INTRODUCTION
This article discusses the bootcfg command and its uses.



MORE INFORMATION
The bootcfg command is a Microsoft Windows XP Recovery Console command that manipulates the Boot.ini file. This command has a function that can scan your hard disks for Microsoft Windows NT 4.0, Microsoft Windows 2000, and Windows XP installations, and then add them to an existing Boot.ini file. The function can also rebuild a new Boot.ini file if one does not exist. With the bootcfg command, additional Boot.ini file parameters can be added to existing or new entries.

To use the bootcfg command, start the Recovery Console with the Windows XP CD-ROM, and then click Recovery Console. Or, install the Recovery Console locally, and then select the command from the Boot menu.

The bootcfg command has the following uses:  The bootcfg /default command sets the default operating system option in the Boot menu. The command selects the operating system entry automatically. The bootcfg /add command scans the computer for Windows NT 4.0, Windows 2000, or Windows XP (if it is dual booting) installations, and then displays the results. From this location, you can add an installation to the Boot menu.

You may receive a message that is similar to the following message:

[2] D:\Windows

Select installation to add: (select a number)

Enter Load Identifier: (Custom description for an operating system loading from the Boot menu)

Enter Operating System Load Options: (that is: /fastdetect)

This process adds a new entry in the Boot menu. When you add an installation, the bootcfg command also makes the installation the default operating system boot entry. The bootcfg /rebuild command scans the hard disks of the computer for Windows NT 4.0, Windows 2000, or Windows XP installations, and then displays the results. You can add the detected Windows installations.

You may receive a message that is similar to the following message:
