Just like before you may have to install drivers for the motherboard and other things. There are no drivers for the DVD drive. Microsoft supplies the OS with a basic set of drivers so back to the desktop maker to talk about the other drivers.
My desk top computer has two HP1260i DVD drives. After upgrading from Windows 7 professional to Windows 10, only one of the DVD drives works. Device manager only lists one DVD drive (working OK). I have disconnected and reconnected the drive, also I have checked the drivers, but the second optical drive will not show or work.
When I swap my hard drive with one running Windows 7, both drives work just fine again.
If both drives were not working, I would understand it (plenty of people seem to have this problem), but for one to work and the other not puzzles me.
I would be grateful for any advice.
