how to repair NTLDR is Missing



When you start your Windows XP-Based computer, you may receive the following error message:

NTLDR is missing
Press CTRL+ALT+DEL to restart

This problem may occur if one or more of the following windows boot files are missing or corrupted:

Ntldr
NTDETECT.COM
Boot.ini
To resolve this issue, you need an original or untouched copy of windows XP, and  configure the computer to boot from the CD-ROM or DVD-ROM drive and follow this steps.

1. Insert the Windows XP bootable CD into the computer.
2. When prompted to press any key to boot from the CD, press any key.

3. Once in the Windows XP setup menu press the "R" key to repair Windows.

4. Log into your Windows installation by pressing the "1" key and pressing enter.
5. You will then be prompted for your administrator password, enter your password is you have any, otherwise just press Enter.
6. Copy the below two files to the root directory of the primary hard disk."e:" is your CDROM drive letter & "c:" is your Windows OS partition. This letter may be different on your computer.
      copy e:\i386\ntldr c:\
      copy e:\i386\ntdetect.com c:\
 7. Once both of these files have been successfully copied, remove the CD from the computer and reboot.

Normally NTLDR & NTDETECT.com are hidden files. So after you've copied to Windows OS partition type this commands

c:\attrib ntldr +r +s +h and press enter
c:\attrib NTDETECT.COM +r +s +h and press enter

and your system should now boot normally.
