Moono,
With Notepad, change your boot.ini so it matches this:
CODE
[Boot Loader]
Timeout=1
Default=multi(0)disk(0)partition(1)WINNT
[Operating Systems]
multi(0)disk(0)partition(1)WINNT="Microsoft Windows 2000 Professional"/fastdetect
This will give you a one second menu with the choice.
Note that this will not delete the Setup content. You can try and manually delete C:\WIN_NT$.~BT but since that is a special folder name, be careful not to remove C:\WIN_NT (or C:\WINNT).
Google "windows boot.ini" to get more information about the Windows Bootloader.
