Dual boot Win2K and Win-ME

I installed Win ME on my second partition, and am now trying to boot it with the ntloader. W2k resides on c: (fat32) and Win ME on d: (fat32)
My boot.ini looks as follows :

[Boot Loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[Operating Systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT=”Microsoft Windows 2000 Professional” /fastdetect
c:\=”Microsoft Windows Millennium Edition”

On booting Win ME I get : BOOTSECT.DOS I/O error 🙁

Any ideas ?
TIA,
Dirk
