Hiding partitions, windows 2000 on second disk

[i22a]

When I type

hide (hd0,

and then press tab it lists 0 and 4 as possible partitions to hide. If I 
select 4, i.e.

hide (hd0,4)

it says Error this partion does not exist. ?? But anyway I worked around 
this by hiding the partitions using linux fdisk.

The reason I was doing this was because I want to get windows 95 on 
(hd1,0). However if I map this drive to (hd0), or if I hide all the 
partitions on (hd0) so that dos makes (hd1,0) drive c:, when I run the 
windows SETUP program it starts by doing a scandisk, and then crashes on 
the second check (I forget what it is). Windows won't install without 
doing a scan disk. How am I going to get around this problem?
