linux and ez-drive

I have Mandrake-linux ver. 5.x? installed on a hard drive that was set up with ez-drive. I want to change the master boot record so that it doesn’t go to lilo and boots to windows only. I’m not going to use Linux any more on this machine. I remember that you can’t use the fdisk /mbr for this but can’t remember what the procedure is. Can anyone help?

Thanks in advance.
