NTLDR stands for NT Loader, a program which helps Windows NT/NT-based systems load. Sometimes this file gets corrupted or goes missing and you can't boot up your system. What to do?
Well in theory this is a simple thing to fix. Just follow along.
First off, sometimes, if you were installing another operating system or fooling around with your BIOS settings, then the system tries booting up to the wrong drive. Make sure you don't have any disks (such as CDs or floppies) in your computer when you are trying to boot up.
If it still doesn't boot up, check your BIOS settings to make sure that it is not trying to boot up to another hard drive, which might have an incompletely installed version of Windows, or some other problem. Make sure that out of all the hard drives, the one with the system tries to boot up first. Check the jumpers on your hard drives' manuals to set the one with the system to Master and the other(s) to Slave.
Another reason may be that the drive cables are loose. Try pushing (not forcing) them in a bit.
If that fails, follow these steps (Windows XP, maybe works with 2000, haven't tested and am NOT liable to any problems that are caused if you try this on 2000):
1. Put your Windows XP installation CD into the computer.
2. When the screen says "Press any key to boot to CD..." press a key. If you do not see this message, then check your BIOS settings to make sure that it tries booting to the CD-ROM drive before the Hard drive.
3. Wait for the setup program to load. When it is finished, press the "R" key on your keyboard to repair your installation of Windows.
4. You might have to select your installation of windows. (If your installation of windows is set as a drive other than C:, turn off the PC, disconnect all other drives other than the system drive, and repeat steps 1-4.) Select the correct one.
5. If you set an administrator password, you will have to type it now.
6. Type the following commands and press enter after each one, where X: is the drive letter of your CD-ROM drive:
copy X:\i386\ntldr C:
copy X:\i386\ntdetect.com C:
7. When you are done, take the CD out of the drive, and reboot.
You should be able to boot up now.
I am not liable for any damages caused after following these instructions, nor do I currently have the ability to provide technical support.
