Systen Testing can be limited upto functional as well as non functional testing of the System, but when we talk about end-to-end testing, all the interfaces, sub-systems must come into picture.  All the end-to-end scenarios should be considered and executed before dployment of the system into actual environment.

System testing - black-box type testing that is based on overall requirements specifications; covers all combined parts of a system.

End-to-end testing - similar to system testing; the 'macro' end of the test scale; involves testing of a complete application environment in a situation that mimics real-world use, such as interacting with a database, using network communications, or interacting with other hardware, applications, or systems if appropriate.

End-To-End Testing refers to User Level testing of Component based systems. It verifies that the integrated component functions correctly as part of the overall system, and the existing Components of the System work as before. End-To-End Testing approaches the system from a Functional Side and the Architecture side, thus combining Black-Box and White-Box Techniques. The Steps required to perform End-To-End testing include Test Design, Test Execution and Test Results Analysis

System Testing: Testing the core functionality of a component or system or application.

End-to-End Testing: An application may have dependency on upstream or downstream system or application. Testing the complete flow of data on all the components or application is called E2E testing.
