    rEFInd

    rEFInd

    An EFI boot manager utility

    rEFInd is a fork of the rEFIt boot manager. Like rEFIt, rEFInd can auto-detect your installed EFI boot loaders and it presents a pretty GUI menu of boot options. rEFInd goes beyond rEFIt in that rEFInd better handles systems with many boot loaders, gives better control over the boot loader search process, and provides the ability for users to define their own boot loader entries.

    Rufus

    Rufus

    Utility to create bootable USB flash drives

    Rufus is a standalone app designed to format and create a bootable USB drive for a large variety of ISOs. The app is just over 1MB in size and is notably faster than similar competitor apps such as the Windows 7 USB utility, Universal USB Installer, and UNetbootin. Rufus can come in handy when you need to simply format a USB drive, install an OS on a machine that lacks a CD/DVD-ROM drive, or when you need to boot an operating system temporarily without intentions of actually installing the media. This can be immensely useful while you're on the go or just need access to an OS for a temporary, isolated reason. The app can even be used to flash firmware to BIOS or other destinations by just using DOS. Even though Rufus is a tiny utility in comparison to other USB creation tools that can be rather bulky in size, it contends easily with the competition and creates bootable USB drives in record time!

    MacUSB

    Creating bootable macOS and OS X USB drives has never been easier

    macUSB is a macOS utility that streamlines the creation of bootable USB installers for macOS and legacy OS X versions, taking the complexity out of preparing installation media on modern Apple Silicon or Intel Macs. It automates disk formatting, installer detection, and content writing so that you can revive or install operating systems on older hardware—something that has become more difficult since Apple’s transition to its own silicon. With support for handling various disk image formats and applying necessary fixes for installers with older certificates, macUSB demystifies what was once a command-line-intensive process. Its goal is to make preparing bootable media accessible to users of all skill levels by intelligently managing installer images and systems, giving Mac users a straightforward path to restore or reinstall macOS across generations.
