This will drop you into an initramfs shell:

    Start your computer. Wait until the Grub menu appears.
    Hit e to edit the boot commands.
    Append break=mount to your kernel line.
    Hit F10 to boot.
    Within a moment, you will find yourself in a initramfs shell.

If you want to make this behavior persistent, add GRUB_CMDLINE_LINUX_DEFAULT="break=mount" to /etc/default/grub and run grub-mkconfig -o /boot/grub/grub.cfg.
