How to Fix Missing NTLDR and Ntdetect.com files

Ntdetect.com and NTLDR files provide the Windows operating system with the ability to bootinto its user interface. Both files are required by Windows to boot, so the error that the files are

missing leaves you unable to use the machine. You can replace these files and fix your Windowsmachine using the Recovery Console and the Windows installation CD. The files are copied

back to the hard drive and the machine is able to boot Windows again.

Press the Enter key. Replace x with the drive letter of yourCD orDVD drive andreplace C with the drive location for the Windows installation.


25/37

5. Step 5Remove the boot disk and reboot your machine. Windows boots and the error is corrected

What to Do if Youre Missing an NTLDR File

NTLDR is an essential file for the Windows operating system. With the inception of Windows 2000,

Microsoft changed the way the operating system boots. There are two common files that become

corrupted or are accidentally deleted by users: NTLDR and ntdetect.com. When these files are removed,

the computer no longer boots and an error appears the next time the system is started.

The Boot Device

y First, check the floppy and CDROM drive. If a non-boot floppy disk or CD is in these drives, the

computer attempts to find the NTLDR file on the disk or CD. If the file is not found, the error is displayed.

Ensure that no CD or floppy disk is in either of these drives.

This error can also happen because of a simple misconfiguration in the BIOS. The BIOS is the first code

that registers when the computer is started. The BIOS points to the section of the hard drive where boot

files are located. If the files are missing or corrupt, the system is unable to boot and the missing NTLDR

error occurs.

In the BIOS, there is a setting that sets the order in which a computer searches for the operating-system

files. For most systems, the order is the floppy-disk drive, the CD-ROM drive and then the hard drive.

This is how the computer knows to boot from a CD-ROM rather than the hard drive when a boot disk is

present.

Ensure that the BIOS is configured to boot from the CD-ROM or floppy drive first. The last boot device

should be the hard drive.

Restore the File

y If the BIOS is correctly configured, the best way to fix the error is to restore the files from the

Windows CD.Since the Windows CD is a boot disk, insert it into the drive and restart the computer. The

computer detects the CD and starts the process of repair and installation. The first screen asks if you

want to repair the system. Click the R button and continue through the licensing agreement and

prompts.

The system will ask for a username and password for the administrator account. Once this password is

entered, the user is sent to a DOS prompt. This requires a little knowledge of DOS commands since the

NTLDR and ntdetect.com files need to be manually copied onto the hard drive. When prompted for a

command, the following two statements copy the necessary files to the hard drive:

copy e:\i386\ntldr c:\

copy e:\i386\ntdetect.com c:\

The e drive in this example is the computers CD-ROM drive. If the CD-ROM drive has another alias,

use it in place of the e in this example. For most people, the c drive is the main boot drive. If the

system has a different hard drive letter, that should replace the c notation in the example.

Once the files are copied, the CD can be removed and the computer rebooted. If the problem stems

from a missing or corrupt file, the computer will start normally. However, if the error persists, the hard


26/37

drive may be faulty.A faulty drive cannot be recovered, especially if the boot sector is damaged. The

only option for users with a damaged hard drive is to purchase another and install it in the machine.

How to Reinstall XP Bootloader

Reinstalling Windows XP often means formatting your computer. However, due to viruses and

hardware failure, all you may need to reinstall is the Windows XP bootloader. You can reinstall the

Windows XP bootloader without formatting or losing your files.Some of the main causes of a missing

Windows XP bootloader are viruses, hardware failure, or an error during the Windows XP installation. If

a missing bootloader is your only problem, restoring the bootloader takes only a fraction of the time you

would spend reinstalling Windows

5. Step 5Type fixboot C: at the command prompt. If Windows XP isnt installed on C:, enter the

correct drive letter instead.

How to Fix XP Blue Screen of Death

In Dantes tenth circle of Hell, unrepentant Microsoft designers eternally and unsuccessfully

troubleshoot the STOP error, more commonly known as the Blue Screen of Death (BSOD). Here on

Earth, the BSOD is only slightly less troublesome. The BSOD gets its vivid nickname from the blue

background screen. On the screen, you will see a message in white letters, describing the problem. The

message can be cryptic, however, and sometimes appears too briefly to be useful. In Windows XP, the

BS

OD can lock you into a cycle of reboots and errors, unless you know the steps to extricate yourself

the BSOD can lock you into a cycle of reboots and errors, unless you know the steps to extricate

yourself.

Instructions

1. Step 1If a STOP error appears during Windows Setup, it is usually due to a faulty device driver.

Bypass the error by pressing F6 when prompted at the beginning of Setup, then check forcompatible drivers on the Internet.

2. Step 2If a STOP error appears during start-up, and Windows XP was previously running

properly, it is likely due to an incompatible software application or device driver thatyou recently installed. Remove the device or uninstall the program, and restart your

computer.

3. Step 3If Windows hangs during start-up, use your Windows CD to start the computer. If youneed to do repairs, and you are comfortable working at the command line, enter the

Recovery Console by pressing R at the Welcome to Setup screen. Type help for alist of commands.

4. Step 4If a STOP error appears while Windows is running, it could be caused by drivers,

services or hardware problems. The text on the screen may help you pinpoint theproblem.

5. Step 5If your computer restarts before you can read the STOP error text, view the details in the

Event Log. Open Control Panel>Administrative Tools>Event Viewer. In the left-handpane, click on System Log. Filter entries to show only error events by choosing

View>Filter; click the Filter tab, and clear all checkboxes except Error. Scrollthrough the entries to find the time and date your computer crashed, and double-click the

29/37

Read the BSOD text, which might say something like, If this is the first time youveseen this Stop error screen, then an explanation and directions. Follow the instructions

and see whether they correct the problem. If another BSOD appears, decode the rest ofthe STOP error in order to search for a solution.

7. Step 7Find the symbolic error name. At the top of the BSOD, under the message beginning, A

problem has been detected, the symbolic error name appears in capital letters. One

common symbolic error name is DRIVER_IRQL_NOT_LESS_OR_EQUAL.

8. Step 8Decode common abbreviations.

IRQL (pronounced Urkel) stands for interrupt request level.

KMODE stands for kernel mode.

PTES refers to page table entries (PTEs).

HAL stands for hardware abstraction layer.

9. Step 9Locate the error number. Under Technical Information, after the word STOP, youwill find an error number (in hexadecimal), such as 0x0000003F. The numbers

following the error number, in parentheses, are parameters.

10.Step 10Start your computer in Safe Mode, then search Microsofts Knowledge Base, using thesymbolic error name or error number as your search term.
