In order to boot Arch Linux, you must install a Linux-capable boot loader to the Master Boot Record or the GUID Partition Table. The boot loader is the first piece of software started by the BIOS or UEFI. It is responsible for loading the kernel with the wanted kernel parameters, and initial RAM disk before initiating the boot process. See below for boot loaders available.

Note: Loading Microcode updates requires adjustments in boot loader configuration. [1]

Feature comparison

Note:
  • Boot loaders only need to support the file system on which kernel and initramfs reside (the file system on which /boot is located).
  • As GPT is part of the UEFI specification, all UEFI boot loaders support GPT disks. GPT on BIOS systems is possible, using either "hybrid booting" with Hybrid MBR, or the new GPT-only protocol. This protocol may however cause issues with certain BIOS implementations; see rodsbooks for details.
  • Encryption mentioned in file system support is filesystem-level encryption, it has no bearing on block-level encryption.
Name Firmware Multi-boot File systems Notes
BIOS UEFI Btrfs ext4 ReiserFS v3 VFAT XFS
EFISTUB Yes ESP only Kernel turned into EFI executable to be loaded directly from UEFI firmware or another bootloader.
Clover emulates UEFI Yes Yes No without encryption No Yes No Fork of rEFIt modified to run macOS on non-Apple hardware.
GRUB Yes Yes Yes without zstd compression Yes Yes Yes Yes On BIOS/GPT configuration requires a BIOS boot partition.
Supports RAID, LUKS1 and LVM (but not thin provisioned volumes).
rEFInd No Yes Yes without: encryption, zstd compression without encryption without tail-packing feature Yes No Supports auto-detecting kernels and parameters without explicit configuration.
Syslinux Yes Partial Partial without: multi-device volumes, compression, encryption without encryption No Yes v4 on MBR only No support for certain file system features [2]
systemd-boot No Yes Yes No No No ESP only No Cannot launch binaries from partitions other than ESP.
GRUB Legacy without GPT No Yes No No Yes Yes v4 only Discontinued in favor of GRUB.
LILO without GPT No Yes No without encryption Yes Yes MBR only [3] Discontinued due to limitations (e.g. with Btrfs, GPT, RAID).
