I have the same problem. Here are my boot.ini entries:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS.0="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /Execute /fastdetect
Which of the two should I delete? And is there a clue to identify which one is to be deleted? The only difference I see is that the first one says "noexecute=optin" and the second one says "Execute." Does that mean something?
Thanks for your help
