NTLDR is missing?

A missing NTLDR is a common start up error that can appear on the screen while booting a computer running a Windows operating system. This error may occur due to number of reasons.

NTLDR is short for Windows 'NT LoaDeR'. It's entirely involved in the loading of the operating system.

Many times this error is caused when the computer is attempting to boot from a non-bootable floppy disk/hard drive that contains no operating system or CD-ROM drive. Firstly what you've got to to is press the Delete key multiple times as your computer boots up until it displays the BIOS screen. Then you will need to find the boot disk priority setting. Make sure this is set to your drive that has Windows on it (as priority 1) and not the CD-ROM drive/stiffy drive or empty hard drive. You can set the CD-ROM/DVD-Rom drive to priority 2 if you like.

Once you have checked that and have set it to your master/primary hard drive (the one that you've installed Windows onto), save and exit the BIOS and on reboot your system should boot into Windows normally.

If you only have one hard drive and the boot disk priority 1 is set to it and you still get this message, then it means that your NTLDR is either corrupted or missing. In the BIOS you will need to change boot disk priority 1 to your CD/DVD drive. Once this is done save and exit the BIOS.
As the PC reboots insert your Windows install disk and let it load.

Hit [R] when prompted if you need to repair system files and then [C] at the 'Welcome to Setup' screen to start the Recovery Console. This will let you copy NTLDR from the CD to C:\

If this fails then you will need to install a fresh copy of Windows on your system. All is not lost though as you can still save your data that is trapped on the NTLDR missing hard drive. If you are not quite seasoned with computers and electronics then this is the job for a PC technition. Simply take your PC down to your local Computer store and explain your situation (Don't forget to take your original Microsoft Windows with you). They will back up your data, re-install Windows and the put all your data back on for you.

Ntldr is missing press ctlr+alt+ and delete to restar and i did and don't workz


First I have to assume that you are running Windows XP. This solution should work for other versions of Windows.
The "NTLDR is missing" error displays very shortly after the computer is first started, immediately after the Power On Self Test (POST) is complete. Windows XP has only initially begun to load when the NTLDR error message appears.
Causes of NTLDR Errors
There are a number of possible causes for NTLDR errors, including the most common "NTLDR is missing" error message.
The most common reason for this error is when your PC is trying to boot from a hard drive or flash drive that is not properly configured to be booted from; in other words, it's trying to boot from a non-bootable source. This also would apply to media on an optical drive or floppy drive that you're trying to boot from.
Other possible causes include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors, an outdated BIOS, and damaged or loose IDE cables.
How to Fix NTLDR Errors
1.Restart the PC. The NTLDR error could be a fluke.

2.Check your floppy and optical (CD/DVD/BD) drives for media and disconnect any external drives. Often times, the "NTLDR is Missing" error will appear if your PC is trying to boot to a non-bootable floppy disk, CD/DVD/BD, or external hard drive or flash drive.
Note: If you find that this is the cause of your problem and it's happening a lot, you might want to consider changing the boot order in BIOS so the hard drive with Windows installed is listed first.

3.Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including NTLDR errors.
Note: There is usually an Auto setting for hard drive and optical drive configurations in BIOS which is usually a safe bet if you're not sure what to do.

4. Restore the NTLDR and ntdetect.com files from the Windows XP CD. Restoring these two important system files from the original Windows XP CD may do the trick.

5. Repair or replace the boot.ini file. This will prevent the NTLDR error if the cause of the problem is a boot.ini file that is not configured properly for your Windows XP installation.

6. Write a new partition boot sector to the Windows XP system partition. If the partition boot sector has become corrupt or isn't properly configured, you may receive the "NTLDR is Missing" error.

7. Repair the Windows XP master boot record. NTLDR error messages may also appear if the master boot record is corrupt.

8. Reseat all internal data and power cables. NTLDR error messages could be caused by loose or malfunctioning IDE cables.
Try replacing the IDE cable cable if you suspect it might be faulty.

