Windows 7 Multi boot xp-vista-win7-mandriva2008 w/grub

[sledd58]

I have xp installed on a sata drive 0 Partition 0
I have vista installed on ide drive 0
I have mandriva installed on ide drive 1
The grub mbr is on sata drive 0 partition 0 and boots all three
Boot Mandriva
Boot Windows-XP
Boot Windows-Vista

Now I installed Win7 on sata drive 0 partition 1
but win7 boot mgr attaches to vista on ide drive 0
So if I point grub to sata drive 0 partition 1 to boot win7 it errors
if I boot vista I get the dual boot option vista or win7

If I unplug the ide drives and do a fixboot /fixmbr
then it attaches to xp on sata drive 0 partition 0
Same error to boot win7
Now boot xp and get the dual boot option

So is there a way to keep win7's boot mgr on win7's partion with out messing with the other partitions
so I can get Grub to boot win7 like the rest
