What can I do if I can't find the DVD drive under Windows 7

        Some users responded that Windows 7 still reported that the DVD could not be booted when Windows 7 was installed, but the DVD driver can be seen in the motherboard settings. For this problem, I also searched the Internet for the solution. Here is a reference for everyone.

run "regedit" find HKEY_LOCAL_MacHINESYSTEMCurrentControlSetControlClass, and then delete the file right on the lower level filtering information can be.

or Start menu, enter the disk management command to select Create and format hard disk partitions. Find the problematic CD-ROM drive in all hard disk partitions, right-click, choose to change the disk name and path, and restart the system to complete the operation.
