I have my MBA 2013(i7 and 8gb RAM upgrades) and I am working to install Windows 8.1 to bootcamp. From there I will make the bootcamp partition bootable from VMware Fusion. This is necessary for work, because this is my work laptop and there is occasionally some instances I need to run a native Windows experience in order to do my job. After the last EFI upgrade I was able to install it just fine. However, upon going back to the bootcamp assistant in order to create my driver disk, I get the error that "The Startup Disk could not be restored to a single partition". Upon going to the Disk Utility, It shows that my bootcamp partition is okay and I have another partition listed as "disk0s3". Please help.
