To install the Recovery Console, insert the Microsoft Windows 2000 Professional CD-ROM into your CD-ROM drive, and close the Microsoft Windows 2000 CD dialog box, if it opens. Open the Run dialog box or a Command Prompt window in Windows 2000, change to the i386 folder on the Windows 2000 CD-ROM, and then run the winnt32 command with the /cmdcons switch. After you install the Recovery Console, you can access it from the Please Select Operating System To Start menu. You can also use the Windows 2000 Setup disks or the Windows 2000 Professional CD-ROM to start your computer and then select the Recovery Console option, when you are prompted to choose repair options, to access the Recovery Console.
After you start the Recovery Console, you must specify which installation of Windows 2000 you want to log on to (if you have a dual boot or multiple boot configuration), and then you must log on as Administrator.
You can also run the Recovery Console from the Windows 2000 installation CD-ROM. The Recovery Console provides you with a limited set of administrative commands that you can use to repair your Windows 2000 installation.
