Raven<p>When there are UEFI entries missing for your Linux operating system, you can add them easily with efibootmgr:</p><p>As root: efibootmgr -c -d &lt;disk&gt; -p &lt;efi-partition&gt; -L &lt;entry-name&gt; -l &lt;loader-path&gt;</p><p>For example: efibootmgr -c -d /dev/nvme0n1 -p 1 -L "debian" -l "\EFI\debian\grubx64.efi"</p><p>It will use /dev/nvme0n1p1 and on it the file /boot/EFI/debian/grubx64.efi and add it to the UEFI boot menu. On next restart, the entry should be there.</p><p>NOTE: You have to replace "/" with "\" for the loader path.</p><p><a href="https://mastodon.bsd.cafe/tags/efiboot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>efiboot</span></a> <a href="https://mastodon.bsd.cafe/tags/grub" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>grub</span></a> <a href="https://mastodon.bsd.cafe/tags/linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>linux</span></a></p>
