First is Locate an NTLDR file in a working windows server 2003
The NTLDR file is a critical boot file for the Windows 2000, XP and Server 2003 operating systems. The NTLDR file is found in the root of your boot drive, but it is hidden by default. Windows hides critical boot files so you do not accidentally delete the file thinking it is an unimportant part of the computer. The file is always located in the root of your drive, but before you can find it, you must set the operating system to show hidden files.
