The Arch Linux project has released Archinstall 4.5, the latest version of its guided text-based installer, bringing expanded AArch64 support, new real-time Linux kernel options, additional translations, security improvements, and numerous fixes for installation workflows.
Archinstall 4.5 was released on September 29, 2026, roughly three months after Archinstall 4.4. The new version arrives just ahead of Arch Linux’s October installation media refresh and has already been packaged as archinstall 4.5-1 for Arch Linux repositories.
While Archinstall remains optional, it provides users with a guided way to configure an Arch Linux installation without manually performing every step described in the Arch installation guide. Version 4.5 concentrates primarily on hardware support, installer reliability, security, and expanding the range of systems that can use the guided installation process.
AArch64 Support Gets a Major Upgrade
One of the biggest changes in Archinstall 4.5 is improved support for AArch64, the 64-bit ARM architecture.
The installer can now handle GRUB and Limine EFI installations on AArch64 systems. It also gains support for the proper AArch64 root partition type GUID.
Previously, parts of Archinstall’s bootloader configuration were more heavily oriented toward x86_64 installations. The latest changes make its guided installation workflow more useful on ARM64 hardware.
AArch64 has become increasingly important throughout the Linux ecosystem. The architecture can now be found in cloud servers, development boards, laptops, workstations, and specialized computing platforms.
Supporting both GRUB and Limine EFI installations gives Archinstall more flexibility when preparing these systems.
GRUB Can Now Be Installed on AArch64
GRUB remains one of the most widely used Linux bootloaders, and Archinstall 4.5 extends its installation logic to AArch64 EFI systems.
This allows ARM64 installations to use a bootloader workflow much closer to what Archinstall already provides on conventional x86_64 UEFI computers.
The change doesn’t mean every ARM device will automatically become compatible with Arch Linux. ARM hardware can still have highly platform-specific firmware and boot requirements.
It does, however, remove an important Archinstall limitation for AArch64 machines that provide conventional UEFI environments.
Limine EFI Support Expands to ARM64
The same architectural expansion applies to Limine.
Limine is a modern multiprotocol bootloader supported as one of Archinstall’s bootloader choices. Archinstall 4.5 extends its EFI installation support to AArch64 as well.
