by running the Boot Camp installer again, assuming that you used Boot Camp to put Windows 7 on the disk.
On my macbook a 160gb hd, i previously ran Leopard on a 45gb partition and windows 7 pro on the rest. At the time i liked the macbook hardware and the ability to have both OS's. Now Enjoying Lion i have actually started using mac just as much if not more than windows but its currently installed on that partition. How can i delete my windows partition and extend my mac partition without having to reinstall lion?
