00:00:01,166 --> 00:00:06,266

Hello everyone, in the previous course we have completed the production of PE disk

2

00:00:06,566 --> 00:00:10,333

In the next lesson, we start the real system installation

3

00:00:10,800 --> 00:00:14,366

Let's first look at the process of system installation

4

00:00:15,333 --> 00:00:22,200

To install a system, you must first enter the BIOS and change the startup item to U disk boot

5

00:00:23,366 --> 00:00:27,166

The purpose of this step is to allow the computer to boot from the U disk

6

00:00:27,466 --> 00:00:31,966

When the computer has multiple hard disks, for example, when reinstalling the system,

7

00:00:32,500 --> 00:00:34,900

there is already a system in the hard disk of the computer.

8

00:00:35,200 --> 00:00:37,800

If we do not change the startup item to U disk boot,

9

00:00:37,866 --> 00:00:43,333

then the computer will still start from its own hard disk

10

00:00:44,066 --> 00:00:49,300

After modifying the startup items, we next restart the computer and enter the PE of the U disk.

11

00:00:49,966 --> 00:00:54,800

After entering the PE, partition the hard disk according to the needs

12

00:00:55,133 --> 00:01:01,133

After partitioning, run the installation tool that comes with PE to install Windows

13

00:01:02,000 --> 00:01:06,300

After the Windows installation is complete, you need to restart the computer

14

00:01:06,500 --> 00:01:11,800

After restarting the computer, the computer will automatically complete the next Windows installation

15

00:01:12,533 --> 00:01:15,333

Next there will be some options for us to choose

16

00:01:15,466 --> 00:01:20,933

After the selection is made, the system installation is completed and the system desktop is entered.

17

00:01:21,466 --> 00:01:27,133

After entering the system, we need to use the driver package in the U disk to install the driver

18

00:01:27,966 --> 00:01:33,566

When all the drivers are installed, the system will complete the installation

19

00:01:34,233 --> 00:01:37,066

This is the general installation process

20

00:01:37,833 --> 00:01:41,466

Next, let's see what each step looks like

21

00:01:41,800 --> 00:01:44,066

The first is to enter the BIOS

22

00:01:44,800 --> 00:01:49,200

Entering the BIOS generally requires a shortcut key to enter.

23

00:01:49,600 --> 00:01:57,933

Here are some shortcut keys for entering the BIOS of different brands, for your reference only.

24

00:01:58,066 --> 00:02:04,933

Because different series of computers of the same brand may have different shortcut keys to enter the BIOS.

25

00:02:05,866 --> 00:02:09,566

For example, we are using a desktop computer this time

26

00:02:09,866 --> 00:02:16,066

The shortcut key for desktop to enter BIOS is Delete, or ESC, or F2

27

00:02:16,733 --> 00:02:19,333

So how to use this shortcut key?

28

00:02:19,766 --> 00:02:24,966

We need to press the shortcut key frantically after pressing the power button

29

00:02:25,833 --> 00:02:31,966

If you are not sure it is a certain shortcut key, you can press all the suspected keys,

30

00:02:31,966 --> 00:02:35,500

so that you can enter the BIOS

31

00:02:35,900 --> 00:02:37,666

Next we try

32

00:02:38,200 --> 00:02:40,966

First press the power button

33

00:02:42,333 --> 00:02:46,400

Then quickly press these suspected enter BIOS buttons

34

00:02:46,833 --> 00:02:49,133

It is now in the BIOS

35

00:02:49,733 --> 00:02:55,900

This is the BIOS of this mainboard, it is a pure English interface

36

00:02:57,300 --> 00:03:12,033

Next, let's learn some basic operations of the BIOS and how to find the startup items in the BIOS

37

00:03:15,300 --> 00:03:19,333

After entering the BIOS, we need to change the startup item,

38

00:03:19,833 --> 00:03:24,866

we only need to grab the keyword of the startup item, BOOT or start

39

00:03:25,533 --> 00:03:29,933

As long as we find these two keywords, we will find the adjustment position of the startup item

40

00:03:36,000 --> 00:03:39,733

In this BIOS, the startup items are adjusted here.

41

00:03:44,466 --> 00:03:48,166

Next, let's enter the BIOS startup item to take a look.

42

00:03:48,933 --> 00:03:51,500

Switch to BOOT option via keyboard

43

00:03:52,400 --> 00:03:56,200

The startup item needs to be adjusted under this BOOT

44

00:03:56,566 --> 00:04:00,733

As you can see, there are many adjustable options under BOOT

45

00:04:01,133 --> 00:04:06,100

But we only need to adjust the following startup options

46

00:04:07,966 --> 00:04:11,200

These startup options are the startup sequence

47

00:04:12,000 --> 00:04:15,733

The first one is the original Windows system installed on the computer.

