Question about Microsoft Windows XP Professional
First I have to assume that you are running Windows XP. This solution should work for other versions of Windows.
The "NTLDR is missing" error displays very shortly after the computer is first started, immediately after the Power On Self Test (POST) is complete. Windows XP has only initially begun to load when the NTLDR error message appears.
Causes of NTLDR Errors
There are a number of possible causes for NTLDR errors, including the most common "NTLDR is missing" error message.
The most common reason for this error is when your PC is trying to boot from a hard drive or flash drive that is not properly configured to be booted from; in other words, it's trying to boot from a non-bootable source. This also would apply to media on an optical drive or floppy drive that you're trying to boot from.
Other possible causes include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors, an outdated BIOS, and damaged or loose IDE cables.
How to Fix NTLDR Errors
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.
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.
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.
NTLDR Errors Apply To
This issue applies to the Windows XP operating system, including Windows XP Professional and Windows XP Home Edition.
Windows 8, Windows 7, and Windows Vista utilize BOOTMGR, not NTLDR.

Well Bart CD that everyone downloads has some nice utilities on it, some free some not.
You have to be carefull using such utilities as they can cause more harm then good...
You now have to reinstall windows before you can apply sp3. Sp3 is not bootable and bart CD doesn't have windows install of any kind on it... Reinstall windows with your disc then browse to your cd and double click on sp3 to update...
Hope everything works out now....
Please rate this solution if it helps... Thank You...

What happened is when you changed the drive letters you switched one that should not have been changed.... You need to change it back so the original C: is C:
Because the original NTLDR file was on the C: drive which is the Windows XP Boot Loader and when you swapped it it couldnt find the ntldr on the new C:
From my opinion the only way to switch it back is to reinstall the OS onto the drive you want to be C:

Pleas follow this steps to solve this problem:
1. Insert your Windows XP CD into your computer.
2. When prompted to press any key to boot from the CD, press any key. When you see the Windows XP setup menu press the "R" key to repair Windows.
3. Log into your Windows installation by pressing the "1" key and pressing enter.
4. You will then be prompted for your administrator password, enter that password.
5. Copy the files below to the root directory of the primary hard disk. In the below example we are copying these files from the CD-ROM drive letter, which in this case is "e." This letter may be different on your computer. if your cd or dvd drive is F: then replace "E:" with "F:"
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 restart your computer.

SOURCE: i have lost NTLDR and
Vista doesn't use ntldr. If it's being called for, that means the mbr was
not overwritten to point to Vista's bootloader and it's still looking for
XP's. Check the system BIOS for a protection setting that disallows writing
to the mbr (bootsector antivirus protection is a common term for it). This
needs to be disabled during setup or Vista will not be able to alter the mbr
Thanks for choosing Fixya
