dvd/rw-cd drive disappeared need help

[Xevier77]

Ok so i powered up my d820 dell laptop, and my optical drive is missing from My computer window. I checked my hardware manager and have a yellow exclamation point on that drive. So i disconnect it and put it back in comes back as same. I disable it/enable it same. I uninstall/and let it reinstall it does the same again.  Says something like the registry for this driver is damaged. Please help I know small things to do to fix computer problems, but I haven't faced this yet.

4. Go to Device Manager, click a "+" sign next to IDE ATA/ATAPI Controllers.
You'll see two items:
- ATA Channel0 (or Primary Channel)
- ATA Channel1 (or Secondary Channel)
Right click on each of them, and click Uninstall. Confirm.
Restart Windows. They'll be automatically reinstalled.

Also, insert a bootable disc in the drive and reboot. Does the system see the disc / drive at boot?
