Technician: Rogin Diez


PROBLEM

- "NTLDR Missing" text appears upon bootup
- Virus Infected


CLIENT REQUEST

- File and multimedia backup


INTERVENING FACTORS

- Motherboard support CD lost
- Peripheral drivers lost


OBSERVATIONS

- Power OK
- Unable to boot up, "NTLDR missing" code appears


TROUBLESHOOTING PROCEDURE

- Re-installation of Win XP without formatting the drives

- After successful istallation of the OS, backup requested files (Documents, Pictures, MP3's, etc..)

- Run DXDIAG by going to "Run" of the Start Menu (WIN+R) then type dxdiag,look for the motherboard description, the motherboard manufacturer for driver download reference.

- After determining the motherboard and file backup, install back the OS and I partitioned the drive twice with 50% each of the total drive space.

- After successfully installed the operating system, I then installed additional application like MS Office 03 and 07, an antivirus, USB Security, USB Safely Remove, Teracopy, Regcure, VLC, Firefox, etc..)

- Download the missing drivers from the web.

- The downloaded motherboard drivers are then installed.

- System restart was necessary then.

- After the restart, defrag the drives then assign larger virtual memory for both drives C: and D:

- Restart, then run Regcure.


REPORT

- The system was then functioning well. Computer Troubleshooting do require patience in the procedure. And careful understanding of the functions of the peripherals is a must. 0_o

NTLDR Missing NEC LL550 / G

Date Fixed : 05.04.10

Owner: Ms. Jamora

Unit: NEC LL550 / G Laptop

Operating System : Win XP SP 3

Technician: Drokz

URL : http://clhidohsr.blogspot.com

PROBLEM :

Upon Boot Up, NTLDR Missing Error appears

CLIENT REQUEST :

File Backup and if possible just to fix the NTLDR problem and retain the settings.

INTERVENING FACTORS:

Support CD is lost

Upon checking the drivers on an NEC site, the site redirects to 121ware.com and it is a Japanese site. Since I can't find the drivers for the NEC LL550 / G Laptop at 121ware.com

OBSERVATION:

Upon turning on the system, it just displays "NTLDR Missing".

Going to Safe Mode ( Pressing f8 on startup ) on startup doesn't help either. "NTLDR Missing" Error still appears.

TROUBLESHOOTING PROCEDURE :

- Fixing NTLDR Missing error can simply be corrected using some 3rd party programs. But in some cases, it might not work. I have known 2 programs that can fix this problem, one if Spotmau and the other is ERD Commander. So I first used Spotmau to try do the trick.

- I loaded in the Spotmau boot cd and waited until the Spotmau environment appeared. And on the Spotmau console, the was an option to fix the system. I opt to roll back the good state of the Operating System but it failed. So I decided to use ERD Commander.

- Upon booting up using the ERD Commander, I tried an option to fix the system. And after awhile upon finishing the fix, the system was booted up on Hard Drive ( cd was removed ) and still the NTLDR Missing Error Still persists. So I finally decided to replace the NTLDR Files using the Win XP Installer.

- To fix the NTLDR files, the files should be replaced. In order to replace or fix the NTLDR files, we need to load in our Win XP SP2 and boot it up ( restart the system )

- You should see after awhile some options to what you should be doing in the set up. Now, I chose "Repair". A minute after, you should be prompted to choose the OS and to supply the administrator password for that installed Operating System. Then, the command line now appears. In the command line, type in "copy e:\i386\ntldr c:" then afterwards copy another file and type in "copy e:\i386\ntdetect.com c:" ( please do not include the quotation and e: should be replaced by the drive letter of your cd rom drive or dvd rom drive ). Please remember that wherever you installed your Operating system ( aside from the default partition which is c: ), copy the ntdetect.com and ntldr files to drive c:. :-) I tried copying the files to drive d: where I installed the Operating System and it DIDN't WORKED.

- After copying ntdetect.com and ntldr from the I386 folder of the XP Installer and booted up the system, everything went running well and the NTLDR Missing problem now resolved.

SUMMARY:

- Using Spotmau or ERD Commander does not always guarantee to fix NTLDR Missing problems. Sometimes, we need to manually do it by copying the ntdetect.com and NTLDR files from the I386 folder of the Win Xp Installer. This can only be achieved in the "Repair" mode of the Win XP Setup environment using command the command line.

- Somehow using Spotmau or ERD Commander makes your job quicker and there are a lot more options to do only Spotmau and ERD Commander can do like System Rollback, File Backup, Driver Backup, and many many other useful tools to play with. :-) You can also try and purchase this guidebook through Amazon to do disk defragmentation, file and system recovery, administrative tasks, and using third party programs effectively.

Troubleshooting NTLDR Missing in XP

Boot Loader or NT Loader or NTLDR is a program necessary for XP, Win 2003 Server, Win 200, and Win NT 4.0 to boot up or make boot selections. These NT based operating systems requires two files for booting up, namely NTLDR and NTDETECT.COM. If or either NTLDR and NTDETECT.COM is or are missing or corrupted, the operating system reports after POST a text string indicating that your Operating System can't be loaded.

Corrupted or missing NTLDR or and NTDETECT.COM is caused by either hardware or software problem. IF hardware related, the power supply or the hard drive should the most probable cause of the problem. And in some instances, a virus attack could have done the fault.

In order to fix "NTLDR Missing", we will make the process easy by using a utility called Hiren. Hiren is a bootable CD that contains many useful utilities including Mini XP. We will be using Mini Cp in this tutorial thru using Hiren's CD. You must also have your original Win XP installer.

Steps to fix "NTLDR Missing" in Xp

1. Change the boot sequence in your BIOS by pressing DEL or F2 after turning on the computer. Go to the Boot options and make your DVD ROM or CD ROM the first boot priority. Load the Hiren CD into your optical drive and press F10 to save and exit.

2. As the computer boots up it will show you a splash screen with options, choose boot from Mini Xp. Upon booting from Mini Xp, you will actually be using your RAM as the main drive. Wait until Mini XP fully boots up and be functional.

3. In the Mini XP environment you will see that it is not so different with the normal XP. Now go to "My Computer" and locate the drive which you have installed XP which is usually at drive C: by default. Try to browse the files and find both NTLDR and NTDETECT.COM, we will be replacing these files in the next step below.

4. Eject Hiren's CD from the drive and replace it with you Win XP CD. Go to "My Computer" and explore the contents of your Win Xp cd. Got to the I386 folder then find and copy NTLDR and NTDETECT.COM and paste it in your Drive C:. You should replace the existing NTLDR and NTDETECT.COM files of your Local Drive C: from the two files we copied from your Win Xp installer.

5. Eject the Win Xp installer. Restart your computer. You should be able to fix "NTLDR Missing" after.

6. If it doesn't work, please comment so we can trace which part you did miss.