48

00:04:15,766 --> 00:04:18,333

The second is the U disk

49

00:04:18,333 --> 00:04:20,200

The third is also a U disk

50

00:04:20,733 --> 00:04:23,300

Let's take a closer look at these two U disks

51

00:04:23,466 --> 00:04:29,100

As you can see, one is with UEFI in front and the other is without UEFI

52

00:04:29,566 --> 00:04:35,466

What does it represent with UEFI and without UEFI? let's take a look

53

00:04:36,000 --> 00:04:42,866

Under normal circumstances, if there is UEFI in front of the startup item, it means that it is started by UEFI.

54

00:04:43,166 --> 00:04:47,333

If it does not have UEFI, it means that it is started by Legcay.

55

00:04:47,866 --> 00:04:52,366

Under normal circumstances, if the mainboard supports UEFI,

56

00:04:52,566 --> 00:04:55,533

we will use the UEFI boot method

57

00:04:56,000 --> 00:05:00,333

The boot mode of UEFI corresponds to the disk format of GUID,

58

00:05:00,700 --> 00:05:04,300

and the boot mode of Legcay corresponds to the disk format of MBR

59

00:05:04,366 --> 00:05:08,333

This is very important in the following PE sub-disk

60

00:05:09,533 --> 00:05:12,933

Further down, here are some shortcut keys commonly used by BIOS

61

00:05:13,300 --> 00:05:16,300

The most commonly used of these is the F10

62

00:05:16,500 --> 00:05:19,766

F10 is to save and exit the BIOS

63

00:05:21,166 --> 00:05:22,900

Another one is F9

64

00:05:22,900 --> 00:05:25,566

F9 is to restore default settings

65

00:05:25,933 --> 00:05:30,900

With these two shortcut keys, we can modify the BIOS at will

66

00:05:31,466 --> 00:05:35,800

After modification, press F10 to save and exit BIOS

67

00:05:37,900 --> 00:05:42,066

If it is not changed, we can enter the BIOS to modify

68

00:05:42,300 --> 00:05:48,333

If the modification cannot come back, we can use F9 to restore the default settings and return to the original state

69

00:05:51,466 --> 00:05:57,500

In addition to these two shortcut keys, there are two more commonly used shortcut keys, ESC and Enter

70

00:05:58,500 --> 00:06:02,666

ESC is to return to the previous level, or exit the BIOS

71

00:06:03,066 --> 00:06:09,533

When we enter a certain sub-option, we can press ESC to return to the previous level

72

00:06:10,133 --> 00:06:16,033

If you want to modify an option, you can use the Enter key to modify its options

73

00:06:17,366 --> 00:06:21,900

It should be noted here that the shortcut keys of different BIOS may be different.

74

00:06:22,166 --> 00:06:26,766

But they are usually displayed in the lower right corner of the BIOS,

75

00:06:27,300 --> 00:06:30,733

or at the bottom, we just need to pay attention to observe

76

00:06:33,533 --> 00:06:35,900

Next, let's modify the BIOS

77

00:06:39,466 --> 00:06:44,533

As you can see, the first startup item is the Windows system of the hard disk

78

00:06:44,733 --> 00:06:47,000

We want to change it to the PE of the U disk

79

00:06:47,300 --> 00:06:49,333

Press enter

80

00:06:49,800 --> 00:06:52,866

Select it, then select the UEFI bootable PE disk

81

00:06:53,766 --> 00:06:56,500

Then press F10, save and exit

82

00:06:56,800 --> 00:06:59,166

Press enter

83

00:06:59,500 --> 00:07:02,266

At this time, the computer will automatically restart

84

00:07:02,566 --> 00:07:06,666

After restarting, it will enter the PE of the U disk

85

00:07:14,266 --> 00:07:17,966

Ok, now it has entered the PE of the U disk

86

00:07:18,466 --> 00:07:21,933

There are several software in PE that we need to pay attention to

87

00:07:22,266 --> 00:07:26,566

One is the partition wizard with this yellow icon

88

00:07:26,966 --> 00:07:32,066

It can partition the hard disk and modify the disk format

89

00:07:33,800 --> 00:07:36,866

There is also the above Windows installation tool

90

00:07:37,000 --> 00:07:41,933

We can use this Windows installation tool to operate the Windows system

91

00:07:43,666 --> 00:07:47,333

Let's take a look at how to use this partition tool

92

00:07:47,800 --> 00:07:54,300

Partition tool can be used to partition the hard disk and modify the partition table type

