dual booting with windows 2000

[cheesecake42]

Hi!
I'm setting up a dual boot with windows 2000 and ubuntu hardy heron but I now cannot boot into windows from grub. Windows was already installed and I set up ubuntu afterwards. Ubuntu resized the windows partition while I was setting it up. Here is my menul.st:

Disk /dev/sda: 40.0 GB, 40020664320 bytes

   Device Boot      Start         End      Blocks   Id  System

Have you tried rootnoverify (hd0,0) rather than root (hd0,0) or chainloader (hd0,0)+1 ?
