You can try "single user mode" or "recovery mode" o something like that
in the menu of your boot loader (grub, I supppose, if your machine is
i386 or amd64). If even that fails, try adding init=/bin/bash at the end
of the kernel commandline in the boot loader.
Then the logs are in /var/log/ (if /var is mounted; if not: mount /var)
If you are not familiar with the boot loader, and the way of editing the
kernel commandline in the boot loader, see
