I'm not so sure about that. The documentation Dave references is rather 
abstract, but I believe what it means in concrete terms is that you 
should generally use 'rootnoverify' for the partitions of "foreign" 
OSes, such as Windows. Such a partition may be unreadable by GRUB, and 
is presumed to have its own boot loader, so GRUB should pass control to 
that other boot loader at the earliest possible opportunity.

What could go wrong if you use 'root' instead? That's a good question, 
and I have no idea of the answer. But, as you can tell from the 
documentation, that command causes GRUB to *try* to mount the specified 
partition. Even if it doesn't usually cause problems in practice, that 
doesn't seem like a very good idea for Windows.
