NTLDR will default to \Windows on the first partition of the first hard drive.
Ntldr located is C:\i386\ntldr C:\i386\ntdetect.com or C:\WINDOWS\ServicePackFiles\i386\ntldr posted by Josepharulselvan.R
One of you windows operating system important files has been corrrupted,deleted or unreadable.That will be the main cause that your NTLDR cant load. I found it similar to this one. It is worth pointing out that the ntldr file is usually missing due to virus attack. You hould run an antivirus scan as soon as possible after you have repaired on the disk.
NTLDR is indeed a key boot file in Windows 2000 and all of the Windows operating systems since Windows NT. A machine will not boot without that file.
The initial self-test will fail to load.
Boot from Windows XP CDSelect into boot menu "Restore Console" or smth like that copy X:\i386\ntdlr C:\copy X:\i386\ntdetect.com C:\Type this commands (X - is a letter of your CD/DVD drive; C - is disk where Windows XP installed):Reboot.Done.
