You can just pop a windows 7 install usb or use a usb optical drive to install windows like normal then you need to get the bootcamp assistant drivers from somewhere and install them so it can use the stuff for the air. You can also install OSX through internet recovery then bootcamp like normal. How to Re-Install OS X with Internet Recovery on a Mac

You can start the internet recovery reinstall process from either a shutdown Mac, or by rebooting the Mac. This process will be the same on any new Mac, be it an iMac, MacBook Pro, MacBook Air, etc:

Immediately after hearing the Mac boot chime, hold down Command+Option+R – if you see the Apple logo you waited too long and need to reboot and try again*
OPTIONAL: You may or may not see an option to join a wi-fi network, this depends on whether the Mac can access any saved networks from OS X or not.

Good luck.
