02:44,040 --> 00:02:47,190
or available on the left side,

64
00:02:47,190 --> 00:02:48,450
but more about that later

65
00:02:48,450 --> 00:02:50,520
once we install the virtual machines.

66
00:02:50,520 --> 00:02:53,940
For now on, we are going to pretend as these don't exist

67
00:02:53,940 --> 00:02:57,450
and we're going to create our first virtual machine.

68
00:02:57,450 --> 00:03:00,420
So to create our first virtual machine,

69
00:03:00,420 --> 00:03:03,540
we want to click on this New button.

70
00:03:03,540 --> 00:03:06,600
If I click on New, it'll open this window

71
00:03:06,600 --> 00:03:09,150
where it will ask me certain questions

72
00:03:09,150 --> 00:03:11,640
about the virtual machine that I want to create.

73
00:03:11,640 --> 00:03:14,100
The first question is name,

74
00:03:14,100 --> 00:03:19,100
so I'll just call it Kali Linux 2023.

75
00:03:19,410 --> 00:03:21,000
I'll just leave it at that.

76
00:03:21,000 --> 00:03:22,620
You can call it whatever you want.

77
00:03:22,620 --> 00:03:24,210
You can simply just call it Kali Linux.

78
00:03:24,210 --> 00:03:26,010
It doesn't matter.

79
00:03:26,010 --> 00:03:29,520
Now what matters is this ISO image,

80
00:03:29,520 --> 00:03:33,120
here we want to select the ISO image of Kali Linux

81
00:03:33,120 --> 00:03:34,530
that we downloaded.

82
00:03:34,530 --> 00:03:37,620
So since it says that it is not selected,

83
00:03:37,620 --> 00:03:39,120
I want to click on here.

84
00:03:39,120 --> 00:03:42,210
I want to click on Other and simply just navigate

85
00:03:42,210 --> 00:03:45,360
to where you have your Kali Linux ISO image saved.

86
00:03:45,360 --> 00:03:48,600
In my personal case, it is on desktop and here it is.

87
00:03:48,600 --> 00:03:51,210
I'll just click it and click on Open.

88
00:03:51,210 --> 00:03:52,860
And you can see right here

89
00:03:52,860 --> 00:03:55,473
it selected a path to the ISO image.

90
00:03:56,550 --> 00:03:59,730
Under type, want to have it set to Linux.

91
00:03:59,730 --> 00:04:01,920
And under the version,

92
00:04:01,920 --> 00:04:04,320
if you remember from the Kali Linux official page,

93
00:04:04,320 --> 00:04:07,740
it said that it was Debian-based operating system.

94
00:04:07,740 --> 00:04:12,540
So ideally here we want to find Debian operating system,

95
00:04:12,540 --> 00:04:14,040
which is right here.

96
00:04:14,040 --> 00:04:16,380
We can see that it has bunch of versions,

97
00:04:16,380 --> 00:04:20,519
but we can simply just choose the regular Debian 64-bit.

98
00:04:20,519 --> 00:04:24,240
Now of course if you downloaded the 32-bit Kali Linux image,

99
00:04:24,240 --> 00:04:26,700
if your host machine is 32-bit machine,

100
00:04:26,700 --> 00:04:29,550
you can simply just use Debian 32-bit.

101
00:04:29,550 --> 00:04:32,490
Since I'm on Windows 11 64-bit machine,

102
00:04:32,490 --> 00:04:35,103
I will select Debian 64-bit.

103
00:04:36,390 --> 00:04:39,390
Once we do that, we can navigate to unattended install

104
00:04:39,390 --> 00:04:41,790
and there is nothing that we need to change right here.

105
00:04:41,790 --> 00:04:43,770
We can proceed to hardware,

106
00:04:43,770 --> 00:04:46,500
and here is where it gets a little bit tricky.

107
00:04:46,500 --> 00:04:47,580
Remember that I said

108
00:04:47,580 --> 00:04:51,270
that virtual machines will use your hardware resources?

109
00:04:51,270 --> 00:04:55,590
Well, here we need to allocate those hardware resources.

110
00:04:55,590 --> 00:05:00,120
Here the first question that it asks us is the base memory

111
00:05:00,120 --> 00:05:03,840
or RAM memory that we want to give to our virtual machine.

