I obviously do not have a CD/DVD in my MBA so I need to install from a flash drive. When I go into bootcamp, the option: Create a Windows 7 install disk is greyed out. WTF? I was able to create a bootable copy of Win7 on my flash drive using the "Windows 7 USB/DVD Download Tool" but with the USB stick inserted, it gives me an error: The installer disc could not be found. Any help is greatly appreciated.
