I plonked a cd in my laptop and nothing happened.
I looked in my computer and there was no E drive which is the cd/dvd.
I looked in device manager and it is not there.

I re-started the laptop with the disk still in and hey oh, the cd played, and E was showing in my computer.

I took the disk out, restarted the laptop, popped the cd in to play and once again nothing.

I presume if I put the disk in and restart with the disk in then it will find it again, but I don't know why this is happening or what will happen when I shut down completely.

I did do a registry clean but I didn't like the programme so deleted it so that is probably where it has gone wrong, the question is how do I get it back?
