Make a NTLDR boot disk to get back into Windows.
The quick test to make sure your OS installation is still good is to create an MBR and NTLDR on a floppy disk and check if you can just boot back up into your system, this disk will check many of the partitions for a working windows installation. Here are the instructions to do this:
1. Get a blank floppy/cd-r/usb (whatever is on it will be erased), and put it into a working computer.
2. If you have a working Windows machine download my fix: Floppy fixntldr.exe | CD-R fixntldriso.zip | USB ntldrusb.zip onto a working computer (Backup copies of these files available at
http://ntldrismissing.com )
(What if I don't want to download a file from a website I don't trust?). (64 bit WinXP Floppy 64ntflop.exe | CD-R 64ntiso.zip | Files 64ntfile.zip)
Do you remember if the broken computers had the Windows installation in "Windows"? If you can't remember just keep going (What if it was not named Windows but WINNT like in NT4 or 2000?) .
(If your backup system is NT4 or Windows 2000: What if my backup system is Mac / Linux or another alt OS?).
3. Make the new boot disk:
*Floppy: Don't put the fixntldr.exe on your floppy drive, but the file on your desktop or anywhere on your C:\ drive. Run the fixntldr.exe file by double clicking it. Click OK to overwrite the blank floppy disc in the working computer, you should see some screens about writing a new floppy disk. (If you don't like running an exe from me, you can run fixntldr_RawRite.zip and just replace the RawRite.exe file inside with one you trust) (now go to step 4)
*CD-R: This is not a normal file you burn to a CD, it is an "ISO" file, you must first extract the fixntldriso.zip file by right clicking it and choosing "Extract All" then Next>Next>Finish then download a program called "ISO Recorder" from here
http://isorecorder.alexfeinman.com/isorecorder.htm (Windows 2000 users use Active ISO Burner IsoBurner-Setup.exe) and install it. Once it's installed, right click the fixntldr.iso file and choose to "Copy image to CD" or "Burn ISO file" and let it burn the cd (now go to step 4)
*USB: Right click the ntldrusb.zip file and choose "Extract All" Next>Next>Finish
Then Insert your USB Stick into the working computer (remove any other USB sticks, and be sure there isn't anything on the USB stick that you want since we are about to erase it);
Double-click HPUSBFW.EXE in the ntldrusb folder;
Check "Create a DOS startup disk" and "using DOS system files located at" then press the grey button with the "...";
A box will come up asking you which folder to select, point it to the "dos system files" folder;
Press OK; Press Start; Press Yes; Let it run for just a few minutes till a new box comes up; Press OK; Press Close;
Open the "putonusb" folder, copy all the files, paste them onto the usb stick (just in the root of the drive, like E:\);
Eject the USB Stick; Remove it from your computer;
Place it into the computer with the "NTLDR is missing" issue, reboot it.
You will see the Windows 98 screen pop up for a second, then you will see a black screen with white letters prompting you to "replace boot sector of the drive C: (y/n)", press the y key;
It will go to a C:\ prompt, reboot the computer by pressing Ctrl+Alt+Del; (now go to step 4)
4. Put the new floppy/cd-r/usb you have just created into the computer that gets the NTLDR is missing error message, turn the broken computer off.
Using the boot disk in the computer with the "NTLDR is missing" error.
Start back up the broken computer with the floppy/cd-r/usb inside it/plugged into it. Once your computer gets past the BIOS screen your computer should try to access the boot disk and you should see a black screen with white letters (What if I don't see this screen?). that says:
1ST TRY THIS seleccione esto primero
2ND TRY THIS essayez ceci en deuzieme
3RD TRY THIS wahlen Sie diesen Third
4TH TRY THIS selezioni questo fourth
5TH TRY THIS selecione este fifth
6TH TRY THIS seleccione este sexto
7TH TRY THIS essayez ceci en septieme
8TH TRY THIS wahlen Sie dieses achte
9TH TRY THIS selezioni questo nono
10TH TRY THIS selecione este decimo
(I threw in some Spanish / French / German / Italian / Portuguese for international flavor.)
This file is set up to automatically select the "1ST TRY THIS" choice after 30 seconds. Try it first, if it was the wrong selection, you will likely get one of these four errors:
1. Windows could not start because file "<Windows Root>\system32\hal.dll was missing or corrupt
2. Windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware. Please check the Windows documentation about hardware disk configuration and your hardware reference manuals for additional information.
3. I/O Error accessing boot sector file multi(0)disk(0)fdisk(0)\BO
OTSECT.DOS
4. Immediate reboot
If you get the immediate reboot or some other weird error, try pressing F8 at the "1st Try This" selection screen, it will give you a prompt where you can select Safe Mode, and then try the "1st Try This" option again. Safe Mode is a special "minimal" version of Windows that doesn't load certain parts of the operating system that might have caused the problem.
One of the choices should eventually boot you back into Windows.
