Assuming you connected the positive terminals and negative terminals together on the jump, there shouldn't have been any harm done to the bike's electrical system or battery.
Take the battery to an auto parts store and have them test it. If the battery fails their test, replace the battery.
Next, check the main fuse, usually on the same cable as the positive battery connector. If the fuse is elsewhere, look for a 30A (or similarly sized) fuse in the electrical stuffs - usually under the seat or the general vicinity of the battery. If the main fuse is blown, replace it with the proper amp and voltage rated fuse - consult the manual as someone may have previously installed an incorrect fuse. If it blows again, troubleshoot the cause of the blown fuse (one spurious blown fuse is not a reason to troubleshoot).
Then check the fuses in fuse box, doing as with the main fuse if any are blown.
Lastly, verify the function of the main relay. I'm not sure where it is, so you may have to go digging in the bike's electrical schematics to figure out which one is the main relay and where that relay is located. You can test it by just figuring out which lead is the lead to close the relay (not the one that powers the loads when the relay is closed), and connect the battery's positive terminal to it. Just be sure to secure your test lead to the relay before attaching the other end to the battery - you don't want to short it to ground. If the relay fails the test, replace it. If the relay passes, check the continuity of the ignition switch.
