boot camp startup disk cannot be partitioned

i installed ubuntu on a partition a while back. later i got bored so I deleted the ubuntu partitions using the live cd. Then I created a fat 32 partition(read it in a guide) after creating that partition i had to go into boot camp to restore the partition. when i open it says "The startup disk cannot be partitioned or restored to a single partition."

did i do anything wrong?

should i delete the fat 32 partition?

thanks
