Takeoff roll began normally on [Runway] 10R; upon rotation; the command bars immediately changed to the flight director; and at the same time; track mode changed to roll mode. The flight director was commanding a level off a few hundred feet above the runway; even though the altitude selector was set to 6000 ft.; the aircraft briefly entered magenta ALT hold a few hundred feet above the runway. As this happened; the auto-throttles then tried to roll back to maintain V2 + 10kts. (140 kts.) as though we were going to level off there. We immediately overrode the auto-throttles to continue the climb; then selected green flight level change and manual speeds at VFS. We changed LNAV and VNAV once at a safe altitude. During the brief cruise segment; just prior to descent we noted we had lost vertical PTH guidance/VNAV profile on both MFDs as well as both MCDUs. Fuel remaining at arrival; and ETA were also missing from the MFDs. We notified ATC we didn't have VNAV guidance and requested them to descend us. About 50 miles from destination; VNAV profile began working and we were able to resume the arrival as published.
Upon rotation on [Runway] 10R the command bars switched to the flight director. The lateral mode switched to roll and the vertical mode went to ALT. The auto-throttles retarded and the flight director was commanding level off. I manually pushed the throttles forward and pitched the plane to approximately 15 degrees up. I asked the FO (First Officer) for heading and flight level change. We went to manual speeds as the speed schedule was not sequencing either. Once at a safe altitude and on course we went back to LNAV and VNAV. Upon decent we did not have a VNAV profile and were unable to fly the STAR as published and received guidance from ATC. About 50 miles out of destination the VNAV profile populated.
E175 flight crew reported the loss of flight director presentations immediately after takeoff.
