About 30 minutes after takeoff we got a Right Generator Warning with R GEN CONT light. The Captain ordered that I continue flying and talk to ATC and then started the APU and took the QRH. He read the name of the checklist and about that time; when the APU took over the associated bus; we had an auto pilot disconnect. I switched to hand flying and connected to another autopilot. After that distraction--which caused the Captain to look up and then go back to the QRH--he went to the other checklist on that page--the one for generator drive disconnect--and started doing the items from that list. The moment he disconnected the generator drive he realized the mistake; but the generator was already disconnected. We continued with one [engine driven] generator and [the APU generator]. Our destination weather was clear. [We] landed with 13;600 LBS of fuel. The R GEN light was on all the time until it was disconnected; so we definitely had a generator problem.There is one very important lesson to learn from this experience: ALWAYS match the EICAS annunciation with the title of the checklist in the QRH to avoid unnecessary mistakes like this one.

Following accessing the appropriate QRH in response to an EICAS R GEN warning and an illuminated R GEN CONT light; the Captain of a B767-300ER was distracted by a momentary autopilot disconnect and then performed the wrong QRH procedure found on the same page; the generator disconnect checklist. After realizing the error they elected to continue to destination operating with the left engine driven generator and the APU generator.
