Did that include the boot partition, where the kernels and initramfs'
are?

Did you remove rhgb and quiet from the kernel boot parameters?  That
should show you the stream of messages from systemd as the system
boots, and the error should be near the end of that stream, so it
should still be on screen when the crash happens.  I think you hit
space or escape during boot to get the boot menu, and then you can edit
the line.  I have a timeout, so I always see it.

Does it drop to a dracut or grub prompt?  If it does, it is also
possible to view the temporary boot logs from there (I think they are
under /tmp (/var/tmp?)). It's painful because the shell is very limited.
Use
ls /bin
to see the available commands.  I think less is there, as is vi.
