Updated: 04/26/2017 by Computer Hope
Users who have a corrupt or missing boot.ini file, are running Microsoft Windows XP, and have a Microsoft Windows XP CD can rebuild the systems boot.ini file by following the steps below.
- Insert the Microsoft Windows XP CD into the computer. Note: If you have a system recovery CD or restore CD (not a Microsoft CD) these steps may not work for your computer.
- Reboot the computer with the CD and press any key when prompted to press any key to boot from the CD.
- Once in the Microsoft Setup menu press R to open the recovery console.
- Select the operating system you want to use; if you only have Windows XP on the computer you will get one prompt.
- Once prompted for the password enter the Admin password and press enter.
- Once at the command prompt type bootcfg /rebuild to start the rebuild process.
- 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 only detects Windows XP, Windows 2000, and Windows NT installations.
* Prompt to enter the load identifier. The load identifier 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.
- Once you have completed all the available options in the rebuild and are back at the prompt type exit to reboot the computer.