9. Update your motherboard's BIOS. Occasionally, an outdated BIOS version can cause the "NTLDR is Missing" error.

10. Perform a repair installation of Windows XP. This type of installation should replace any missing or corrupt files. Continue troubleshooting if this does not resolve the issue.

11. Perform a clean installation of Windows XP. This type of installation will completely remove Windows XP from your PC and install it again from scratch. While this will almost certainly resolve any NTLDR errors, it is a time consuming process due to the fact that all of your data must be backed up and then later restored.
If you can't gain access to your files to back them up, understand that you will lose them all if you continue with a clean installation of Windows XP.

12. Replace the hard drive and then perform a new installation of Windows XP. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive.
NTLDR Errors Apply To
This issue applies to the Windows XP operating system, including Windows XP Professional and Windows XP Home Edition.
Windows 8, Windows 7, and Windows Vista utilize BOOTMGR, not NTLDR.

After system recovery using recovery discs of "PowerSpec" error message "NTLDR is compressed PressCtrl Alt Del to restart" appears .How to fix it


When NTLDR is missing from your operating system it means that there is a problem with your boot loader, a bootstrap process that begins when you turn on the computer. A missing NTLDR means that your computer cannot boot to the operating system. This issue is only a problem on computers running Windows XP or previous operating systems as Windows 7 and Vista don't utilize NTLDR. Loose or Faulty IDE/EIDE hard disk drive cable. Failing to enable USB keyboard support in the BIOS. Many times this error is caused when the computer is attempting to boot from a non-bootable floppy disk or CD ROM First verify that no Floppy Diskette or CD is in the computer, unless you are attempting to boot from a diskette. Fixing the missing NTLDR is relatively easy so long as you have your installation disc.
Locate your Windows XP/2000 installation disc and place it in your CD/DVD ROM drive. If you don't have this disk, then you cannot proceed further. Restart your computer. When the computer restarts press any key on your keyboard when you are prompted, "Press any key to enter setup." Most computers are configured to boot to another device other than a hard drive. Since the Windows XP/2000 installation disk is bootable, you should see the prompt. However, if you don't see the prompt you may need to change your boot priority in your BIOS. To do so, enter the system BIOS by following the onscreen instructions upon startup. Then navigate to the Boot Priority menu and modify another device, such as a CD-ROM to boot prior to the hard drive. Then reboot your computer. After you have pressed any key, the Windows XP/2000 setup screen will appear. After loading, press the "R" key to repair the Windows installation. The screen will appear black. The computer requests which installation you would like to log in. Generally speaking, press "1" and "Enter." If you have more than one hard drive or more than one partition, the procedure may be different. You must know which hard drive or partition your Windows operating system is installed in. You are subsequently prompted for a password. If you haven't set up one up, you can just leave the query blank and press "Enter." The phrase "c:\WINDOWS>" and a blinking cursor subsequently appear. Type "copy d:\i386\ntldr c:\windows" (without quotes), where "D" is the letter of your CD/DVD ROM drive (your optical drive may be different, especially if you have more than one). Eject the CD from the drive and type "Exit" (without quotes) to restart your computer. The NTLDR file will be copied from the installation disc to your hard drive.

or If you've started your Windows XP computer and you see an error message to the effect that the "NTLDR" file is missing or corrupted, you've probably also noticed that the computer refuses to boot any further. This is because the NTLDR file is an integral part of the boot process and needs to be restored before the boot process can proceed normally.

Insert your Windows XP disc into your computer. Restart the computer and press any key on your keyboard when the message prompting you to do so appears. Press the "R" key to open the Recovery Console and then press "1" and "Enter" in order to select your operating system. Type in your Administrator password (if needed) and press "Enter." Type "copy d:\i386\ntldr c:\" and press "Enter" and then type "copy d:\i386\ntdetect.com c:\" and press "Enter." Restart your computer and let it boot up normally. Since the NTLDR is freshly restored, the computer boots up properly. Hope this helps.
