I have a dual 2.0 ghz G5 i'm prepping to sell. I'm trying to do a clean install of the OS, but it just sits there and hangs up on the Select a Destination part. It shows the harddrive greyed out, but it won't stop spinning/processing, to continue. the original HD crashed, and I installed this new drive and ran on it with no problem. the old broken drive is still connected, but is dead, could this be the problem?
