Windows 7 installation failure reason resolution

I believe that so far, many users have installed and used some versions of Windows 7 RTM. From the perspective of the average user, you should see that Windows 7 is different from the previous system in installation. Among them, there are several changes that are very obvious and require everyone to understand and pay attention. 1. Give the user a 30-day buffer period. When installing Windows 7, you should enter the serial number as usual, but it is in the final stage of installation. At this point, you can enter the authorized serial number. Of course, our Windows 7 installer will also prompt the user to enter the serial number at this moment, as long as the serial number is added within 30 days of the normal operation of the system. In fact, this feature is also available in Vista, but many people may not know. In fact, such a strategy is very beneficial to the user. Because, sometimes, we are anxious to install Windows 7 system for some applications, and there is no serial number at hand, this strategy gives users a 30-day buffer period, allowing users to install the system and ensure its normal use, then Carefully add the serial number and activate it. 2. Make the system more secure and reliable hidden partition If the bare machine is newly installed Windows 7, or use the partition tool that comes with the installer to re-partition during installation, you will find a mysterious hidden in the disk manager after the installation is completed. Partitions, such partitions are not available in previous system installations. This hidden partition has puzzled many users, and there are many ways to delete or avoid the hidden partition in the forum. However, this hidden partition is usually unavoidable and cannot be deleted under normal circumstances. If the user uses a third-party tool to force the deletion of the hidden partition, the system will fail to start without exception. In fact, many users do this because they don't understand this hidden partition and don't know its role. The author below analyzes this hidden partition. The first thing to say is that the size of this hidden partition is different in each version of Windows 7. In the bate version of Windows 7, the hidden partition is 200M. From the RC version of Windows 7 and later versions, the hidden partition size is changed to 100MB, but in any case, the effect is the same. During the Windows 7 installation process, it will first create a hidden partition of about 100M at the beginning of the disk, and then install Windows 7 in another partition. The advantages of this are: (1). When we enabled Bit-Locker in Windows 7 or when recovering from the system, this partition mode provides us with convenience and security. Because Bit-Locker and system recovery will not operate on the partition, the system boot file saved in it will be protected from damage to ensure the normal boot of the computer. (2). The isolation of the system boot file and the system file is realized, and the avoided party is destroyed and the fish is caught. Usually, we are used to the system to install the entire Windows in the C drive. In fact, the boot process of Windows is technically divided into two steps: Windows System partition and Boot partition. The System partition saves the startup files necessary for Windows startup, such as the boot sector (mbr), the corresponding boot files, third-party drivers such as RID hard disk support, and so on. The so-called Boot partition is actually what we usually call C:, which contains most of the files needed for Windows to run. So, the Windows System partition is a relatively small partition, and this hidden partition is the Windows System partition that is isolated from the usual system partition. (3). Another advantage is obvious: when our system fails, or we have to do a dual system installation, and enable Bit-Locker, save the relevant files in the hidden partition to avoid Modification or destruction of the System partition during the above operations, so that all operations are directed to the Windows Boot partition. Based on the above analysis of the importance and role of this hidden partition, I recommend that you keep the partition when you install Windows 7. After all, it does not take up much space, and it is critical to the security and stability of the system. 3. Dialysis Windows 7 installation CD file Installation of Windows 7 via CD is believed to be the choice of many users. There should be no problem with the system installation, and everyone is also familiar with the road. However, when deploying in an enterprise environment, it is not possible to ship the Windows 7 master disks one by one. Typically, we need to customize the system image (the system configuration has integrated common software) and then distribute the image for bulk deployment. Therefore, it is necessary for the administrator to have a certain understanding of the package of the Windows 7 image and its CD file. In Windows 7, Microsoft uses the WIM format file mapping method, which is different from the ghost we know. This is a file-based image, not a sector-based one. It is characterized by: hardware-independent, hardware-independent; multiple images can be stored in one actual file; it can be installed on any size partition without the same ghost; and it allows administrators to maintain the image offline. Among them, the feature of offline editing of the wim image allows administrators to adjust system settings and software. We browse the installation CD of Windows 7, and you can see many files in the sources directory, where install.win is the installation file of Windows 7, and boot.win is the installation boot file. These two files are the most central system installation files, of course, they also occupy a large amount of CD space. We need to use these two files when doing system image through DISM. In addition, mainly some fonts, pictures, dll files. 