Restore from Time Machine after installing Bootcamp
No, Bootcamp will create a fysical partition on your Macintosh HD. If you restore your Mac  with TimeMachine, the software will only detect your Mac-partition and restore it's data. It will leave your Bootcamp partition in tact.

If you want to get rid of the Bootcamp partition, just run the Bootcamp assistant again and it will allow you to delete the Windows partition with one mouseclick.
