CD/DVD player does not show up in device manager Win10

[SamBalby]

Hello, I upgraded an old 6910P  laptop from Vista to Windows 10, 32bit , doing a clean install. Everything is working, exept the CD/DVD drive: it is not listed in Device Manager (not even with an exclamation point). I found some solutions to delete the upper/lower filter registry keys and add a Controller0 key and subvalues, but still not found.

The hardware is OK, since I can boot from a bootable DVD no problem. It's definitely  Windows10 related ,   What else can I do to have the CD/DVD drive show up in device manager?

When you're booting from the drive, it is not using Windows drivers because those have not been loaded yet.  So clearly, the BIOS sees the drive and can read it.

But you're not going to find Win10 CD/DVD device drivers for Vista-era hardware.  That's the issue.

Hello WAWood, thank you for you suggestion, but it turned out to be quite simple: the CD/DVD drive is called "notebook multibay"  in the BIOS. Once that is enabled, the cd/dvd  player is detected and works just fine in Win10. 

Leaves me with the questions (A) why that is suddenly a problem in Win10 (not Vista) and (B) why a bootable DVD apparently ignores that setting, but anyway, I'm up and running!
