Will restoring from TimeMachine keep my bootcamp partition intact? I am going to install Mavericks from the scratch, formatting the Mac partition.
Then, using TimeMachine I will restore my data and applications.

The bootcamp partition was excluded from the TimeMachine backup. 

If I restore my copy with TimeMachine, will it keep intact the bootcamp partition as it was not backed up?

Thanks.
Yes it will.

As long as you only erase your Mac partition, the Boot Camp partition will be untouched. Time Machine will only modify the Mac partition.
