Can't see DVD drive in Windows 8 Developer Preview
I have installed Windows 8 Developer preview, but it won't show my DVD Drive in my computer.
What is the problem?
(I don't know which information about my computer is useful, if you need information, please let me know in comments)
Edit : DVD Drive isn't exists in Device manager. Also I have a windows 7 on same machine, and windows 7 shows DVD drive correctly.
