What’s your favorite website : FaceBook or youtube to share with others via comment below) ..I have been in touch with many of those local computers experts who feel proud in calling them “Engineer”. Majority of them thinks this disease cannot be cured and the only way left now is to Boot up from a Windows CD and let the computer Born again, I mean Format and re-install after which it becomes a new baby. You will have to teach him about your needs once again. If you are rude enough you will surely bother the hard drive spindle of servers lying in Google’s data centers to get some information for you on this problem. Google servers are helpful enough. if you share your problem with them, they with a look into millions of millions of web pages from their database and display thousands of results. When you see those results you will understand that you not a unique creature on the planet with this problem. Many others faced this problem before you and posted on various tech support forums. Some kind peoples posted the solution as well to do blah blah blah and the problem will be shouted out.. but you are a computer lover. You are smart…

Will you also follow the same steps to fix the problem? without knowing what does this error means and why you are firing those bullets in form of commands from something called recovery console..

Well, If you are still reading and showing interest then this post is for you and I understands my efforts are not worthless. Read on. In this post, I will explain why and when does this error comes and what could be the possible reasons for this. Also how to fix it explaining why.. I will try to make it short but still, it may be a bit long..Take a deep breathe and continue reading …

NTLDR is Missing – When does this error come

Let me start from the beginning so it will make more sense..…

Power Button is pressed to power on the computer,
The SMPS supply power to all the components attached and then a PowerGood Signal is sent indicating Everything is OK to start booting,
The Executable Code in the BIOS ROM looks for the First Bootable disk in the configuration (Configuration is known as CMOS settings or BIOS settings in normal language however BIOS and CMOS are 2 different things which we talk on later.)
The BIOS looks for the first Sector of the Bootable Disk (Assuming your HDD is configured as a Bootable disk) and read it..First sector (Sector 0) of the HDD is called Master Boot Record and abbreviated as MBR.
The MBR contains 2 important parts, a small Bootable code, and the partition table.
The Small Boot code has the information to boot up the system and partition table contains a table of partitions and its physical location on your Hard drive.
The boot code Reads the partition table to find the active partition (Active partition is same as System partition which holds the core boot files).
Once successfully located, The MBR code transfers the control to the First sector of activating the partition.
The first sector of the active partition is known as the Boot Sector. Boot sector contains information about the partition layout, partition type, and a small executable code. The small executable does have enough capabilities to read the root of the partition (Only Files, not a subfolder or folder).
The BootSector (talking about Windows XP or Windows 2003) is designed to read “NTLDR” from the root of the active partition.
If the boot sector finds the NTLDR in the root, it handovers the next steps to NTLDR’s Entry point of the main function,
IF the boot sector is failed to locate NTLDR in the root of the volume, it will display an error message.
I bet now you know what will be the error message….
Oh!. You are right but… The error message text depends on the file system type. If its NTFS it will display “ NTLDR IS MISSING ” but in case of a FAT partition it will say Boot: could not find NLTDR

I hope you understood how this error comes..

OK, I got it, Now What can be done to fix it

After reading the steps above, it looks either of the blow is the possibility…

1. NTLDR is Corrupt or missing,

2. The Boot sector is corrupt or finding NTLDR at a wrong place,

Most likely first will be the possibility, to fix it –

1. Boot into Windows Recovery console. Windows recovery console comes with the windows installation CD.

2. Grab the CD and insert it into the CD drive (the coffee tray Smile )

3. Boot the system, It should boot directly from CD as almost all computers are configured to boot from CD first. It should ask you to “Press any key to boot from CD”

If not booting from CD then Configure the Computer to boot from CD drive. You should press Del or F1 or F2 to go into BIOS. Depends on the BIOS version and manufacture you will see Boot options. Change the CD as a 1st drive to boot from.

4. Windows Installation CD will load necessary files and ask you to choose one from below

5. Press R at this point

6. it will take you to the Recovery Console. Select the windows installation number. If you have only one OS then put 1.

7. Type the administrator password, if no password just press enter.

8. type “copy D:\i386\ntldr C:\” and press enter.

It should say “One file copied”.

9. Do the same copy for ntdetect.com as well which is supporting file for ntldr. Not needed but just to be safer side.

“copy D:\i386\ntdected.com C:\”

10. here, D is the drive letter of the CD ROM, You can find the drive letter by typing “MAP” command. It will tell you which is your CD ROM drive .or switch to each drive and do a dir. At this point, we can reboot and hopefully it should boot up the computer fine. If not then the problem was the 2nd possibility. the boot sector corruption. Why not apply both fixes together and reboot only once.

12. Let’s do the fix for this as well, it won’t harm anything, no side effect or running fix boot.

13. From the same command console, Do following.. Fixboot

Fixboot will repair the Boot sector and now you are ready to reboot the computer.

Restart the computer and you should see that the computer is happy to boot correctly…. That’s all for today, Feel free to write your thoughts, suggestion or if any questions in below comment box. It will help me improve this blog more and more for my readers…
