Question about Sony VAIO F340 Notebook

1 Answer

Boot up failure

I have Sony VAIO This system will not boot and brings up the error NTLDR missing. I know that is a file needed to get XP to run. I am pretty sure that the recovery console (chkdsk /r) will bring it back
but don't have an XP pro CD to use. System came with its own custom factory restore disk, which as far as i know doesn't have the recovery console I have had this issue on another system before. Is the recovery console in XP home the same as XP pro? Would it bring it back? I have also heard that putting that drive in another XP system, will cause XP to fix its own errors on the other drive. Is that true?

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.

Nltdr missing


How To: Fix "NTLDR is missing"

Applies to: Microsoft Windows NT, Windows 2000, Windows XP

Symptoms

When you start your computer, you receive the error message "NTLDR is missing. Press any key to restart."

Cause

The error message "NTLDR is missing" means that the Windows boot loader (NT Loader, NTLDR) cannot be found. This oftenoccurs when the computer tries to boot from a drive other than the one Windows is installed on, due to a change in the driveconfiguration or because you left a bootable disk in a removable drive. But it may also be because the NTLDR file has beencorrupted or deleted.

SolutionCheck the boot drives

First, check the boot drives to make sure that the computer is not trying to boot from a different drive to the one thatcontains Windows.

  • Check that there are no CDs or DVDs in the CD/DVD drives.
  • Check that no removable drives are plugged in to the USB ports.
  • Check the boot order in the BIOS Setup to ensure that the computer boots from the drive containing Windows before any other bootable devices.

If this does not resolve the problem, you will have to repair the NT boot loader.

Fix NTLDR

The easiest way to fix the "NTLDR is missing" error is to use Spotmau PowerSuite.However, if your computer is using Windows XP and you have a Windows XP installation CD you may be able to boot from this anduse the Recovery Console to fix NTLDR manually instead.

Use Spotmau PowerSuiteInsert the Spotmau PowerSuite CD and start the computer. The main menu will appear.spotmau-2.gif
  • Click 2. Windows Recovery.
spotmau-2-1.gif
  • When the Windows Recovery tool starts, click Windows NT/2000/XP/2003.
spotmau-2-1-1a.gif
  • On the Windows NT/2000/XP/2003 Recovery dialog, click Recover NTLDR and NTDETECT.
spotmau-2-1-1a-1.gif
  • On the Recover NTLDR and NTDETECT dialog, select your operating system (e.g. Windows XP) and then click Recover.
spotmau-2-1-1a-2.gif

The tool will repair the file and report "NTLDR and NTDETECT have been recovered successfully."

  • Remove the Spotmau PowerTools CD from the drive and click Restart to reboot the computer.

What is NTLDR error sir?


NTLDR (abbreviation of NT Loader) is the boot loader for all releases of Microsoft's Windows NT operating system up to and including Windows XP and Windows Server 2003. NTLDR is typically run from the primary hard disk drive, but it can also run from portable storage devices such as a CD-ROM, USB flash drive, or floppy disk. NTLDR can also load a non NT-based operating system given the appropriate boot sector in a file.
NTLDR requires, at the minimum, the following two files to be on the system volume:
  • NTLDR, which contains the main Boot loader itself
  • boot.ini, which contains configuration options for a boot menu.

This error means that NTLDR is missing somehow from your computer,hard disk problem,virus.etc
You can go to that page and follow the instructions exacty as he says and your problem will gone:)

NTLDR missing


I can get into the Boot First Screen but can't seem to change anything within it... These screens seems to be selectively responsive to my key presses.... I can get the bios screen up, boot order screen up but not necessarily do anything within them... e.g. I can't restart the pc using ctrl alt del when the missing NTLDR message appears.... also I have put an XP disc in and it says to press any key to BOOT from CD .... I Do so but obviously it doesn't recognise it so it gives me the missing NTLDR message again! :(
