I've got a similar problem. I can use Windows normally, but not Android. I tried installing with this method.
Instead of one, I have three "Android-IA" options when pressing F7.
No matter which one I press. Some times I get the "Intel inside" logo forever. I have to restart.
Sometimes it shows the intel inside logo, and then starts with the "Android is starting...", and below "Optimizing app x of 84". And finally, it changes the optimizing part and stucks on "Starting apps.". I have to restart, no matter how much I wait.
And sometimes it just reboots a few times until I get in one of the other two options.
I tried with the "just android" (destroying Windows), but the USB does nothing.
And tried reinstalling this USB a few times, no luck either.
