You will then need to edit the BOOT.INI file ; see this KB article on how to do that: http://support.microsoft.com/kb/323427/en-us(Windows Server 2003) http://support.microsoft.com/kb/289022/en-us(Windows XP) If you have OS and then want to dual boot with Windows Vista and/or Windows Server 2008 and you get into this problem you need to use a different tool called bcdedit from command prompt; KB article: http://support.microsoft.com/kb/919529/en-usand a Technet article: http://technet2.microsoft.com/WindowsVista/en/library/85cd5efe-c349-427c-b035-c2719d4af7781033.mspx?mfr=true BCDEDIT is a commandline tool but there are graphical tools created and posted on the internet (be aware that these tools are not created nor distributed by Microsoft). Do a Live search for "How do I edit boot menu" and you should find some nice articles and tools. Brjann
