The boot-loader is responsible to load the operating system kernel into the system memory, either from a hard-disk, via network or other media. After a successful load it passes the control of execution to the kernel - which in turn initializes the hardware and starts up system services including a possible user interface.

With modern T2 Linux versions the setup tool STONE should be able to setup the boot-loader properly and the system should boot into T2 Linux after the installation.

However there might be some platform where STONE is not yet able to configure the boot-loader or circumstances where custom adaptations is needed, for example when other operating systems should optionally be booted.