112
00:05:03,840 --> 00:05:05,820
Now, this will be different for everyone

113
00:05:05,820 --> 00:05:07,710
depending on what RAM memory

114
00:05:07,710 --> 00:05:09,870
or how many gigabytes of RAM you have.

115
00:05:09,870 --> 00:05:12,810
In my personal case, I have 64 gigabytes of RAM,

116
00:05:12,810 --> 00:05:15,690
so I'll just allocate four gigabytes of RAM

117
00:05:15,690 --> 00:05:17,310
to my virtual machine.

118
00:05:17,310 --> 00:05:19,290
Now, if you have less than 16,

119
00:05:19,290 --> 00:05:22,890
I do advise that you lower this to two gigabytes of RAM.

120
00:05:22,890 --> 00:05:25,170
For example, if you have eight gigabytes of RAM,

121
00:05:25,170 --> 00:05:28,110
two gigabytes of RAM for Kali Linux will be more than enough

122
00:05:28,110 --> 00:05:30,330
for it to run properly.

123
00:05:30,330 --> 00:05:31,950
If you have four gigabytes of RAM,

124
00:05:31,950 --> 00:05:35,010
then you can proceed with either two gigabytes

125
00:05:35,010 --> 00:05:38,670
or you can even try lowering it to one gigabyte of ram,

126
00:05:38,670 --> 00:05:41,550
but two gigabytes will be ideal.

127
00:05:41,550 --> 00:05:43,890
Now, once again, I'll proceed with four,

128
00:05:43,890 --> 00:05:45,810
and under the processors,

129
00:05:45,810 --> 00:05:48,780
you can simply just leave it on one CPU core.

130
00:05:48,780 --> 00:05:51,120
No matter how many CPU cores you have,

131
00:05:51,120 --> 00:05:52,560
it will work just fine

132
00:05:52,560 --> 00:05:56,100
with one processor running for the VM.

133
00:05:56,100 --> 00:05:58,500
Now we go down to hard disk,

134
00:05:58,500 --> 00:06:00,840
and here we want to allocate space

135
00:06:00,840 --> 00:06:03,450
for Kali Linux virtual machine.

136
00:06:03,450 --> 00:06:06,780
Now, by default, it will set it to 20 gigabytes,

137
00:06:06,780 --> 00:06:08,370
but that will not be enough.

138
00:06:08,370 --> 00:06:09,690
You ideally want to have it

139
00:06:09,690 --> 00:06:12,990
between 30 and 40 gigabytes of free space

140
00:06:12,990 --> 00:06:14,700
for the virtual machine.

141
00:06:14,700 --> 00:06:17,850
I will leave it on 40 just like this.

142
00:06:17,850 --> 00:06:19,290
This should be more than enough

143
00:06:19,290 --> 00:06:21,270
for the virtual machine to run

144
00:06:21,270 --> 00:06:25,800
and all we have to do right now is click on Finish.

145
00:06:25,800 --> 00:06:27,570
And once you click on Finish,

146
00:06:27,570 --> 00:06:30,330
you will have your first virtual machine

147
00:06:30,330 --> 00:06:32,940
added right here on the left side.

148
00:06:32,940 --> 00:06:34,953
In my case here is the vertical machine

149
00:06:34,953 --> 00:06:38,460
that we just created, Kali Linux 2023.

150
00:06:38,460 --> 00:06:42,060
If you click on it, you can see all of its settings

151
00:06:42,060 --> 00:06:43,380
on the right side.

152
00:06:43,380 --> 00:06:44,880
We can see that we allocated

153
00:06:44,880 --> 00:06:46,860
four gigabytes of RAM right here.

154
00:06:46,860 --> 00:06:50,820
We used Debian 64-bit operating system.

155
00:06:50,820 --> 00:06:52,800
And you can see all the other settings

156
00:06:52,800 --> 00:06:57,420
that we used to create this virtual machine.

157
00:06:57,420 --> 00:06:58,890
Okay, awesome.

158
00:06:58,890 --> 00:07:01,230
Now that we created this virtual machine,

159
00:07:01,230 --> 00:07:02,190
in the next lecture,

160
00:07:02,190 --> 00:07:05,130
we're going to start it for the first time

161
00:07:05,130 --> 00:07:08,400
in order to install the operating system.

162
00:07:08,400 --> 00:07:09,800
See you in the next lecture.
