Hi Emmanuel,

You can follow the below methods to solve this problem of missing DVD drive in your PC:

Method 1
I suggest you to run Hardware and Devices troubleshooter:
To open the Hardware and Devices troubleshooter, follow these steps:

1. Press the Windows logo key + R to open the Run dialog box.
2. Type control in the Run dialog box, then press Enter.
3. In the Search box in Control Panel, type troubleshooter, and then click Troubleshooting.
4. Under the Hardware and Sound item, click Configure a device. If you are prompted to enter an administrator password or provide confirmation, type the password or provide confirmation.

Method 2
Update or reinstall the driver:
To update the driver, search for the driver on the device manufacturer's website, and then follow the installation instructions on the website.

To reinstall the driver, follow these steps:

1. Press the Windows logo key + R to open the Run dialog box.
2. Type devmgmt.msc in the Run dialog box, then press Enter. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow
3. In Device Manager, expand DVD/CD-ROM drives, right-click the CD and DVD devices, and then click Uninstall.
4. When you are prompted to confirm that you want to remove the device, click OK.
5. Restart the computer.

After the computer restarts, the drivers will be automatically installed.

Method 3:

Click start button and type - Device Manager - and hit enter (Device manager will open up)
Now in the Device manager window you'll see a list of devices such as Computer, Disk Drives, Display adapters. ect ect.
Look down the list and locate 'IDE ATA/ATAPI controllers' click on the little '>' symbol to the left to expand it and you will now see a list of controllers that will look something like this:

• ATA Channel 0
• ATA Channel 0
• ATA Channel 0
• ATA Channel 1 
• ATA Channel 1 
• ATA Channel 1

There may be a few longer named ones underneath but ignore those ones.
Now right click on the ones listed above and select 'uninstall' one at a time, and as you uninstall the last one your computer will prompt you to restart, after the restart your drive should now be visible.

I hope this helps.

Regards,
Lokesh
