[SOLVED] I messed up adding a kernel line, am I screwed?

So I don't have a CD or USB stick to use at the moment.
I boot into rootfs (which I have never experience before and it seems I am limited here) because:

   

 ERROR: Root device mounted successfully, but /usr/lib/systemd/systemd-bootchart does not exist.

I was trying to improve boot speed and added the kernel line:

   

initcall_debug printk.time=y init=/usr/lib/systemd/systemd-bootchart

In the file /etc/default/grub/grub.cfg file and then did the relevant grub-mkconfig, and now I'm stuck.

Is there anything I can do? I had a normal working arch install but now I have nothing.

You should be able to edit the menu entry before grub boots it.

Thanks, I had forgotten that I have the grub menu hidden and needed to hold shift to display it again.

Using your link I was able to just press "e" on the Arch linux entry, remove the offending lines, and press Ctrl-x in the editor to launch with those kernel lines removed.

It boots!
