Five things to know before Win7 installation (2)

        Third, without fear of overwriting the old file folders

When you instruct Windows Setup to do a custom installation, it will be the old Windows, ProgramFiles, and user folders (DocumentsandSettings) to move to a named Windows. Old folder. The new installation creates a new set of top-level folders on the current system drive: Windows, ProgramFiles, and Users.

the benefits of doing so is obvious to make a single disk on the system only one partition and plenty of free disk space, get a new installation without losing any data. 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 installation of non-destructive, you can step to start or Windows7 Windows installer from Windows7DVD, click install, choose Custom (Advanced) option, and then, in the list of available disk partition, select contains a The partition of your current Windows installation. For most people, it is drive C. After

click OK, you'll see a warning dialog box. After

complete the setup, when you first start Windows7, you will see all of your data and program files folder in Windows.Old file. If you have any old data files to retrieve, you can find them in Usersfolder (WindowsVista) or DocumentsandSettings.

Fourth, do not be afraid to get back the old drive

in my tests so far, Windows7 on the drive has been very thorough. But it's not perfect, some devices are blank, or replaced by generic drivers.

If you have an earlier version of WindowsVista or Windows7 installation, you do not need a backup driver uses a special program from the old system. Windows Vista and Windows 7 save a local copy of all drivers in a folder called FileRepository, which is in a subfolder of the DriverStore folder. The full path is C:WindowsSystem32DriverStoreFileRepository.

in a clean Windows7X86 installation, FileRepository folder contains more than 900 MB file. If you add some new devices or updates, this number can easily exceed 1GB.

After you complete a new installation of Windows7, you can use the Device Manager to install or update any driver, or just click your old drivers saved the installation.

5, how to install a new

If you plan to do a clean install, it is recommended that you back up, and then start the installation program from Windows7DVD, remove any existing partitions. Because this will save you time and reduce some trouble. Now assume that you have already made a backup. Because all the data will disappear, so be sure to save it before you start.

a new installation, a total of four steps:

1, from WindowsDVD start the program, follow the prompts to choose a Custom (advanced) installation, and then click Next to enter the picture;

2, click drive options (advanced) to display all the available disk management tools;

3, a partition selected from the list, then click delete;

4, for any other The extra volume is repeated until nothing is left except for the unallocated space.

Now, you can use all unallocated space on the drive to complete the installation.
