ntldr is missing error

http://pcsupport.about.com/od/findbyerrormessage/a/ntldrmissingxp.htm

1. Restart the PC. The NTLDR error could be a fluke.
   
2. Check your floppy and optical (CD/DVD/BD) drives for media and disconnect any external drives. Often times, the "NTLDR is Missing" error will appear if your PC is trying to boot to a non-bootable floppy disk, CD/DVD/BD, or external hard drive or flash drive.
   Note: If you find that this is the cause of your problem and it's happening a lot, you might want to consider changing the boot order in BIOS so the hard drive with Windows installed is listed first.
   
3. Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including NTLDR errors.
   
   Note: There is usually an Auto setting for hard drive and optical drive configurations in BIOS which is usually a safe bet if you're not sure what to do.
   
4. Restore the NTLDR and ntdetect.com files from the Windows XP CD. Restoring these two important system files from the original Windows XP CD may do the trick:
   Enter Windows XP Recovery Console.
   When you reach the command prompt (detailed in Step 6 in the link above), type the following two commands, pressing Enter after each one:
copy d:\i386\ntldr c:\

   copy d:\i386\ntdetect.com c:\
   

   In the command listed above, d represents the drive letter assigned to the optical drive that your Windows XP CD is currently in. While this is most often d, your system could assign a different letter. Also, c:\ represents the root folder of the partition that Windows XP is currently installed on. Again, this is most often the case but your system could be different.
   If you're prompted to overwrite either of the two files, press Y.
   Take out the Windows XP CD, type exit and then press Enter to restart your PC.
   Assuming that missing or corrupt versions of the NTLDR and/or Ntdetect.com files were your only issues, Windows XP should now start normally.
   
5. Repair or replace the boot.ini file. This will prevent the NTLDR error if the cause of the problem is a boot.ini file that is not configured properly for your Windows XP installation:
   Enter Windows XP Recovery Console. The Recovery Console is an advanced diagnostic mode of Windows XP with special tools that will allow you to restore the boot.ini file.
   When you reach the command line (detailed in Step 6 in the link above), type the following command and then press Enter.
   bootcfg /rebuild
   The bootcfg utility will scan your hard drives for any Windows XP installations and then display the results. Follow the remaining steps to add your Windows XP installation to the boot.ini file.
   The first prompt asks Add installation to boot list? (Yes/No/All).
   Type Y in response to this question and press Enter.
   The next prompt asks you to Enter Load Identifier:.
   This is the name of the operating system. For example, type Windows XP Professional or Windows XP Home Edition and press Enter.
   The final prompt asks you to Enter OS Load options:.
   Type /Fastdetect here and press Enter.
   Take out the Windows XP CD, type exit and then press Enter to restart your PC.
   Assuming that a missing or corrupt boot.ini file was your only issue, Windows XP should now start normally.

6. Write a new partition boot sector to the Windows XP system partition. If the partition boot sector has become corrupt or isn't properly configured, you may receive the "NTLDR is Missing" error.
   
7. Repair the Windows XP master boot record. NTLDR error messages may also appear if the master boot record is corrupt.
   
8. Reseat all internal data and power cables. NTLDR error messages could be caused by loose or malfunctioning IDE cables.
   
   Try replacing the IDE cable cable if you suspect it might be faulty.
   
9. Update your motherboard's BIOS. Occasionally, an outdated BIOS version can cause the "NTLDR is Missing" error.
   
10. Perform a repair installation of Windows XP. This type of installation should replace any missing or corrupt files. Continue troubleshooting if this does not resolve the issue.
    
11. Perform a clean installation of Windows XP. This type of installation will completely remove Windows XP from your PC and install it again from scratch. While this will almost certainly resolve any NTLDR errors, it is a time consuming process due to the fact that all of your data must be backed up and then later restored.
    
    If you can't gain access to your files to back them up, understand that you will lose them all if you continue with a clean installation of Windows XP.
    
12. Replace the hard drive and then perform a new installation of Windows XP. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive.
