Claim:
A method of insulating an operating environment emulator from a host computer, the method comprising: connecting a memory device to a host computer having an original operating system stored on a storage device of the host computer and a host processor, wherein the original operating system is executing on the host processor; selecting a secondary operating system to be emulated from multiple emulated operating systems stored on the connected memory device; selecting a secondary operating system emulator from a plurality of secondary operating system emulators, wherein the selected secondary operating system emulator comprises instructions configured to emulate the secondary operating system using the original operating system and the host processor; executing the selected secondary operating system emulator on the host processor and original operating system of the host computer; disabling host task management on the original operating system; insulating the original operating system from the secondary operating system by routing input/output signals through the secondary operating system; and disabling the secondary operating system in response to a breach of the insulated original operating system by an input/output signal being routed to the original operating system while the original operating system is insulated.
