In their own words
Boot-US
Boot-US is a boot manager for x86 machines that lets you start existing operating systems independently, including multiple separate Windows systems. It supports both BIOS and UEFI booting and works with MBR and GPT disks of any size. The package has a graphical configuration program for Windows and command-line versions for Windows and 64-bit Linux. It also includes tools to inspect partition details, hide partitions, and back up or restore disks and partitions. The site lists version 4.2.4, including a Linux 64-bit command-line version and a service for restoring UEFI variables when Windows starts or shuts down. SHA256 values are listed for that version’s downloads. The non-licensed package is free for private PCs and public schools, and can be tried for one month. Commercial use requires a license after the trial. Listed licenses are one-time payments, starting at €24.50 for one PC; some password protection functions require a version 4 license. The license page says the software is provided without warranty and used at the user’s own risk.
Petitboot
Petitboot is a free, GPL-2.0-licensed bootloader implemented by userspace programs in a small Linux image. It discovers devices and bootable images, reads configurations such as GRUB, SYSLINUX, and Yaboot, then starts systems through Linux kexec. Its primary interface is an ncurses menu for viewing boot choices and system information, changing settings, running plugins, and opening a shell. Operating-system images can be loaded over HTTP, HTTPS, NFS, SFTP, or TFTP. Basic functionality is available on platforms that support kexec, while documented platform implementations include POWER systems using OPAL firmware and ARM64 systems with efivarfs support. On supported systems, inband IPMI can report BMC information and alter boot behavior through boot-device overrides. Plugins package and run binaries and may be discovered locally or in PXE network files. The pb-discover server finds and configures devices, while user interfaces communicate through pb-protocol. The included pb-sos utility gathers diagnostic and crash information.
