Install

pacman -S limine

Deploying Limine on UEFI systems involves copying the file /usr/share/limine/BOOTX64.EFI to the EFI system partition, and to make the UEFI BIOS aware of it:

mkdir -p /boot/EFI/limine
cp /usr/share/limine/BOOTX64.EFI /boot/EFI/limine/

Limine does not add an entry for the boot loader in the NVRAM automatically. Use efibootmgr to setup an entry for Limine:

• https://wiki.archlinux.org/title/Efibootmgr

Install

pacman -S efibootmgr

Create an entry (replace /dev/sda accordingly):

efibootmgr --create --disk /dev/sda --part 1 --label "Arch Linux Limine Bootloader" --loader '\EFI\limine\BOOTX64.EFI' --unicode

Execute

nano /boot/EFI/limine/limine.conf

Add (replace /dev/sda2 accordingly)
