Solution for NTLDR is missing-hardware maintenance

Failure phenomenon: Post all normal, but in the system, that is, the system to boot when stuck, show

NTLDR is missing,press Ctrl+alt+del to restart.

After thinking, the analysis concludes:

The 1.XP system is NT kernel, and LDR is the abbreviation of common loader in the operating system, so this fault may be caused by the loss of system boot file, and the name of the file is NTLDR

2. The computer is stuck when it enters the operating system, that is, when the system is booted, so it is judged that it may not be able to lead the system to enter the operating system.

The following is a description of the failure of Microsoft's official website:

You receive the "NTLDR is Missing" (missing NTLDR) error message when you start your computer
Symptoms
After you copy multiple files to the root folder of the boot volume that uses the NTFS file system, you may receive the following error message the next time you start your computer:

NTLDR is missing
Press Ctrl+alt+del to restart.
If you delete a file that is copied to the root folder, the Master File table (MFT) allocation index does not drop to its original size.
Reason
This problem may occur if the MFT root folder is more fragmented. If the MFT root folder contains more than one file, the MFT becomes so fragmented that a separate allocation index needs to be created. Because the files are mapped alphabetically to the allocation index, the NTLDR file may be pushed to the second allocation index. If this behavior occurs, you will see the error message that is described in the "Symptoms" section of this article.

In general, files are not written to the root folder. This can occur if a program periodically creates and deletes temporary files in the root folder, or mistakenly copies many files to the root folder.

From the conclusions of their own and Microsoft's official website, we can use the "compensation method" to repair, that is, the original loss of the file from other system disk or computer copy over to it, you can normally enter the operating system.

here are some solutions for your experience and online summary:

(Step one) through the Recovery Console (assuming the G disk is the CD drive letter ...) Input

Copy G:\i386\ntldr C:\ (carriage return),

And then enter:

Copy G:\i386\ntdetect.com C:\ (carriage return)

At this point, the system to indicate what, enter Y. Then press ENTER again. (The problem should be solved, the next step is to determine, the problem is not solved.)
Then enter C:\Boot.ini, if you can display the information in the Boot.ini, then restart, then the problem is solved.

Summary of questions:

The Ntldr file is a WinXP boot file. Backup should be given when the system is normal.
Description of the NTLDR file: NTLDR is a hidden, read-only system file that is used to load the operating system.

NTLDR file Extraction: NTLDR file is a WinXP boot file, when this file is lost when the boot system will be prompted to be missing and required to press any key reboot, can not correctly enter the WinXP system. The file can be extracted under the Recovery Console, which exists in the I386 directory of the installation CD, and is extracted as follows:
Enter the system Recovery Console, go to C disk, enter "Copy X\i386\ntldr" (Note: Here the X is the optical drive letter) and enter, if the system prompts to overwrite then press "Y", then enter the Exit command to exit the console reboot.

attached:

The boot process for the XP system:
1, the power of self-test program began to run
2. The master boot record is loaded into memory and the program starts executing
3. The boot sector of the active partition is loaded into memory
4. NTLDR is loaded and initialized from the boot sector
5. Change the processor's real mode to 32-bit smooth memory mode
6, NTLDR start to run the appropriate small file system driver. The small file system driver is built inside the NTLDR, and it can read FAT or NTFS.
7, NTLDR read Boot.ini documents
8, NTLDR load the selected operating system

* If Nt/xp is selected, the NTLDR runs Ntdetect.com
* For other operating systems, NTLDR loads and runs Bootsect.dos and then passes control to it.
The Windows NT process is complete.

9.ntdetect.com searches the computer hardware and passes the list to NTLDR to write the information into Hke Y_local_machinehardware.
10. Then NTLDR loads the Ntoskrnl.exe,hal.dll and System i

12.Ntldr the control to Ntoskrnl.exe, at this time, the start of the program is completed, loading phase began


Here is a personal experience, I hope to give you a little help.
