Error messages flash up briefly during boot and shutdown - are these logged anywhere?

I get errors at the beginning of Ubuntu startup. But it disappear fast, because of this I am not able to see the errors. Also while shutting down i see some of the errors. Want to know what it is. Is there any logs to track these errors? that will be helpful to check what it is.

Some of the messages from boot go into dmesg, which can be read using the dmesg command or at /var/log/dmesg - particularly if they are kernel messages.

Some messages will go into /var/log/syslog, particularly if they are from services or startup scripts.
