Demystifying why the Windows 7 system failed to install

I believe many users have experienced the failure of Windows installation, but many people choose to reinstall without considering the reason for the failure. However, for Windows 7, there are many reasons why the installation cannot continue. As long as the cause is found, the installation will be less problematic. 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 Windows7, 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 (IEEE1394) 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 media or DVD error

If you install directly from the Windows 7 installation CD, or install it from the network through the release share, you may also encounter a media error and cause the installation. The problem of failure. 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). Installer reports insufficient system resources

Microsoft recently announced the minimum hardware resource requirements for Windows 7 installation, namely at least 512MB of memory and approximately 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). Encounter the installation program suddenly stops responding

Excluding all the above factors, sometimes we have to encounter the situation that 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 message 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, and can't tell us exactly where the problem is. 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 installation program 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. After the installation fails, the user should find the reason for the failure of the installation, then pay attention to the improvement, and organize and summarize them with their own experience and understanding. I hope that the friends who are installing or will install Windows7 will be helpful.
