BIOS Boot is not officially supported anymore
eweOS only support UEFI bootloaders. There may be some packages supporting BIOS booting but they're not officially supported.
We use limine as replacement for grub. It is the default bootloader for eweOS.
pacman -S limine
Install limine and create corresponding boot entry.
limine-install --efi-directory=EFI_PARTITION_MOUNTPOINT TARGET_DEVICE
For firmware that doesn't support setting EFI variable at runtime (e.g. U-Boot), or only looks for removable boot paths (in particular some MSI boards, this is a firmware bug!), it may be necessary to install the bootloader in removable mode.
limine-install --removable --efi-directory=EFI_PARTITION_MOUNTPOINT
Note that for each storage device, there's only one bootloader that may be installed as removable. Please make sure this doesn't override your other bootloader configuration before running this command.
Generate limine configuration
limine-mkconfig -o EFI_PARTITION_MOUNTPOINT/limine.conf
Currently kernel updating and initramfs generation is handled by limine-mkconfig as well, so running limine-mkconfig (without arguments) may be needed after a system upgrade or changing initramfs configuration. It copies kernel and initrd to EFI_PARTITION_MOUNTPOINT/, thus it's recommended to use the EFI partition as the /boot directory for simplicity.
limine-mkconfig would only read kernels located at /usr/lib/modules/ AND belongs to packages installed by pacman. Single user mode menu options will also be generated.
