About

Boot-US is a boot manager for starting existing operating systems independently on x86 machines. It supports BIOS and UEFI booting and can run multiple independent Windows systems. The package includes a graphical configuration program for Windows, plus command-line versions for Windows and 64-bit Linux. It works with MBR and GPT disks of any size, and includes tools to inspect partition details, hide partitions, and back up or restore whole disks and partitions. The site lists version 4.2.4, including a 64-bit Linux command-line version and a service to restore UEFI variables when Windows starts and shuts down. Password protection is available for the manager and configuration program, though some functions require a version 4 license. The non-licensed package is free for private PCs and public schools and may be tried for one month. Continued commercial use requires a license after the trial. One-PC licensing is listed at 24.50 USD per once.
