I have boone as my follower and i loaded my game and he was nowhere to be found. anybody know what to do?

Check and see if you still have his perk, if you do then he's still alive and will probably come back after some traveling and entering/exiting locations, if you don't then he could be either dead or just back in novac (I think that's where he's from)

I still have his perk, and iv tried fast traveling. :nope:
