Does anybody knows how to install Windows 7 from a USB drive on 2010 MacBook Air running Lion?

Pick one, any one.

Tell my wife that!😉

This is the best I can do. This way you can use the 2011 MBA way to do things.

Look forthe postfrom @jacktourist. (on page 2 about half way down) This seems to be the easiest.

There are a couple of more similar to this with pictures I've seen around but can't remember where.

Here's another search with added info. It's easier then it sounds.
