# The rebuild process will step you through a number of steps depending upon how many operating systems you have on the computer and how the computer is setup. Below is a listing of the common steps you are likely going to encounter.
* Prompt for the identified versions of Windows installed. When you receive this prompt press Y if the bootcfg command properly identified each of the Windows operating systems installed on the computer. It is important to realize this command will only detect Windows XP, Windows 2000, and Windows NT installations.
* Prompt to enter the load identifier. This is the name of the operating system for the boot.ini. For example Microsoft Windows XP Home users would enter "Microsoft Windows XP Home edition".
* Prompt to Enter OS load options. When this prompt is received type /fastdetect to automatically detect the available options.
