A method for starting an embedded apparatus, comprising: loading a fast start loader in a system image file by using a system boot program, wherein the fast start loader is configured to copy the system image file from a loading domain to an execution domain; running the fast start loader; loading, by the fast start loader, by segments according to service requirements of different services after running the fast start loader, one or more services corresponding to remaining image files in the system image file other than the fast start loader, and running the one or more loaded services, wherein the loading, by segments according to service requirements of different services, one or more services corresponding to remaining image files in the system image file other than the fast start loader, and running the one or more loaded services comprises: controlling the fast start loader to load a fast startup program segment in the system image file, wherein the fast startup program segment comprises a mission-critical service in the embedded apparatus; running the mission-critical service; controlling the fast start loader to load a non-fast startup program segment in the system image file, wherein the non-fast startup program segment comprises remaining services in the embedded apparatus other than the mission-critical service; and running the remaining services. loading a fast start loader in a system image file by using a system boot program, wherein the fast start loader is configured to copy the system image file from a loading domain to an execution domain; running the fast start loader; loading, by the fast start loader, by segments according to service requirements of different services after running the fast start loader, one or more services corresponding to remaining image files in the system image file other than the fast start loader, and running the one or more loaded services, wherein the loading, by segments according to service requirements of different services, one or more services corresponding to remaining image files in the system image file other than the fast start loader, and running the one or more loaded services comprises: controlling the fast start loader to load a fast startup program segment in the system image file, wherein the fast startup program segment comprises a mission-critical service in the embedded apparatus; running the mission-critical service; controlling the fast start loader to load a non-fast startup program segment in the system image file, wherein the non-fast startup program segment comprises remaining services in the embedded apparatus other than the mission-critical service; and running the remaining services. controlling the fast start loader to load a fast startup program segment in the system image file, wherein the fast startup program segment comprises a mission-critical service in the embedded apparatus; running the mission-critical service; controlling the fast start loader to load a non-fast startup program segment in the system image file, wherein the non-fast startup program segment comprises remaining services in the embedded apparatus other than the mission-critical service; and running the remaining services.
