<h2>Manually booting from GRUB</h2>
<p><i>2026-02-23</i></p>
<hr />
<p>
Sometimes, (at the fault of my own) GRUB falls over and fails to boot my system. Assuming this
is not a catastrophic issue and more so something like mistakenly forgetting a
<code>grub-mkconfig</code> after installing a different kernel, or the kernel complaining it
does not have the correct root partition passed to its boot parameters, not all hope is lost.
Reboot and enter GRUB's command line (pressing C) and poke through the available file systems
to find where the kernel and initramfs live:
</p>
<pre><code>grub> ls
(hd0) (hd0,gpt0) (hd0,gpt1) (hd0,gpt2)
grub> ls (hd0,gpt1)/
vmlinuz-6.10 vmlinuz-6.10.old initramfs-6.10 initramfs-6.10.old
grub> root=(hd0,gpt1)
grub> linux /boot/vmlinuz-6.10 root=/dev/sda3
grub> initrd /boot/initramfs-6.10
grub> boot
</code></pre>
<p>
Here, <code>/dev/sda3</code> is the partition value passed to the kernel to boot. This is
where <code>/</code> lives. However, one may consider omitting GRUB entirely and booting
directly from an EFI Stub.
