I need to install Windows on my Mac. I have read that I need to use Boot Camp to do this. However, when I tried, I got the following error on the first step:

The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.

The answer is simple. If you use Boot Camp Assistant, your start-up disk have only a single partition (i.e., do not partition the hard disk to reserve space for Windows by yourself). The Boot Camp Assistant will help you to do so.

Go to Disk Utility and delete those partitions, and then run Boot Camp Assistant again.
