SUMMARY

This article describes how to use the Windows 2000 Professional Setup CD-ROM to perform an in-place upgrade over the existing installation, if you have first performed the emergency repair process and the computer still does not operate normally.

MORE INFORMATION

This procedure is a last resort before reinstalling the operating system. Note that the time required to complete the following procedure is equal to the time that it takes to reinstall the operating system.

To perform an in-place upgrade of Windows 2000, follow these steps:
  1. Insert the Windows 2000 Setup CD into the CD-ROM drive, start the computer, and then press a key to start from the CD-ROM.
  2. On the Windows 2000 Setup screen, press ENTER to run the To set up Windows 2000 now, press Enter command.
  3. Press the F8 key to accept the License Agreement.
  4. Setup should now detect your installation.

    Note If the Setup program does not detect a previous installation but just continues to the partitioning screen, there is a problem. An in-place upgrade may not be possible.
  5. When you are prompted to repair the existing Windows 2000 installation, press R. Windows 2000 Setup performs an in-place upgrade of the existing installation. Note that you might lose some of your customized settings for the system files.
