I have about 200GB of free space on my MBP. When I tried to install Bootcamp it said "startup disk does not have enough space to be partitioned. You must have at least 42 GB of free space available."

Why could my system have detected less than 42 GB when there is 200 GB left?
 
What size is the separate partition you’re installing to?

Without seeing your system overview, it could be that you do not have enough contiguous free space to install Boot Camp. You may have plenty of space but it might be scattered or the partition you're trying to install to is too small.

I didn’t make a partition yet of the internal drive. Are you supposed to do that first ? I thought that would be included in the process of setting up boot camp...
 
It sure helps if you tell us:
What year is the MBP?
What drive is inside?
What OS are you using?

Another thought:
Do you use time machine?
Could "local snapshots" be using up space?
 
Now my computer started in Windows but it's asking for "a valid Windows Product Key"
