When you use the Recovery Console, you are working at a special command prompt instead of the ordinary Windows command prompt. The Recovery Console has its own command interpreter.
To enter this command interpreter, you are prompted by Recovery Console to type the local Administrator password.

When the Recovery Console starts, you can press F6 to install a third-party SCSI or RAID driver, in case you need such a driver to access the hard disk. This prompt works the same as it does during installation of the operating system.

The Recovery Console takes several seconds to start. When the Recovery Console menu appears, a numbered list of the Windows installations on the computer appears. (Generally, only c:\Windows exists.)
Press a number before you press ENTER, even when only one entry appears. If you press ENTER without selecting a number, the computer restarts and begins the process again.
When you see the prompt for %SystemRoot% (generally C:\Windows), you can start using the available commands for the Recovery Console.
