Installed new HD on my iMac and after  that I  did the restore of Time Machine with my external HD. On the reboot I keep getting a message saying "You need to restart your computer. Hold down the Power button until it turns off, then press again." The screen turns green with a bunch of words and numbers. Some of the words say, Mac OS version: Not yet set. Don't understand most of it. Don't know what to do. Everything was going along fine until this. Help,, Thanks Peter
