No, unplug the device (CD/DVD drive) only.

By the way, as you're obviously a beginner in PC hardware stuff, I would recommend that you ask a knowledgeable friend (neighbor, school mate etc.) to explain basic things to you. Perhaps, you could try to find a Greek forum if you're having problems with the English language. You may get better results by doing that; by asking such simple questions and waiting for the answer for hours, you will not solve your problem within a year...
