Win7 system before installing, you must know the thing

After you have downloaded the ISO image file, burn the DVD, and then choose to run the installer. The difference in the performance of the installer in Windows depends on which way you install it, if your system already has XP, Vista, or earlier versions, you can start the installer from the Windows operating system. Alternatively, you can boot the system from the installation media. Either way, you'll see a dialog box.

First, choose a good installation method

What's the difference? If you run Setup in Windows.

1, you cannot run the 64-bit installer in x86 version of Windows.

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

3, must use the existing partition, cannot change, the installation program also does not acknowledge unallocated space.

If you are booting from a Windows 7 DVD:

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

2. You can delete existing partitions, create new partitions, extend existing partitions, or designate an unallocated space as the installation location.

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

In addition, if you start Setup in Windows, you can choose to run the compatibility check on an existing system.

Second, how to install the new

If you plan to do a clean installation, it is recommended that you back up and then start the installer from Windows 7 DVD to eliminate any existing partitions. Because it will save you time and reduce some of the trouble. Now, suppose you have made a backup. Because all of the data will disappear, so be sure to save it before you start.

There are four steps to a new installation:

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

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

3, select a section from the list, and then click Delete

4. Repeat for any additional volume until there is nothing left but unallocated space.

You can now use all unallocated space on the drive to complete the installation.

Third, find the old driver don't be afraid

In my tests, so far, Windows 7 has done a very thorough drive. But it is not perfect, some devices appear blank, or be replaced by the general driver.

If you have already installed a previous version of Windows Vista or Windows 7, you do not need to use a special program backup driver from the old system. Windows Vista and Windows7 in a folder called Filerepository, the Web page teaching network reminds you to save all the driver's local copies, which are in subfolders 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 be over 1GB.

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

Four, no fear to overwrite the old folder

When you instruct Windows Installer to make a custom installation, it moves the old Windows,program Files, and the user folders (Documents and Settings) to a named Windows. Old folder. A new installation creates a new top-level folder on the current system drive: Windows,program files and users. The advantage of this is that it is obvious that a single disk on a system has a new installation and no data loss if it has only one partition and a large amount of free disk space. A new, non-destructive installation gives you a fresh start, and the old data files are securely hidden in Windows. Old folder.

To perform a clean and non-destructive installation, you can start Windows 7 Setup from Windows 7 DVD, click the installation steps, select the Customization (Advanced) option, and then, in the list of available disk partitions, select a partition that contains your current Windows installation. For most people, it is drive C, click OK, you will see a warning dialog box, after you finish setting up, when you first start Windows 7, you will see all your data and program files in Windows. Old folder. If you have any old data files that need to be recovered, you can find them in the Users folder (Windows Vista) or the documents and settings.

Five, hard disk capacity requirements to be innocence

Under the current standards, you don't need a lot of disk space to install Windows 7. Microsoft released the RC minimum hardware recommended 16G of free disk space. But that's not a mandatory requirement, I still have 3.95G of available disk space after installing Windows 7 ultimate on a virtual machine in a 10G drive (9.9G format).

After the small series see, fully installed Windows 7 Ultimate x86 requires 6 to 9G of space. Obviously, this amount will increase when you install additional programs or create data files. But how big is the system partition? To remind you that 15G is a minimal metric, but sooner or later it will become tense, so if you have enough spare disk space, it is recommended to reserve at least 30GB.
