Boot manager
Updated: 10/11/2017 by Computer Hope
A boot manager is a software utility for choosing what operating system to load from a list of operating systems installed on a hard drive. Not only can you choose between operating systems to load, but a boot manager can allow a user to boot to CD/DVD drives, floppy drives, or USB (universal serial bus) drives without needing to access the BIOS (basic input/output system).
