    Title says all. I've spent about an hour trying to figure out how to install Windows 7 on my 2012 MBA with USB (this is after making a post about why people have issues with BC...now I see why :rolleyes:) and after a brief search, someone said that the BRAND of USB used to make the boot disc from the ISO matters. I can definitely confirm that.

    I made the bootable USB through Boot Camp Assistant -- apparently there's a new option that allows you to make the USB from OS X.

    I first tried with a USB 3.0 Sony MicroVault Mach 16GB stick, but I kept on getting the non-bootable message.

    I then switched to a Sandisk Cruzer Blade 8GB stick, and that did bloody wonders.

    If there's anyone having issues with trying to make a bootable USB for installing Windows 7, try a different USB disc.

    Windows won't install via USB 3 even on PC's. Not sure with ivy bridge though since its native now.

    Definitely didn't work with the 2012 Air as it is IB.

    I don't have the air but I just used a 8GB HP and a 8GB corsair with no problems on a 2012 rMBP as seen in this video www.YouTube.com/diyallday

    I just used a Lexor 8GB USB3 Jumpdrive (even if it is still pretty slow) and installed Windows 7 on my 2012 Macbook Air and it worked ok?

    That's great, it is Ivy Bridge, so it may work now, I just know on PC's that are using the old NEC USB3 chip, if you put your thumb drive in the USB3 port it wont recognize it. I wasn't sure if Mac's were similar.
