EasyBCD vs OpenCore

EasyBCD is a Windows bootloader editor for setting up multiboot systems and changing boot menus. It can configure systems involving Windows, Linux, macOS, and BSD, and boot from USB drives, ISO images, and virtual disks. Users can add, rename, remove, configure, and reorder boot entries, including entries for recovery utilities or safe mode. The tool can back up and repair a bootloader, and its NeoGrub scripting can hide partitions, change active flags, and support complex boot setups. EasyBCD supports BIOS and UEFI. Personal, non-commercial use is free; the Commercial plan costs $39.99 as a one-time purchase. NeoSmart advises care when modifying boot settings and says EasyBCD cannot fix a PC that will not boot, directing users to EasyRE for that situation. The latest release listed in the changelog is version 2.4.0.237, dated November 28, 2018.

OpenCore is a bootloader distributed with a development SDK. Its repository includes UEFI support libraries for Apple-specific UEFI drivers, with support for loading Apple disk images and manipulating PNG images. The libraries also cover Apple PE image signature verification, supplemental Apple UEFI secure boot code, XNU kernel driver injection, and a patch engine. For configuration, they parse plist files; OcGuardLib provides safe integral arithmetic, type-alignment checks, and a UBSan runtime. The project lists UEFI and BIOS support, multiboot, boot-entry editing, and boot-menu customization. It is described as multiplatform, with Linux, macOS, Windows, and self-hosted among the listed platforms. OpenCore is free and open source under the BSD-3-Clause license. Release source archives are available as zip and tar.gz files, including version 1.0.7. The README points users to discussion forums in several languages, including KVM configuration discussion. Documentation also lists third-party kernel extensions and says that list is informational and provided without warranty.
