BZN ATCT called for release on Aircraft X and the aircraft was issued a release via the BOBKT2 departure; which was printed on the flight strip. Aircraft departed; was radar identified and appeared to be slightly off course. I asked the pilot if they were on the BOBKT2 departure and the answer was affirmative. Within 2 sweeps of the radar I could tell that the pilot was diverging from the BOBKT2 departure and I issued a low altitude to climb immediately through 10;500 Feet. The aircraft was at 8;300 Feet in an MVA of 10;300 Feet. The aircraft joined the departure East of the BZN airport. Flight conditions at the BZN airport were IFR and earlier PIREPs indicated IMC conditions at or below 12;000 Feet.
BOI TRACON Controller reports of an aircraft that is slightly off course and is below the MVA. Controller climbs aircraft and attempts to get aircraft on the correct course.
