You mean the PowerPack?
The other cds have non-free software that you've paid for in the price of the pack, and those arent needed til after you get the install booting properly.
Do you mean you get a list of items all load [OK], but then no graphical login?
Try pressing Ctrl+Alt+F1 at this point, then log in as the user you added at install(not root this time) and then try the command startx
If you can log in but that command causes an error, state it here, and try again but this time log in as root. Use exit
to get the login prompt again.
What graphics card do you have?
