BootManager, formerly known as BootMan, is the Haiku and BeOS boot loader on x86 systems. It resides solely in the master boot record and does not require installing Haiku or BeOS, although it must be installed from Haiku or BeOS. Its BeOS predecessor was BootMan, and was later renamed as BootManager by the Haiku project.It is filesystem agnostic, and boots an operating system as if it were being booted directly from the hardware. As such, it can boot virtually any operating system.
