Setup and Startup

After the text-mode phase of Setup is complete, the computer restarts, and the GUI-mode phase of Setup begins. GUI-mode is identified by a graphical user interface (GUI) and the Setup wizard, which begins with the End-User License Agreement ( EULA) and Product ID dialog box.



When you use Winnt32.exe or Autorun.exe, the EULA and Product ID dialog box appear during the Setup loader phase.

Setup performs the following tasks during the GUI-mode phase:

  • Detects and installs devices found on the computer.

  • Configures each device, and installs and configures networking components.

  • Installs any optional components.

  • Copies the remaining installation files that were not copied during the text-mode phase of Setup.

  • Writes the Setup log files to the installation directory. The Setup log files are as follows:

    • Setupact.log, which contains information about all the files copied during setup.

    • Setuperr.log, which contains information about any errors that were encountered during Setup.

    • Setupapi.log, which contains information about the device driver files that were copied during Setup.

    • Setuplog.txt, which contains additional information about the device driver files that were copied during Setup.



The log files that are created during Setup can be used to help troubleshoot any installation problems that you might encounter. Double-click a log file to read it, or open it by using Notepad or a word processing application.

When GUI-mode has completed these tasks, it starts the operating system and presents the Winlogon screen. This stage of Setup is recoverable; if Setup halts, it can restart and continue where it left off.

During a clean installation of Windows 2000 Professional, Setup now prompts you to provide a user account and logon information. If you are upgrading from Windows 95 or Windows 98, Setup prompts you to supply password information.



On a new installation, you are prompted for an Administrator password; you can also personalize the installation, for example, by customizing Regional Options, Accessibility Options, and Network and Dial-up Connections settings.
