A bootloader is a type of software that manages the loading of the operating system (OS) on the computer at startup. It is responsible for preparing the system before passing control to the OS. Here are the types of bootloaders commonly used in NixOS:

* '''GRUB (Grand Unified Bootloader)''': Widely used, supports multiple operating systems, and provides a boot menu to select how the system boots.

* '''[[GNU GRUB]] (Grand Unified Bootloader)''': Widely used, supports multiple operating systems, and provides a boot menu to select how the system boots.

* '''systemd-boot''': Simple UEFI-only bootloader, formerly known as gummiboot.

* '''[[Systemd/boot|systemd-boot]]''': Simple UEFI-only bootloader, formerly known as gummiboot.

* '''[[Limine]]''': Modern, advanced, multiprotocol bootloader and boot manager.

* '''EFISTUB''': Utilizes the UEFI firmware itself to boot the kernel, without the need for a traditional bootloader.

Most bootloaders like GRUB will show the NixOS version as the name of the generation (as shown with nixos-rebuild list-generations). To add a custom name for your build use [https://search.nixos.org/options?channel=unstable&from=0&size=50&sort=relevance&type=packages&query=system.nixos.label system.nixos.label]
