I have recently switched from PC to Macbook. Im not very familiar with the Mac features but i've managed to figure out everything through online except for one. Before i purchased the Macbook at the Apple store, the guy told me that i can run Window on the Macbook but he told me that i would have to turn off the macbook and restart with the Window. How do i do this? I've been trying to use the Window but i still can't find the way to do it.
