Ubuntu stuck at "Please Remove installation media and close tray and press enter"

Solution 1:

Four possibilities:

• There's a problem on your PC and its partitions. Perhaps you can wipe the area you want to install Ubuntu on and then try again.

• There's a problem with your installation medium. Unlikely, though, because such an issue would have shown up earlier, I would think. You could try making a new one.

• Your computer is unable to know when the tray is closed. Then you have a hardware problem that will probably require replacement. But it sounds unlikely.

• There's not really a problem, and Linux was installed successfully. Just that the Enter thing doesn't work. If you reboot the computer at that moment, can you use Linux? Because this message usually means the installation was successful.

Solution 2:

I experienced the same thing. What I did was, pressing the restart button (for 20 seconds)until everything went off, then when my PC restarted, there you go! The fresh uBuntu. I am uBuntu newbie. :)
