Dvd drive not identified yet. - Windows 8

I am a user of windows 8 developer preview and it doesn't show any dvd drive installed on my computer.

Please start at the top and do all of these even though you have done some before as it is often the
total process which solves the issue.

Try this - Control Panel - Device Manager - CD/DVD - double click the device - Driver's Tab - click
Update Drivers (this will likely do nothing) - then RIGHT CLICK the drive - UNINSTALL - REBOOT
this will refresh the default driver stack.

good luck.