93

00:07:55,166 --> 00:08:01,700

In general, if you just reinstall the system, you don't need to partition the disk

94

00:08:02,000 --> 00:08:06,966

If we modify the boot method, or a new computer with a new hard disk,

95

00:08:07,533 --> 00:08:10,600

we need to partition the disk

96

00:08:11,333 --> 00:08:16,866

Before partitioning, pay attention to the partition table type of the disk

97

00:08:17,400 --> 00:08:23,200

UEFI corresponds to the GUID format, and Legcay corresponds to the MBR format

98

00:08:23,300 --> 00:08:25,733

There must be a one-to-one correspondence

99

00:08:25,933 --> 00:08:30,966

If you choose the wrong one, it may cause the system installation to fail

100

00:08:33,666 --> 00:08:41,733

If we want to modify this partition table type, we can click the disk above during partitioning

101

00:08:42,100 --> 00:08:44,733

Then there are two options below

102

00:08:44,733 --> 00:08:48,466

One is to change the partition table type to GUID,

103

00:08:48,700 --> 00:08:52,166

and the other is to change the partition table type to MBR

104

00:08:52,933 --> 00:08:57,366

The gray one represents its current state

105

00:08:57,666 --> 00:09:03,366

This means that the hard drive is in GUID state.

106

00:09:03,900 --> 00:09:11,500

After modification, click Save Changes to complete the modification of the partition table type

107

00:09:12,266 --> 00:09:16,733

After modifying the partition table, we also need to partition the disk

108

00:09:16,966 --> 00:09:21,800

Of course, if you reinstall the system, you can skip this step directly.

109

00:09:22,300 --> 00:09:28,000

When partitioning the disk, click Quick Partition in Partition Wizard

110

00:09:28,700 --> 00:09:32,766

This is the interface that pops up after clicking the quick partition

111

00:09:33,066 --> 00:09:36,866

There are not many options for us to choose.

112

00:09:37,566 --> 00:09:41,966

First we need to select the partition table type

113

00:09:42,166 --> 00:09:46,400

Under normal circumstances, this partition table type will be automatically selected

114

00:09:46,600 --> 00:09:54,566

Here is also to remind us whether the type of partition table is now is the type of partition table we want

115

00:09:55,133 --> 00:10:02,966

If we choose the partition table type of GUID, we must create ESP partition and MSR partition

116

00:10:04,600 --> 00:10:09,733

ESP partition and MSR partition are two very important partitions

117

00:10:10,100 --> 00:10:15,066

Without these two partitions, the system will definitely not be installed.

118

00:10:16,366 --> 00:10:19,000

Next we have to choose the number of partitions

119

00:10:19,166 --> 00:10:23,766

According to the desired number of partitions, you can select the corresponding number of partitions

120

00:10:24,433 --> 00:10:27,500

You can adjust the size of each partition on the right

121

00:10:27,800 --> 00:10:31,866

Under normal circumstances, the c disk should be divided into at least 100G

122

00:10:32,733 --> 00:10:38,733

After selecting these, we choose the 2048 sector

123

00:10:40,966 --> 00:10:43,600

This is usually checked by default.

124

00:10:43,900 --> 00:10:47,133

It is what we usually call 4K alignment

125

00:10:47,700 --> 00:10:53,300

If the hard disk is not 4K aligned, it will not only slow down the speed of the hard disk,

126

00:10:53,600 --> 00:10:56,700

but also damage the life of the hard disk

127

00:10:57,333 --> 00:11:03,500

After selecting these, click OK to complete the partitioning of the disk

128

00:11:04,400 --> 00:11:06,966

Next let's try

129

00:11:08,700 --> 00:11:13,866

We switch to PE, open the partition tool

130

00:11:19,066 --> 00:11:24,733

It can be seen that there is a system in the hard disk installed in the computer.

131

00:11:25,000 --> 00:11:32,266

There are two disks here, one is the PE disk, and the other is the hard disk installed on the computer.

132

00:11:32,700 --> 00:11:38,866

If you can't tell the difference, if you are afraid of the wrong disk, you can unplug the PE disk first.

