Why, of course It just doesn't have the same running capabilities.
I have the ISO of windows 7 on my desktop, just need to go the further mile and figure out how to run bootcamp with it. For now, i'm OK with having a virtual windows 7.
Unless you're on a MacBook Air, you should have disc burning capabilities. If you don't have any blank discs, find a spare 4GB USB drive. Bootcamp should come preinstalled on all Apple machines. And if you don't have your OSX disc, it should prompt you to download the necessary Windows drivers.
Honestly, Bootcamp walks you through every step. It's incredibly easy. I'm fairly certain Parallels is also compatible with Bootcamp, allowing you to run the installation as a virtual machine if you're too lazy to reboot for a specific application.
