I have installed everything and Sharepoint 2010 seems to work fine even though it did fail configuration due to not being able to load sample data.
When I go to configure project server Central Administration > Manage Service Applications > Project Server Service Application I get :
Could not load file or assembly 'Microsoft.Office.Project.Server.Administration.ApplicationPages, Version=126.96.36.199, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified.
I saw the exact samething happen when I failed to reboot the server after installing SharePoint 2010 binaries. I wiped the install [saved after installing OS and SQL] and started again and this time rebooted after SP 2010 binaries were installed and then loaded PS 2010 and it got past the Sample Data and loaded fine.