133

00:11:41,133 --> 00:11:48,666

After unplugging, there is only one disk left, which is the disk we want to install the system on

134

00:11:49,066 --> 00:11:53,900

The disk already has a partition, we restore it to an unpartitioned state

135

00:11:54,333 --> 00:11:56,466

Start all over again

136

00:12:00,500 --> 00:12:05,933

If we installed a new hard disk, then the state of the hard disk should be the same as the current one,

137

00:12:06,400 --> 00:12:09,933

without any partition

138

00:12:10,166 --> 00:12:14,100

Let's first see if its partition table type is what we need

139

00:12:14,500 --> 00:12:20,766

Just now we used the UEFI boot method, so the partition table type here is GPT

140

00:12:22,000 --> 00:12:25,566

GPT is GUID, these two are the same

141

00:12:25,800 --> 00:12:33,700

If the partition table type here is incorrect, click the disk here to modify the partition table type

142

00:12:34,733 --> 00:12:37,900

We're going to change it to a GUID

143

00:12:39,600 --> 00:12:46,300

After the modification, click Save Changes to modify the partition table type of the disk.

144

00:12:46,800 --> 00:12:51,400

After modifying the partition table type, we need to partition the disk

145

00:12:51,933 --> 00:12:58,466

Because this hard disk is 120G, we only need to divide it into a c drive.

146

00:12:58,866 --> 00:13:03,800

We select this hard disk and click on the quick partition above

147

00:13:05,166 --> 00:13:08,066

There is no problem with the partition table type GUID

148

00:13:08,133 --> 00:13:10,766

Create ESP partition and create MSR partition

149

00:13:11,666 --> 00:13:14,133

It has been checked by default, and there is no problem.

150

00:13:14,666 --> 00:13:17,333

Then the number of partitions we choose a partition

151

00:13:19,200 --> 00:13:22,200

4K alignment is also checked by default

152

00:13:22,933 --> 00:13:24,800

Click OK

153

00:13:28,700 --> 00:13:30,900

In this way, the partition has been completed

154

00:13:30,966 --> 00:13:33,233

As you can see, there are currently three partitions under this disk,

155

00:13:33,500 --> 00:13:34,833

ESP partition, MSR partition and c drive

156

00:13:42,466 --> 00:13:51,300

After the partition is completed, we can install the system, we need to use the Windows installer

157

00:13:53,300 --> 00:13:57,666

Next, let me tell you how to use the Windows installer

158

00:13:58,733 --> 00:14:04,133

In the Windows installer, there are not many options for us to choose

159

00:14:04,800 --> 00:14:12,100

After opening the Windows installer, the first thing to choose is the location of the ISO image

160

00:14:12,300 --> 00:14:18,133

That is, the system image we put on the PE disk in advance

161

00:14:22,566 --> 00:14:27,666

The second box selects the boot drive

162

00:14:27,700 --> 00:14:35,533

If we are using the GPT partition, choose the ESP partition

163

00:14:35,800 --> 00:14:42,533

If we are using the MBR partition, we must choose the c drive

164

00:14:44,200 --> 00:14:47,000

The third, the location of the installation disk

165

00:14:47,266 --> 00:14:51,700

The location of the installation disk is the c drive after the system is installed

166

00:14:51,733 --> 00:14:55,400

We can choose the C drive

167

00:14:56,400 --> 00:15:03,100

If you are reinstalling the system, you must pay attention to whether the c drive in the PE is the c drive in the system

168

00:15:03,466 --> 00:15:07,966

Because the drive letters may be messed up in PE

169

00:15:08,266 --> 00:15:11,966

If the drive letters are messed up, there may be a wrong drive

170

00:15:12,166 --> 00:15:15,300

So when choosing the location of the installation disk,

171

00:15:15,400 --> 00:15:18,400

be sure to pay attention to whether you choose the c drive or not.

172

00:15:20,333 --> 00:15:24,600

After selecting these three options, we choose the version

173

00:15:24,900 --> 00:15:28,333

After selecting the version, you can click to start the installation

174

00:15:29,500 --> 00:15:32,166

Next, let's try it in PE

175

00:15:34,300 --> 00:15:37,733

We first select the location of the ISO image

176

00:15:38,100 --> 00:15:42,466

Click to search this computer

177

00:15:42,566 --> 00:15:47,133

We unplugged the PE disk just now, and we plug in the PE disk again

178

00:15:50,500 --> 00:15:56,333

After the PE disk is plugged in, click Search This Computer to find the PE disk

179

00:15:56,533 --> 00:16:02,200

Find the WIN10 image we downloaded in advance, click to open

180

00:16:02,533 --> 00:16:04,966

Then the first selection is done

181

00:16:05,300 --> 00:16:10,066

Second, we need to select the ESP partition that was partitioned before

182

00:16:10,733 --> 00:16:15,233

Under normal circumstances, the second option will automatically help us choose

183

00:16:15,733 --> 00:16:20,433

But sometimes it also chooses wrong, we have to watch carefully

184

00:16:20,666 --> 00:16:29,200

Click the arrow here to see that it selects the first partition of the 120G disk, so there is nothing wrong

