go to the command prompt and go to the root of c:
type:
attrib boot.ini -r -h -s
and then
edit boot.ini
you'll see the boot config for win2k and windows.
delete the line for windows. should be something like c:\bootsect.dos = "windows" or something like that.
then, u can go back and delete the file that was on the line. in this case, it would be bootsect.dos
