I have the same issue. DVD drive is gone after updating to Windows 10.
I tried to remove it from the device manager and reinstall it Didn;t help.
Also changing some regedit options didn't work either.
I read something about updating the chipset, but there are no drivers available for the Lenovo Z50 75.
Anyone has a solution?

And I'm pretty sure that there is more users with same issue. I was thinking about of reinstalling Windows 8.1 where DVD whas working fine, extract driver, and reinstall Windows 10 from 0. Maybe I'm lucky and I can install the driver. What do you thiink?

As per Win 8.1 on my 64bit Z70
Its a Microsoft Component supporting it. If its detected properly the repective driver should be applied. Its not model specific to an individual DVD make/model.
You really need to call Lenovo on this for a resolution. This is a user forum primarily. You're unlikely to hear from anyone with a fix.This as well as HD's sit on the SATA bus via the controller. In my case its an Intel 9 series chipset controller. The DVD support is loaded accordingly.
See Below for reference.

This is really irritating. I did a clean install of Windows 10, not only has the DVD drive become useless but the sound(card?) has issues too.
To top it off, my back up HD has failed and I cant even install 8.1 anymore.
This has left me with repeated instances of re installing Windows 10 from the recovery partition only to find the same old score......unrecognised driver/DVD/CD rom.
I first tried the registry tweak 'Hkey' etc, but that wouldnt work. I alo searched the internet for days and eventually found the AMD chipset driver zip, installed it, but it still didn't recognise the discs or eject them. I also tried this with the combination of Hkey, but it is still pretty useless.
Back to a clean install, once again! Waiting for an answer to this charade.
This machine is under warranty but it seems that owing to third party software (yes, Microsoft) the issue cannot be resolved by my retailer either. Tossers!
So, basically I am left with a machine that cannot any longer provide me with the functions for which it was originally intended. Surely there is some laws about this sort of thing?
Come on Lenovo, we customers pay your wages in a roundabout way, how's about giving us some answers and resolutions to these issues?
Completely fed up.

Call Lenovo Tech support !!!
You may likely have to send the unit in if in fact the HD or something else has also failed. They can reimage the oringinal Win 8.1 back

My apologies. I should have said that my "External Hard Drive" has failed and not my main PC drive. This held my functioning, updated version of the backup of Windows 10 prior to the clean install.
Leading you up the wrong path. Sorry.
The real problem lies with the DVD/CD not detecting any media after AMD chipset firmware was installed.
I am currently doing a clean install again, just to see if it may resolve any issues.

Well if its due to Win10 a corrupted key or wrong info.
If you see it in the bios and or you can boot from media then thats likely something in the registry keys.
You should call Tech support as they should be able to point you to where to go and fix it. Cut to the chase.
