Today's own machine out of this problem, look at the XP solution below
NTLDR is generally stored in the C-packing directory, is a hidden and read-only properties of the system files. Its primary responsibility is to parse Boot.ini files.
The loss of a NTLDR file can easily occur when a power outage or installation of a lower version of the operating system is installed on a high version, so that when you log on to the system, a failure prompt for the "NTLDR is Missing press no key to restart" appears, which can be found in the Recovery Console To resolve.
Enter the Recovery Console, then enter the "copy x:i386ntldr C:" Command in the Recovery Console command and return ("X" is the letter of the CD drive), and then execute the copy x:i386ntdetect.com C: command. If you are prompted to overwrite the file, type "Y" to confirm and press ENTER.
In the event of a NTLDR file loss, the Boot.ini file is likely to be lost or corrupted. This will also perform the "Bootcfg/redirect" command in the Recovery Console to rebuild the Boot.ini file after the NTLDR operation is repaired. Finally, execute the "fixboot C:" Command and enter "Y" to confirm and return when you are prompted to do so, so that the Windows XP system partition can be written to the boot sector. When the full command is executed, type the "Exit" command to exit the Recovery Console and the system will resume as soon as it restarts.
