Limitations

* Boot Camp will only help the user partition their disk if they currently have only a primary HFS partition, an EFI System Partition, and a Mac OS X Recovery Partition. Thus, for example, it is not possible to maintain an additional storage partition. A workaround has been discovered that involves interrupting the standard procedure after creating the Boot Camp partition, resizing the primary Mac OS X partition and creating a third partition in the now available space, then continuing with the Windows install. Changes to the partition table after Windows is installed are officially unsupported, but can be achieved with the help of third-party software. * Boot Camp does not help users install Linux, and does not provide drivers for it. Most methods for dual-booting with Linux on Mac rely on manual disk partitioning, and the use of an EFI boot manager such as
