1. A method for booting a computing device to enable a software application to begin execution rapidly, comprising: detecting an indication to start operating the computing device; booting under control of a first operating system by a first processor system in response to detection of the indication; booting under control of a second operating system by a second processor system in response to detection of the indication, the second operating system booting more rapidly than the first operating system; beginning execution of the software application under control of the second operating system executed by the second processor system when the second operating system completes booting on the second processor system; and transferring control over the software application to the first operating system executed by the first processor system when the first operating system completes booting on the first processor system.
