Clover Bootloader vs Petitboot

Clover Bootloader starts macOS, Windows and Linux systems on Macs and PCs with UEFI or BIOS firmware. It can launch through UEFI directly or use CloverEFI to emulate UEFI, and supports UEFI and legacy boot modes. Its graphical interface can be customized with themes, icons, fonts, backgrounds, animations and mouse pointers. Users can create boot entries for other operating systems, while the interface can save preboot logs, screenshots and OEM ACPI tables for diagnostics. Settings are held in an XML config.plist file in EFI/CLOVER. When firmware Secure Boot is enabled, Clover’s Secure setting limits booting to signed binaries. The repository links to a separate theme manager and theme collection, and its README points users to AppleLife, InsanelyMac and macos86.it forums. Build procedures are provided for macOS and Ubuntu 19.10. Clover incorporates OpenCorePkg libraries for kext injection and patching. It is free under the BSD 2-Clause License, which permits source and binary redistribution. The releases page lists version 5175 as latest, with six assets.

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.
