Listen to what everyone is basically saying. Don't get anything valuable for your first year(s). Get a POS walmart bike or old road bike and be done with it until later. Then with a suitable place to store your trusty steed, spring for a decent one worth worrying about.
I just realized, however, if your dorm allows it (probably won't) and if your roommate doesn't mind (probably won't), then you might be able to store the bike in your room (which probably doesn't have enough space). And if you did (which you shouldn't), you would still have to keep it locked just as well there, since there are just as many thieves inside the dorm as there are out. Good luck!
