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. It can also chainload GRUB, LILO and NTLDR. However, being independent of an OS prevents it from being able to boot any disks which are not accessible via BIOS I/O routines (e.g. INT 13H), with the exception of BeOS disk-in-a-file images on FAT32, NTFS or ext2 file systems.
== Configuration == In Haiku, BootManager exists in "/boot/system/apps/BootManager".

7. Draw to adjust the timeout and select the default OS that loads when the timeout finishes.
