A medical device comprises a software (SW) system for execution by processor(s). The SW system defines a plurality of subsystems, including a primary subsystem and one or more secondary subsystems, and each subsystem comprises SW applications involved in the operation of the medical device during a medical procedure. A deterministic and distributed startup of the SW system is enabled by separating the startup procedure into a preparation for startup on a subsystem level, by use of two different notifications, and a preparation for startup on a system level, in which the primary subsystem coordinates startup of the subsystems. The method comprises: initiating (401) each SW application; providing (402), by each SW application in the respective secondary subsystem when ready for startup, an ''application ready'' notification; providing (403), by the respective secondary subsystem when all of its SW applications have provided the ''application ready'' notification, a ''subsystem ready'' notification; and coordina
