BootCamp partitioning a Mac startup disk

by on August 3, 2009

Q: When I run BootCamp to install Windows on my Mac I get a message saying “Tthe startup disk cannot be partitioned or restored to a single partition.” How do I get BootCamp working so that I can install Windows on my Mac?

A: I think you might have left out a portion of the error message. I think the rest of the error message says “The startup disk must be formatted as a single Mac OS Extended (Jounraled) volume or already partitioned by Boot Camp Assistant for installing Windows.”

The reason you are getting this error message is because BootCamp is only created to work with the default system settings and that is having the  a single partition on your boot disk not multiple. So in order to get this to work you actually have to combine your partitions back into one and then BootCamp will be able to create a new partition for Windows and you should be ready to go.
