OK, got new DVD from apple, different ram, and different DVD Drive, and had same problem. RE-set pram and nv-ram, same problem, disconnected additional drive, same problem, unhooked everything back up, reset pram, nv-ram, permissions, ect, chose easy install, and it installed everything fine? I have notice one of the 256 ram's do not show up, I might change this out.. Thanks for all the help, I am now up and running great. Thanks
