On my laptop (ACER Aspire E5-521G) the CDROM/DVD is not visible (device manager – explorer) in windows 10 after upgrade albeit I can see and hear that it is trying to do something when I put a cd on the tray. I’ve tested ALL tips both on Microsoft support page and other tricks found on the web. NOTHING works!

The funny thing is that in BIOS if in UEFI mode (which it must be to be able to boot) the ATAPI devices aren't showing up – no info is listed at the CDROM, see image 1. No CDROM - UEFI mode

But if set the boot mode to LEGACY the CDROM shows up – name and all, see image 2. CDROM, name and all, LEGACY mode

Any last suggestions to make my cd/dvd work again?

  • Try resetting upper and lower filters. This has worked for me before: 1. Close down all open programs 2. Open regedit.exe with Run as Administrator 3. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\....…{4D36E965-E325-11CE-BFC1-08002BE10318} 4. There should be one of, or both of, UpperFilters and LowerFilters 5. Click on UpperFilters, Edit Delete 6. Click on LowerFilters, Edit Delete 7. Close down regedit trees and close regedit 8. Open Device Manager and Uninstall DVD / CD Drive 9. Shut Down 10. Restart and DVD / CD Drive should come back with auto discover – John Sep 30 at 10:50
  • THANK You for your suggestion but that is one of several solutions I've tried, or rather cheked out but there has never shown either upper or lowerfilters under that post, so no success ... – Anders Dahlgren Sep 30 at 11:56
  • DVD drives can be troublesome. You can try updating the drivers in Device Manager. Open Device Manager, go to the DVD drive, right click and update drivers. There are more ideas in this article below: groovypost.com/howto/… – John Sep 30 at 12:06
  • THANK YOU for your support but the problem is that the cd/dvd is not present in the device manager (even when show hidden devices is switched on). As of that it is impossible to uninstall the cd/dvd since it isn’t there. The only way to see the cd/dvd is when I go into BIOS (shown in my attached images in the first post) and change the BIOS start mode to Legacy. But then again, I can’t boot the laptop in Legacy mode since Windows 10 wants it to start in UEFI mode. There must be something happening in this mode (UEFI) that hides and makes the cd/dvd unusable. – Anders Dahlgren Sep 30 at 12:45
  • There must be some issue with the DVD drive if it does not even show up in Device Manager (Basic device availability in Devices) is independent of Windows). Can you try a USB DVD Drive and see if that is picked up? – John Sep 30 at 12:55
