Install Win7 system, you must know the installation common sense

Although installing Win7 system is an easy task, it is necessary to familiarize yourself with the detailed key points of installing Win7 system. It can help you fully understand Win7 system. What should you pay attention to when installing? Let's talk about it together.

First, pre-installation considerations

To distinguish between running the installer in Windows or booting from Windows 7 DVD.

If you are running the installer on Windows, you need to pay attention:

1. You cannot run the 64-bit installer on Windows running x86.

2, install Windows 7 and the existing Windows version of the same volume.

3, must use the existing partition, can not be changed, the installer does not recognize the unallocated space.

If it is

Boot from Windows 7 DVD:

1. You cannot upgrade an existing Windows version, you can only customize the installation.

2, you can delete an existing partition, create a new partition, extend an existing disk partition, or specify an unallocated space as the installation location.

3, install Windows 7 and the existing Windows version of the same volume.

If you launch the installer in Windows, you can choose to run a compatibility check on your existing system.

Second, how to create a clean installation environment

Want to have a clean installation system environment, you need to back up at this time, then boot the installer from the Windows 7 DVD, eliminate any existing Partition. If you don't have a backup, all the data will disappear, so be sure to save it before you start.

The steps are as follows:

1. Start the program from the Windows DVD, follow the prompts to select a custom (advanced) installation, and then click Next to enter the screen;

2 Click Drive Options (Advanced) to display all available disk management tools;

3. Select a partition from the list and click Delete

4. Repeat for any additional volumes. Until nothing was left except for the unallocated space.

Now you can complete the installation with all the unallocated space on the drive.

Third, use the old driver to install

If you have installed an earlier version of Windows Vista or Windows 7, you do not need to use a special program to backup the driver from the old system. Windows Vista and Windows 7 are in a folder called FileRepository, which reminds everyone to save a local copy of all drivers, which is in a subfolder of the DriverStore folder. The full path is C:WindowsSystem32DriverStoreFileRepository.

In a clean Windows 7 X86 installation, the FileRepository folder contains more than 900 MB of files. If you add some new devices or updates, this number can easily exceed 1GB.

After you complete the new installation of Windows 7, you can use Device Manager to install or update any driver, or Just click on the old driver you saved to install it.

Four, no fear to overwrite old folders

When you instruct Windows Installer to do a custom installation, it will use the old Windows, Program Files, and User Folders (Documents and Settings) Move to a folder called Windows. Old. The new installation creates a new set of top-level folders on the current system drive: Windows, Program Files, and Users. The benefit of this is that the single disk on the system has a new installation with only one partition and a large amount of free disk space. And no data will be lost. A new, non-destructive installation gives you a new start, and old data files are safely hidden in the Windows.old folder.

To perform a clean and non-destructive installation, you can launch the Windows 7 installer on Windows or from the Windows 7 DVD, click on the installation steps, select the Custom (Advanced) option, and then, in the list of available disk partitions, Choose a partition that contains your current Windows installation. For most people, it's drive C. After you click OK, you'll see a warning dialog. After you've finished setting up, when you first start Windows 7, you'll see all your data and program files. In the Windows. Old folder. If you have any old data files to retrieve, you can find them in the Users folder (Windows Vista) or Documents and Settings.

V. Hard disk capacity requirements return to the original

Under the current standard, you do not need a lot of disk space to install Windows 7. Microsoft announced the RC minimum hardware recommended 16G free disk space. But that's not a hard requirement. After installing Windows 7 Ultimate on a 10G drive (9.9G format) virtual machine, I still have 3.95G of free disk space.

If you know all of the above, I believe that any problems encountered during the installation of Win7 system will no longer bother you, and your system will be installed in a safe environment. Pay attention to the installation of small details to achieve the overall effect.
