<para>If the recommended dependency <xref linkend="freetype2"/> is not

if <command>grub-mkfont</command> is not built, or the unicode font

data is not avaliable at the time GRUB is built, GRUB won't install

any font for the boot loader. The GRUB boot menu will be displayed

using a coarse font and the early stage of kernel initialization will be
|

in <quote>blind mode</quote> — you can't see any kernel messages before

the graphics card driver is initialized. It will be very difficult to
