Recently I installed Windows 8, and after rebooting the system my DVD ROM device was not displayed.

So Here’s how I solved the problem :

1. Run Command Prompt as an Administrator. Type cmd in Windows 8 Metro UI and press cltr+shift+enter

2. Type following and say enter

reg.exe add “HKLM\System\CurrentControlSet\Services\atapi\Controller0″ /f /v EnumDevice1 /t REG_DWORD /d 0x00000001

3. Reboot the system

4. Verify if the problem has been resolved
