Another way to find it is with the old dos attrib command, eg attrib boot.ini /s (at command prompt).
Also if you have trouble editing it,you can use attrib boot.ini -a-h
as somtimes it is easier to change file attributes through dos for the purposes of W2K.
-r takes off read only
-a takes off archive
-s removes the system attribute
-h removes hidden

+r adds read only,etc

attrib is located in c:\winnt\system32 which should already have a path to it. If for some strange reason not, then Path=c:\winnt\system32 shall do it.
