There may be times when you forget to perform a pre-installation task prior to starting the Windows Server 2008 installation. Rather than restarting the operating system, you can access a command prompt from Setup or use advanced drive options to perform the necessary administrative tasks.
When you access a command prompt from Setup, you access the MINWINPC (mini Windows PC) environment used by Setup to install the OS. During installation, on the 'Where Do You Want To Install Windows' page, you can access a command prompt by pressing 'Shift+F10'. The mini Windows PC environment provides access to many of the same command-line tools that are available in a standard installation of Windows Server 2008. Here is a list of what is available:
