Replaced HDD with new HDD. Old system was windows 7 on Toshiba Satellite l675 with 4gb ram. Downloaded Linux Mint Cinamon on blank DVD, verified it. Ran DVD and was able to use Linux while DVD was in. Then clicked on install Linux Mint on screen and went thru installation process again. Finished and got message to remove install media, which I did. Then pressed enter as directed and nothing happens. The screen still says "Please remove installation media and press enter". Please help. Thanks John
