Just taken delivery of my lovely new MacBook Air and need to install Windows 7 on it for the odd bit of home-working, but despite following all the documented instructions on how to do it, I end up getting stuck when trying to install Windows on the Bootcamp-created partition. I've got a Win 7 Ultimate ISO file (which does work 'cos I've installed from it before on a Wintel box) which Boot Camp Assistant uses to create the bootable install on an 8GB USB flash drive, and all goes fine until the actual installation of Windows 7, when I get an error saying that Windows can't be installed to the Bootcamp partition. Here's a screenshot of the install screen: I've tried choosing the Format option that you can see in the screenshot but that doesn't make any difference. Has anyone else encountered the above issue? If so how do you fix it?