4. Analysis of Windows 7 installation failure factors I believe that many users have experienced Windows installation failure. For Windows 7, there are many reasons why the installation cannot continue. In the author's experience, the main reason is nothing more than the incompatibility of hardware components or the hardware configuration of the system can not meet the minimum requirements of Windows 7, so in the troubleshooting should focus on this aspect, less detours. The author below enumerates several of the most typical cases for analysis. (1). The installer refuses to install or start If the hardware components are not compatible with Windows 7, it may cause the installation to fail or the installer to fail to start. So make sure that Windows 7 can detect all system hardware before installation and that it is included in the Windows 7 Hardware Compatibility List (HCL). It is recommended that you perform the necessary compatibility checks before installing Windows 7. If you have already started the installation, it is too late to check compatibility. If it is an upgrade installation or a dual system installation, I can see that I can reboot to the original system, and then start the installation program for detection with the following parameters. “/1394debug:” Enable kernel debugging on specific channels of the Firewire (IEEE 1394) port. “/debug” Enable kernel debugging via the COM1 or COM2 port. “/usbdebug:” Enable kernel debugging by going to the USB port of a specific target device. These options put the installer in debug mode to help determine the cause of the failure. If the installer detects a hardware conflict, you can configure the hardware to eliminate the conflict. (2). The installer reports a media or DVD error If you install directly from the Windows 7 installation CD, or install from the network through a release share, you may also encounter a media error that causes the installation to fail. For the case of installing from a DVD, we can try to clean the DVD drive so that it can read the disk better, or replace the CD-ROM or CD-ROM. For enterprise users, the client generally performs shared installation from the shared release. Generally, the share does not include all the installation files, or there is a problem with the shared network connection. You can debug from these two aspects. (3). The installer reports that the system resources are insufficient. Microsoft recently announced the minimum hardware resource requirements for Windows 7 installation, that is, at least 512MB of memory and about 25GB of hard disk space. For some old machine users, the installer fails to start if the minimum memory requirements for Windows 7 installation are not met. If the installer can start, but it detects that there is not enough disk space, it will not be installed. Unless we rebuild the partition or delete the original partition, we have enough space to install the operating system. For such installation failures, Windows 7 will have a clear error message, and troubleshooting is of course very easy. (4). Suffering from the installation program suddenly stops responding Excluding all the above factors, sometimes we are still experiencing a situation in which the installation program suddenly stops. Normally, the installation of Windows 7 was going smoothly, and suddenly we found that the installation stopped responding and stopped the installation in the current interface without any progress. In this case, sometimes we will see the error prompt of stop, sometimes there is nothing, the system is like a crash. If there is an error message to install stop, but most of the stop errors are some obscure error codes. It does not clearly tell us where something went wrong. At this point, we can take notes of these error numbers or codes, then go to the Microsoft Knowledge Base (click to enter) to find out the detailed information, and then debug. At this point the installation can not be done, we usually need to press Ctrl+Alt+Del to restart the computer to interrupt the error, sometimes press the combination button is invalid. We need to press the power button on the computer to force the system to restart. In general, after we restart the computer, we will go directly to the installer and the installation will continue. In some cases, you may also see the boot menu, and if this is the case, we can select the "Windows Installer" option to allow the installer to proceed. If the installer stops responding again, you will need to restart your computer, and sometimes you may need to try multiple times to complete the installation. Such failures are generally caused by sudden factors, and restarts can solve the problem. However, memory and CPU may also be the source of the problem, which requires us to make more complicated troubleshooting, in general, replacing the hardware will solve the problem. Summary: The above related issues related to Windows 7 installation, I have experienced personally, and others have encountered. Combine and summarize them with your own experience and understanding, and hope to help those who are installing or will install Windows 7.
