Are you sure you put the disk in the CD rom? I've never heard of this. Perhaps you accidentally inserted it below or above the drive. Try taking a look in those openings to see if you can find it.
Hello. I opened up the case and placed the disc in the drive. When I opened it back up the disc wasnt there. I looked under the laptop, on the floor, in the case etc. There is only one slot. I never left the table where I was working so I didnt misplace it. Yes, this feels very twilight zone. The only conclusion is that it slid out inside the laptop. Is this possible?
