Boot Camp is a software assistant made available by Apple Inc. that assists users in installing Microsoft Windows XP Service Pack 2 Home or Professional, or Windows Vista on Intel-based Macintosh computers. Boot Camp guides users through non-destructive re-partitioning (including resizing of an existing HFS+ partition, if necessary) of their hard drives and creating a CD image with device drivers for Windows. In addition to device drivers for the hardware, the CD includes a Windows control panel applet for setting the primary operating system.
