No, no need to take the CD out. Just hit the X at the top of the window, and you should get a message saying it might restart if you do that (hit Ok). And then once it restarts, hit a key again when getting the message "Press any key..." to enter the setup again. And then go to the page where you can start Startup Repair, and run it again. After the second time of running Startup Repair, hit the X again, except when it reboots, and you get the message "Press any key...", this time, do not press a key, so it tried to start Windows normally. If that fails, and you get a error message, you should be able to hit Ctrl + Alt + Del to restart the computer. And then that time, hit the key to enter the setup again, and run Startup Repair the 3rd time. And that should fix the problem.