185

00:16:30,700 --> 00:16:33,300

The third, the location where the disk drive is installed

186

00:16:33,400 --> 00:16:37,700

Just select the c drive of this 120G disk

187

00:16:38,333 --> 00:16:41,933

Next select the version of the system

188

00:16:42,600 --> 00:16:49,366

In general, we recommend the professional version for desktops and the home version for notebooks

189

00:16:49,500 --> 00:16:54,933

This is desktop so we click on pro and then install

190

00:16:55,400 --> 00:17:04,133

An interface will pop up here, we can choose nothing in this interface, just click OK

191

00:17:04,833 --> 00:17:09,566

Then it will go through a progress bar

192

00:17:11,266 --> 00:17:13,666

Let's fast forward a little bit

193

00:17:23,933 --> 00:17:28,466

When the progress bar is finished, it will automatically pop up a pop-up window

194

00:17:28,666 --> 00:17:31,366

We just click restart

195

00:17:32,533 --> 00:17:38,700

At this time, we need to unplug the PE disk to ensure that the computer will start from the local hard disk

196

00:17:39,466 --> 00:17:45,300

After starting, it will enter the second stage of the installation process

197

00:17:45,500 --> 00:17:51,566

In this process, we don't need to do anything, just wait patiently

198

00:17:52,100 --> 00:17:56,466

During this process, the computer may restart several times

199

00:18:01,866 --> 00:18:05,366

Next, we need to perform a series of settings on the computer

200

00:18:05,533 --> 00:18:11,766

These settings are not important, we can choose according to our own preferences

201

00:18:12,600 --> 00:18:16,300

After the setup is complete, we need to wait for a while

202

00:18:16,533 --> 00:18:20,100

Then you will enter the Windows desktop

203

00:18:24,466 --> 00:18:30,333

Well, so far the system has been installed, but it has not been fully installed

204

00:18:31,166 --> 00:18:34,533

Next, we need to perform a series of optimization operations

205

00:18:34,733 --> 00:18:38,366

Let's talk about the two most basic optimization operations here,

206

00:18:39,466 --> 00:18:42,933

that is, call out this computer and install the driver.

207

00:18:43,766 --> 00:18:49,000

To bring up this computer, you need to select the theme in the personalization of the right mouse button

208

00:18:49,133 --> 00:18:53,700

Then check the box on the computer in the desktop icon settings

209

00:18:53,900 --> 00:18:58,300

To install the driver, we need to use the driver package we downloaded in advance

210

00:18:59,066 --> 00:19:00,800

Next let's try

211

00:19:03,866 --> 00:19:11,800

First, right-click on the desktop, click Personalize, and select Theme

212

00:19:13,333 --> 00:19:18,400

Select Desktop Icon Settings, check Computer, and click OK

213

00:19:18,800 --> 00:19:21,533

In this way, the computer desktop has this computer

214

00:19:22,500 --> 00:19:27,766

When we open this computer, we can see the c drive

215

00:19:28,000 --> 00:19:37,700

We plug in the PE disk, open the PE disk, and open the driver package we downloaded in advance

216

00:19:40,966 --> 00:19:43,666

Run the software in the driver package

217

00:19:49,933 --> 00:19:58,266

Next, the driver package will complete the driver installation

218

00:20:06,200 --> 00:20:11,500

After the driver installation is complete, let's see if all the drivers are installed

219

00:20:11,800 --> 00:20:16,533

Right-click on the Windows logo and click on Device Manager

220

00:20:17,266 --> 00:20:22,933

If you open the device manager and see this interface, it means that all the drivers are installed.

221

00:20:23,300 --> 00:20:26,900

If there is a yellow exclamation mark in front of some devices,

222

00:20:27,333 --> 00:20:29,900

it means that some drivers have not been installed

223

00:20:30,100 --> 00:20:33,166

It may be necessary to connect to the Internet and run the driver again

224

00:20:33,766 --> 00:20:41,233

After the driver is finished, activate the system to complete the installation of the entire system

225

00:20:41,933 --> 00:20:45,066

We will not talk about the activation of the system here

226

00:20:45,533 --> 00:20:50,133

So far, the installation of Windows is completely completed.
