00:00:00,300 --> 00:00:03,633

In this lesson we will talk about some common problems encountered in the process

2

00:00:03,633 --> 00:00:05,333

of installing the Windows system

3

00:00:07,766 --> 00:00:12,066

The first one, the hard disk is not recognized in PE

4

00:00:13,133 --> 00:00:17,433

Its failure phenomenon is that the hard disk is good, and the computer is also good,

5

00:00:17,633 --> 00:00:19,866

but the hard disk cannot be recognized in PE.

6

00:00:22,933 --> 00:00:26,600

Even if you don't enter PE, it can enter the system by itself

7

00:00:27,066 --> 00:00:31,733

There are two possibilities for this kind of problem, one is relatively rare and the other is more common

8

00:00:32,166 --> 00:00:37,033

The relatively rare one is that there is a problem with the BIOS settings,

9

00:00:37,366 --> 00:00:40,500

which causes the hard disk to not be recognized in the PE.

10

00:00:43,200 --> 00:00:49,733

It may be that we accidentally adjusted the BIOS settings wrongly during the process of modifying the startup items,

11

00:00:49,966 --> 00:00:51,833

which caused this failure

12

00:00:52,700 --> 00:00:59,133

First of all, we need to confirm whether the hard disk format in the BIOS is AHCI

13

00:00:59,866 --> 00:01:07,100

There are three common hard disk formats at present, AHCI, RIAD and IDE

14

00:01:08,333 --> 00:01:13,533

In general, 99% of computers use the AHCI format

15

00:01:13,866 --> 00:01:21,633

If we find that the format of the hard disk is not AHC in the BIOS, we can try to change it to AHCI

16

00:01:23,066 --> 00:01:26,100

Of course, if the customer's computer is set up with RIAD,

17

00:01:26,100 --> 00:01:29,266

then the hard disk format is not recommended to be modified casually.

18

00:01:30,866 --> 00:01:35,966

Second, turn on or off the CSM module to try

19

00:01:36,533 --> 00:01:39,466

The CSM module is a compatibility module.

20

00:01:39,666 --> 00:01:44,500

Some computers can support Legcay startup after opening this module.

21

00:01:44,500 --> 00:01:48,600

Of course not all computers have a CSM module

22

00:01:49,200 --> 00:01:58,466

After the CSM module is modified, it may cause the hard disk not to be recognized in the PE

23

00:01:58,666 --> 00:02:04,166

So we can try to open or close the CSM module to try

24

00:02:04,166 --> 00:02:12,200

CSM modules and startup items are adjusted under an option

25

00:02:14,966 --> 00:02:20,300

Further down, it is possible that we made a mistake in the process of adjusting the startup items

26

00:02:20,466 --> 00:02:22,866

and closed some hard disk ports.

27

00:02:23,866 --> 00:02:28,033

Like this possibility, if we are not particularly familiar with the BIOS,

28

00:02:28,300 --> 00:02:31,600

we can directly try to restore the default settings

29

00:02:31,666 --> 00:02:34,600

That is, press the F9 shortcut key in the BIOS

30

00:02:35,566 --> 00:02:41,166

In this case, the default settings will be restored directly to see if this problem can be solved.

31

00:02:41,566 --> 00:02:47,833

Of course, we can also ignore the above operations and restore the default settings directly in the BIOS

32

00:02:48,933 --> 00:02:52,133

In general, this problem can be solved by

33

00:02:53,066 --> 00:02:59,133

Next, let's look at another common reason, that is, PE does not support

34

00:02:59,966 --> 00:03:05,733

Intel uses a new technology, VMD technology, in the 11th generation CPU and later

35

00:03:06,466 --> 00:03:09,200

VMD technology needs to be driven

36

00:03:09,533 --> 00:03:14,966

If the driver of VMD technology is not installed, it will lead to failure to recognize the hard disk

37

00:03:15,500 --> 00:03:20,766

In general, the complete system has built-in VMD driver

38

00:03:21,166 --> 00:03:25,966

However, some old PEs may not have this driver built in,

39

00:03:26,100 --> 00:03:30,933

which will cause the hard disk not to be recognized in PE.

40

00:03:31,966 --> 00:03:35,766

To solve this problem is also very simple

41

00:03:36,133 --> 00:03:43,933

The easiest, most recommended and once-and-for-all method is to use the latest version of PE.

42

00:03:43,966 --> 00:03:49,600

Abandoning the old PE and using the latest version of PE can perfectly solve this problem

43

00:03:50,900 --> 00:03:54,466

Next, let's take a look at the error reported by the installation system

44

00:03:55,266 --> 00:03:58,433

The error reported during the installation system is divided into two types,

45

00:03:58,433 --> 00:04:01,133

one is to report an error when installing in PE,

46

00:04:01,433 --> 00:04:06,733

and the other is to report an error when the computer starts the second stage of installation.

47

00:04:07,466 --> 00:04:11,066

First look at the installation error in PE

48

00:04:11,633 --> 00:04:16,633

When we use the Windows installer to start to enter the progress bar,

49

00:04:16,633 --> 00:04:22,100

it may report such an error, showing that the application system image failed

50

00:04:22,700 --> 00:04:26,000

This error may be caused by the failure to format the c drive,

51

00:04:26,000 --> 00:04:33,566

or it may be caused by the inconsistency between the boot method and the partition table type of the hard disk.

52

00:04:34,066 --> 00:04:40,533

If you encounter this error, you can try to manually format the c drive

53

00:04:41,333 --> 00:04:48,600

If it still doesn't work, we need to confirm whether the current boot mode matches the format of the hard disk.

54

00:04:48,966 --> 00:04:54,400

That is what we said before Legcay corresponds to MBR, UEFI corresponds to GPT

55

00:04:54,966 --> 00:04:58,333

If something goes wrong here, it may also cause this failure

56

00:04:59,066 --> 00:05:04,800

The last one is a relatively rare situation, that is, the image file is really damaged

57

00:05:05,266 --> 00:05:08,600

We can try to replace a mirror file to try

58

00:05:10,066 --> 00:05:13,400

Next, let's look at the installation completed in PE,

59

00:05:13,466 --> 00:05:18,000

and the installation error in the second stage after the computer restarts

60

00:05:18,666 --> 00:05:23,766

After the computer restarts, it will automatically perform the second stage of the installation

61

00:05:24,433 --> 00:05:27,366

In this state, there is generally no need for us to operate

62

00:05:27,766 --> 00:05:32,433

However, the computer may report such an error in the middle of the installation,

63

00:05:32,766 --> 00:05:37,000

indicating that it restarted unexpectedly or encountered an error.

64

00:05:38,300 --> 00:05:40,900

There are many possible reasons for this failure

65

00:05:41,133 --> 00:05:45,966

There may be a problem with the system image, or there may be a problem with the hardware

66

00:05:47,566 --> 00:05:52,600

So when you encounter this error, don't install the system on this computer.

67

00:05:53,533 --> 00:05:58,500

You can unplug the hard drive and plug it into another computer

68

00:05:58,733 --> 00:06:02,666

Use another computer to install the system on this hard disk

69

00:06:02,900 --> 00:06:07,566

After the installation is complete, unplug the hard drive and plug it back into the computer.

70

00:06:08,300 --> 00:06:10,933

Try to see if there are any other problems

71

00:06:11,500 --> 00:06:17,100

Well, the above are the problems we often encounter in the process of installing the system

72

00:06:18,133 --> 00:06:24,133

After we have learned to solve these problems, the course of Windows installation is completely over
