When you attempt to start Windows 2000 in a dual-boot configuration, you may experience any of the following issues:
This problem can occur if you are dual-booting Windows NT 4.0 and Windows 2000 and you installed Windows NT 4.0 after you installed Windows 2000, or if you have reinstalled Windows NT 4.0.
This behavior occurs because Windows NT 4.0 is unaware of the additional startup features of Windows 2000 and replaces the shared Windows boot files (Ntldr and Ntdetect.com).
To resolve this issue:
attrib ntdetect.com -r -s -hThis command may also be necessary from within Microsoft Windows 95, Microsoft Windows 98, Windows NT 4.0, or Windows 2000.
attrib ntldr -r -s -h
