Now BLFS documents how to install only the GRUB components missing in LFS, take the advantage. Also if efibootmgr is available, it's easier to just run grub-install w/o the --removable option instead of manually input some nasty efibootmgr commands.

|
|
On ARM64 systems, the following instruction builds GRUB for UEFI.
|
|
But because LFS lacks the FreeType package and the Unifont data
|
|
file, GRUB won't install any font for the boot loader and
|
|
the GRUB boot menu will be displayed using a coarse font or in a
|
|
smaller region on the screen.
|
|
If wanted, after the LFS system is finished, install
|
|
<ulink url="&blfs-book;general/freetype.html">FreeType</ulink>
|
|
and then install the GRUB compoents not installed from LFS following
|
|
<ulink url="&blfs-book;postlfs/grub-efi.html">the BLFS
|
|
instruction</ulink>, but remove the <option>--target=x86_64</option>
|
|
option and skip the command to install the
|
|
<filename class='directory'>/usr/lib/grub/x86_64-efi</filename>
|
|
directory.
|
|
</para>
|
|
<para>
|
|
If your system firmware does not support UEFI, you need to skip the
|
|
content of this page and try to figure out how to boot your system.
