How to Solve "NTLDR Missing" error ?

The NTLDR process file loads the necessary software and system files for Windows XP and 2000 to operate properly. If you are experiencing an "NTLDR is missing" error, your NTLDR is missing, accidentally deleted or corrupted by a virus infection. To correct the problem, perform a repair installation of the operating system. Repair installations do not erase the software programs and personal files you have saved to your computer, unlike other repair methods.

Instructions

1. Insert the Windows XP or Windows 2000 Installation CD into your disk drive and restart the computer. 
2. Press the "Enter" key once the "Press any key to boot from CD" message appears on the screen. This must be done before Windows loads from the hard drive.
3. Press "Enter" in the "Welcome to Setup Screen" and press "F8" to accept the licensing terms. Highlight your operating system in the list and press "R." Windows will scan the computer for the missing "NTLDR" file and copy the necessary files to your computer. The Windows Setup Manager will open once the files are copied to your hard drive.
4. Click "Next" in the Setup Manager window and enter your personalized information for the operating system. Enter the product key in the boxes and click "Next." Set the "Administrator" password and click "Next."
5. Set the "Time and Date" settings for your region and click "Next." Select the network type and work group information, if you have any, and click "Next" to complete the repair install.
