GRUB boot loader problem

I had a laptop that was dual booting redhat 7.2 and windows 2000 with GRUB. 
I deleted my linux partitions to gain back the total drive space for 
windows2000, but now grub wont load windows2000. How can I get my 
windows2000 to load now? when I try to boot up I get a message that grub 
provides minimal BASH terminal commands. I typed help to see the commands 
but I cant figure out what to do next.

THANK TO ANYONE OUT THERE WHO CAN HELP OUT, IN ADVANCE.

Best,

Dane
