NTLDR missing

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

Does this also work on a Lsass.exe application error?

It might fix it but not sure if that will have to be done at a different time. I see you have 3 topics open.
Are they all for the same system as something we do in one may nullify something done in another.

I have 3 computers with problems. 2 were mine and the other one I returned. But I haven't heard from the tech helping me on this LSASS.exe for a few days, and thought maybe you could tell me something different.

Thanks!

Send The Skeptic a message as he may be busy and just not been able to get back. He will get a email notification on it.
Have you tried what I suggested to fix this system?

No, I have not tried it yet. Not sure if you read the discussion on the Lsass.exe, but I can't get the Avira Rescue to finish loading to see if I have a virus, I don't think that it is a virus, which is why I was wondering if I do do the above, will it work? I will try, but if I do what you suggest above, what's the worst thing that can happen? I get a different error message, and I'm back here looking for answers. Right?

The worst thing is the system still will not boot up.

Hi again, well, your suggestion, I couldn't do. It wouldn't load the XP cd. So, I downloaded the Kaspersky Rescue, and it read and scrolled thru computer, but now i get a blue warning screen. Operating sys has been shut down incorrectly. File sys is going to be mounted. the procedure may cause damage to it. to avoid file syst corruption, you are advised to shut down the oper sys correctly before using kaspersky rescue disk. do you wish to continue? continue, skip or restart comp?

I'm afraid to continue it, what could happen. I cannot loose my data on my hard drive.....please advise!!

thanks!!

Restart as that is the safest way. Since it has that option chose it and the system should restart on it's own.
Let me know what happens and we may have to try some other steps.

Well, I did choose the restart computer, however, it went back to the same state of blank screen. Going to try another rescue cd to see if maybe it will work.

Oh, by the way, on my other computer I have an NTLDR is compressed. Will your suggestion still work the same if the error was NTLDR is missing?

Thanks!!

It didn't work as you said does that ean you ran the steps or did the system not boot up to the screens described in my instructions?

LSASS.exe failure computer: I ran the Kaspersky CD, it ran thru what it needed to, and then I got the warning screen, and while I waited to see your response if I should go forward and risk overwriting stuff I might have regretted, I went ahead and opted to restart computer. It restarted, but I still got the LSASS.exe error message. My winXP cd will not load, and I do have my BIOS setup correctly to start CD, and I hear it spin, but it doesn't respond to my press any key, and it continues to load windows, but then all that comes up is the LSASS.exe application failure. I know the BIOS is correct, because I was able to load the Kaspersky CD, and the Avira Rescue CD loads too, but it just freezes at the penguin screen, which is probably because the computer has not shut down properly.

Then lets make sure the data is safe before we proceed.
Get Puppy Linux from my signature below...Get puppy-2.16-seamonkey-fulldrivers.iso download it and burn it to cd
..
if you don't have a burning program that will burn .ISO files get Burncdcc from my signature...it is a small FAST no frills iso burning program...

NOTE...do not put a blank cd in until burncdcc opens the tray for you
1. Start BurnCDCC
2. Browse to the ISO file you want to burn on cd/dvd ....in this case its puppy-2.16-seamonkey-fulldrivers.iso
3. Select the ISO file
4. click on Start

make sure in the bios the cd drive is the first boot device....

put the cd in the cd drive..boot your computer....puppy will boot and run totally in ram...if your hardware is is good working order you will know...
after you get it running and your at the desktop...you take the puppy linux cd out and then you can use the burner to copy all your data to cd/dvds
you can also use it to backup your data to a external usb harddrive..just have it hooked to the computer when you boot up with puppy...

==========================
quick guide for saving data...music..files on a system that will not boot using puppy Linux..


after you get to puppy desktop..
click on the drives icon...looks like a flash drive...top row..it will list all the drives connected to

your computer...

click on the red icon for the drive you want to mount...in this case its a flash drive ...puppy will

mount the drive..the drive icon turns green when its mounted...
minimize the drives mounter window..you will need it again in a few minutes..
drag the right edge of it sideways to shrink it to its narrowest size...about half the width of the screen...then drag the window to the right edge of the screen...

now click on the icon that looks like a filing cabinet (kind of yellow) on the main drive...it should
already be green..
you will see a list of all the folders on the main drive Usually your C: drive..shrink that window to
the narrowest you can..about half the width of the screen...drag that window to the left side of the screen...
at this point you should have 2 windows open on your desktop..the flash drive on the right side..
go back to the folders on the C: drive...click on the documents and settings folder...then your user
name or all users..find the folders that has your data..
drag and drop the folder with the data you want to make copies of to the flash drive window...

your options are to move ..copy ect...JUST COPY..if its to big you will have to open the folder and
drag and drop individual files until the flash drive is full...(I have a 120 GB external USB drive for
big data recovery jobs and a 4 GB flash drive for the smaller jobs)..after you get the files copied to
the flash drive...
Click on the drives mounter you minimized earlier
UNMOUNT THE FLASH DRIVE by clicking on the green icon..you will once in awhile get error messages when
unmouting the drive..ignore them..when the flash drive icon turns red again its safe to remove the
flash drive..trot on over (stroll if you want to look cool) to another computer and plug in the flash

drive and copy all the data files ( I drag and drop) to the other computer..
make sure the other computer can read them...

now delete the data on the flash drive...take it back to the misbehaving computer and plug it in

again..click on the drives icon again and repeat until you have all your data transferred to the working
system..

Thanks to happyrock

Hi again, I just wanted to ask about the NTLDR now. My topic started out how to fix a NTLDR is missing, however, I made a mistake. It says it's actually compressed. If I follow the same instructions above, will it work for the compression? This computer has a few trojans in it which I had the Avira CD take care of for me. Now the next step is to fix the compression.

Thanks again!!!
