I would recommend using the "D" drive letter only for a DVD/CD player.
My rule of the thumb is don't use A, B, or D. Let Windows 7 decide what to do with them.
dvd drive not shown in Disk Management, but works

The DVD drive works before Windows starts, but not after Windows is running, right ?
It might be a DVD drive firmware problem, BIOS version problem, MB chipset driver problem, Registry problem, etc.
You can google for dvd drive not recognized windows 7 and find others have this problem.
Here is one thread you can look through:

I would run a System File Check to make sure there are no errors:
SFC /SCANNOW Command - System File Checker

If the info might be helpful, here's my best guess (and reasons why):
You boot into BIOS
BIOS detects the hardware and you can boot from the drive while in BIOS. As you said, that tells us the drive is there and working
Machine next boots into Windows
The first step in PnP protocol is device detection
- Devices detected and recognized appear in Device Manager. IMO the best place to start when you have missing devices is Device Manager. If the device isn't in Device Manager, it will never appear anywhere else like the "higher" functional levels (like Disk Management, File Explorer or My Computer)
- Your DVD isn't in device manager (nor are any "Other devices" listed - where a device might also appear if device detected but no driver found) which IMO points to a Windows PnP device detection problem. (Drive letter issues apply to Disk Management so wouldn't be relevant in this case since you never make it to Device Management)
Device detection is handled between the bus controller and the device (your DVD drive in this case) and the PnP bus that connect them.
> Make sure you have the latest chipset drivers installed
> Even if installed, reinstall them
> Check for updated BIOS for you m/b
/* EDIT */
p.s. The shut down, disconnect all power a few hours, reconnect (as some one else already mentioned) is also worth a try. It can reset a controller
/* EDIT2 */
And as also referred to by someone earlier in a thread they provided: a firmware update on the drive may help too (if one exists). But easier said then done when it doesn't connect. Which is why i'd try other things firstLast edited by ComputerGeek; 15 Dec 2015 at 18:52.
