I installed Ubuntu on a spare 20GB hard drive I had lying around... My only problem is that I can't log in

When it was installing, I set the default username as Josh, and set my password, but it won't log in. I don't know how to get into root either... How do I reset the password for "Josh", and how do I access "root"? Will I be able to access them from the GUI login screen?

Make sure it wasn't josh and not Josh. If you can't log in, try booting with the argument init=/bin/bash in Grub. That should let you reset the root password (use "sudo passwd root") and your password ("sudo passwd Josh").

on ubuntu root is disabled by default

so no you cant log in as root.
