You are the administrator of a Windows 2000 Server network. On each server, you format a separate system partition and a separate boot partition as NTFS.Several months later, you shut down one of the servers for the maintenance. When you try to restart the server, you receive the following error message "NTLDR is missing. Press any key to restart".You want to install a new NTLDR file on the server, but you do not want to lose any settings you made since the original installation. What should you do?

A
解析：Explanation: If the boot sector cannot find NTLDR, Windows 2000 cannot start. This can be caused by moving, renaming, or deleting Ntldr, corruption of Ntldr, or corruption of the boot sector. Under these circumstances, the computer might not respond to input or might display an error message. The Recovery Console can be used to restore the ntldr.exe file. This process would not create any other side effects.Incorrect answers:B: We cannot reinstall Windows 2000 as we do not want to loose any settings.C: System File Checker (sfc.exe) is a command line utility that scans and verifies the versions of all protected system files after restarting your computer. It cannot be used to restore the ntldr.exe fileD: Using File Signature Verification, we can identify unsigned files on our computer; however we would not be able to restore the ntldr.exe file.
