In some cases your DVD drive may be missing on Windows 7, even if it's visible in the BIOS and using the standard driver.
The standard solution here is to
- Go to run REGEDIT,
- Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\,
- Then delete both UpperFilters and LowerFilters in the right-hand pane (UpperFilters.bak and LowerFilters.bak entries can be ignored).
No change? Resetting the drive letter has worked for some. Click Start
, type Disk Management
and choose the "Create and format hard disk partitions
If your optical drive is visible here then right-click it, select Change Drive Letter and Paths, click Change and choose a new letter.
If the drive is now visible in Explorer, then repeat the process to change the drive letter back; if it's still not visible, reboot and it should appear.
