Hi

When I turned on our computer this morning I was greeted with

NTLDR is missing press ctrl>Alt>Del

I have read a little information on this, and tried to Repair using full original of Windows XP disc however all goes well until I get to where the CD is asked to be inserted >press enter, I do this and get " Setup could not read the CD you inserted, or the CD is not a valid Windows CD". This is the CD that windows was loaded on to this computer with sometime ago.

Help, wht can I do.

Many thaks

Is the CD damaged? Scratched?
If not, this might be worth running for a few hours:

When you usually see the message NTLDR is missing its because either you have no Hard Dtive connected or Bios cannot find any boot record on it.

Does your hard drive appear in your Bios setup menu?

If not then either it is not connected properly or your hard drive is broken

if it does then you probably have a corrupt boot record on it so the Bios cannot recognize you OS install on it and cannot boot.

As for not being able to read your XP cd did you put your cd-rom as your first boot

also some bios asks you specifically which cd rom (if you have two) you will boot from while others will search on both automacally without having you to specify.

So check in your BIOS the order of boot and if you have to specify which cd rom to use as boot or not.

If you have Windows CD...

1. Insert your Windows XP CD into your CD and assure that your CD-ROM drive is capable of booting the CD.
2. Once you have booted from CD, do NOT select the option that states: Press F2 to initiate the Automated System Recovery (ASR) tool.
You’re going to proceed until you see the following screen, at which point you will press the “R” key to enter the recovery console:

3. After you have selected the appropriate option from step two, you will be prompted to select a valid Windows installation (typically number “1").
Select the installation number, and hit Enter.
If there is an administrator password for the administrator account, enter it and hit Enter (if asked for the password, and you don't know it, you're out of luck).
You will be greeted with this screen, which indicates a recovery console at the ready:

4. There are eight commands you must enter in sequence to repair any of the issues I noted in the opening of this guide.
I will introduce them here, and then show the results graphically in the next six steps.
NOTE. Make sure, you press Enter after each command. Make sure, all commands are exact, including "spaces".
These commands are as follows:

CD..
ATTRIB -H C:\boot.ini
ATTRIB -S C:\boot.ini
ATTRIB -R C:\boot.ini
del boot.ini
BOOTCFG /Rebuild


Note about the above command.
BOOTCFG /REBUILD command which searches for pre-existing installations of Windows XP and rebuilds sundry essential components of the Windows operating system, recompiles the BOOT.INI file and corrects a litany of common Windows errors.
It is very important that you do one or both of the following two things:
A.) Every Windows XP owner must use /FASTDETECT as OS Load Option when the rebuild process is finalizing.
B.) If you are the owner of a CPU featuring Intel’s XD or AMD’s NX buffer overflow protection, you must also use /NOEXECUTE=OPTIN as an OS Load Option.
For the Enter Load Identifier portion of this command, you should enter the name of the operating system you have installed.
If, for example, you are using Windows XP Home, you could type Microsoft Windows XP Home Edition for the identifier (it's not crucial, however what the name is, as long, as it's meaningful).
Here is your computer screen:

5. Following command verifies the integrity of the hard drive containing the Windows XP installation. While this step is not an essential function in our process, it’s still good to be sure that the drive is physically capable of running windows, in that it contains no bad sectors or other corruptions that might be the culprit:

CHKDSK /R

6. This last command writes a new boot sector to the hard drive and cleans up all the loose ends we created by rebuilding the BOOT.INI file and the system files. When the Windows Recovery Console asks you if you are Sure you want to write a new bootsector to the partition C: ? just hit “Y”, then Enter to confirm your decision:

FIXBOOT

7. It’s time to reboot your PC by typing
EXIT
and pressing Enter.

With any luck, your PC will boot successfully into Windows XP as if your various DLL, Hive, EXE and NTLDR errors never existed.




Thanks To Broni For The Instructions

Where exactly do you get this message?
Is the system booting to the cdrom or is it still booting to windows?
You may have to go into the bios and set the boot sequence so that the cdrom is the first boot device. Let me know if you don't know how to do this and i will supply instructions.

Hi

Thanks for your reply.
The system doesn't seem to be loading windows. It loads the Intell (whatever) then a few seconds later I get the message NTLDR is missing press ctrl>Alt>Del

I then tried to boot using the windows os disc, didnt work, so.
I went to Recovry etc on the win os cd.

I get the message when I move through the Windows CD trying to use recovery ® on the CD.

Hope this makes sense. Can you help me make a boot disc.

Many thanks

To change Boot Sequence in your BIOS
Reboot the system and at the first post screen (where it is counting up memory) start tapping the DEL button
This will enter you into the Bios\Cmos area.
Find the Advanced area and click Enter
Look for Boot Sequence or Boot Options and highlight that click Enter
Now highlight the first drive and follow the directions on the bottom of the screen on how to modify it and change it to CDrom.
Change the second drive to the C or Main Drive
Once that is done then click F10 to Save and Exit
You will prompted to enter Y to verify Save and Exit. Click Y and the system will now reboot with the new settings.

Hopefully you have already put the XP cd in the drive before all this. If everything is setup correctly you will get a black screen with the following message in the upper left corner:
"Push Any Key To Boot To Cd". When you see this then push any key and the cd will take over. Then follow the prompts from the long post I gave to do the steps or if you need assistance we will help.
