NTLDR Problem

Hey guys, I'm new to dual-booting so I was wondering:

What can I do when I try to boot into XP and get an error saying that there was a problem booting this operating system. It also says that the windows directory on the XP partition is "\NTLDR". Also, my boot.ini files is as follows:
[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(3)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
