A fault tolerant operating method and an electronic device using the same are provided. The method includes: performing a first procedure by a first executive file installed in the electronic device; when an error occurs to cause the first procedure to abort, sending an aborted notification to a fault tolerant module by an operating system (OS) and obtaining an aborted address information of the first procedure by the fault tolerant module; and sending the aborted address information to the OS by the fault tolerant module, such that the OS calls the first executive file to continue executing the first procedure based on the aborted address information.
