It sounds like you might have 2 issues:
If you don't see the default layout of the homepage with the text about DNN, the book and links modules, etc. then check and see if Portal 0 was created properly. If it was not, you probably have permission issues. The user that ASP.Net is running under must have certain permissions which are spelled out in the installation guide. Set your permsissions as instructed and reinstall. Also note that the ASP.Net suer must have reflection permissions. If this is not set properly, you'll see entries in the DNN log that mention reflect Permissions.
Secondly, if you don't see certain modules in the add module drop down, try this:
Try recopying the modules zip files to the \Install\Module folder and then running the following command:
www.mydomain.com/Install/Install.aspx?mode=InstallResourcesThis forced the modules to be installed for me. Why they didn't install properly the first time, I don't know.
