Solution to NTLDR is missing

Fault Phenomenon: boot self-check is normal, but it gets stuck when you enter the system, that is, when the system is guided.

NTLDR is missing, Press CTRL + ALT + DEL to restart.

After thinking, we can find that:

1. XP is the NT kernel, and LDR is the abbreviation of loader commonly used in the operating system. Therefore, the fault may be caused by the loss of the system boot file, and the file name is NTLDR.

2. The computer is stuck when it enters the operating system, that is, the system boot, so it is determined that it can be unable to perform system boot and thus cannot enter the operating system.

The fault description on the official Microsoft website is as follows:

The error message "NTLDR is missing" (NTLDR missing) is returned when the computer is started.
Symptom
After copying multiple files to the root folder of the boot volume using the NTFS file system, the following error message may be received the next time you start the computer:

NTLDR is missing
Press CTRL + ALT + DEL to restart.
If you delete a file that is copied to the root folder, the index allocated to the master file table (MFT) will not be reduced to the original size.
Cause
This problem may occur if the MFT root folder contains many fragments. If the MFT root folder contains multiple files, MFT becomes very fragmented and requires another allocation index. Because files are mapped to the allocation index alphabetically, NTLDR files may be pushed to the second allocation index. If this happens, you will see the error message described in the "symptoms" section in this article.

Generally, files are not written to the root folder. This situation occurs if a program regularly creates and deletes temporary files in the root folder, or copies many files to the root folder by mistake.

Alternative Method
To solve this problem, create a boot disk to start your computer.

According to our own conclusions and descriptions on the official Microsoft website, we can use the "Compensation Method" to repair the file, that is, copy the original file from another system disk or computer, you can enter the operating system normally.

The following are my experiences and solutions summarized on the Internet:

(Step 1) Enter

Copy G: \ i386 \ ntldr c: \ (Press ENTER ),

Then enter:

Copy G: \ i386 \ ntdetect.com c: \ (Press ENTER)

At this time, the system will prompt something, enter y... and press enter... (The problem should be resolved here. The next step is to confirm that the problem has not been resolved .)
Enter c: \ Boot. ini. If the information in Boot. ini is displayed normally, restart the system. The problem is solved ..

Summary:

The NTLDR file is a WinXP boot file. Back up data when the system is normal.
Description of NTLDR files: NTLDR is a hidden, read-only system file used to load the operating system.

Extraction of NTLDR files: The NTLDR file is a WinXP boot file. When this file is lost, the startup system prompts that it is missing and requires any key to restart. The NTLDR file cannot enter the WinXP system correctly. You can extract the file from the fault recovery console. The file is stored in the i386 directory of the installation disc. The extraction method is as follows:
Go to the system fault recovery console, go to drive C, enter "copy X \ I386 \ NTLDR" (Note: Here X is the drive letter), and press Enter, if the system prompts whether to overwrite, press "Y", and then enter the exit command to exit the console and restart.

Appendix:

The guiding process of the XP system:
1. The power self-check program starts running.
2. The Master Boot Record is loaded into the memory and the program starts to execute.
3. The Boot Sector of the active partition is loaded into the memory.
4. NTLDR is loaded from the boot sector and initialized
5. Change the real mode of the processor to 32-bit smooth memory mode.
6. NTLDR starts to run the appropriate small file system driver. The small file system driver is built inside NTLDR and can read FAT or NTFS.
7. Read the boot. ini file through NTLDR.
8. NTLDR mount the selected Operating System

* If NT/XP is selected, NTLDR runs Ntdetect.com
* For other operating systems, NTLDR loads and runs Bootsect. dos and then transmits control to it.
The windows NT process ends.

9.Ntdetect.com search for computer hardware and send the list to NTLDR to write the information into HKE Y_LOCAL_MACHINEHARDWARE.
10.then ntldrloads ntoskrnl.exe, Hal. dll, and system information.
11. Ntldr searches for a collection of system information and loads the device driver configuration so that the device starts to work at startup.
12.ntldrgrant the control permission to ntoskrnl.exe. At this time, the startup program ends and the loading phase begins.

The following is my personal experience and hope to help you a little bit.
