CCBoot allows a diskless boot of either Windows XP, Windows 2003, Windows Vista, Windows 7, or Windows 2008 from an iSCSI target machine remotely located over a standard IP network. It's also known as network boot or lan boot. Diskless boot makes it possible for computers to be operated without a local disk. The diskless computer is connected to a hard drive over a network and boots up an operating system from a remotely located machine. CCBoot is the convergence of the rapidly emerging iSCSI protocol with PXE diskless boot technology. Thus it's also called PXE boot.
