I need one week to find out why CD\DVD drive isn't recognized in newly installed Windows 8. There was two strange things:
1. CD/DVD is listed in BIOS.
2. Windows 8 was installed from DVD
But in Windows 8 CD/DVD drive wasn't recognized. After many hours searching on the web, I found a simple solution on Microsoft forum.
1. Open Command-Prompt window as an Administrator.
2. Run the command:
reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001
I'm sure Microsoft will add this line in next update... but until then, you can use this solution.
