Narrative:

During initial climb; the 'gear disagree' and the 'nose door open' warning messages was displayed on the EICAS. The nose gear showed dn (down) and the main gears showed up. The pilot not flying performed the non-normal checklist. While performing the non-normal checklist there was a little confusion on what scenario to choose. The gear up disagree was performed; then the gear down disagree was also performed. After performing both scenarios the landing gear showed down and locked and the flight returned for a normal landing. The event occurred because the nose gear did not retract. There was confusion about what scenario to choose because the indication in the checklist did not match up with the indications on the EICAS. The checklist said the landing gear (box) symbols should display red; but it displayed up and dn on the EICAS.
