Grub and Windows on Logical Disk

[Wolfgang Machert]

Hello,

although I think that this would have been asked several times before, it is my 
hope to get some info on this.
I wanted to boot Windows and Dos from a Logical Partition - the news release of 
version 0.90 announced Grub beeing able to do so.
Though i wasnt able doing this.
My Configuration:

hda1    Linux Swap
hda2    Linux Ext2
hda3    Linux Ext2
hda4    Windows Fat32
hda4    Windows Fat32

On each partition is a different OS.

Thanks in advance
Wolfgang Machert
