This is a standard negative prefixation of 'efficient', and the meaning 'not efficient' is directly predictable.

Etymology

The word inefficient is made of the parts in- 'not' and efficient 'working well' or 'doing a job without waste'. So inefficient describes something that does not work well and wastes time, effort, or resources.
