I did a factory reset of my laptop (XPS L502X) to go back to Windows 7 from Windows 10 (due to certain incompatibilities).
Afterwards , drive won't read software .
It will however happily burn to a blank disk (using Roxio). It won't however then read the contents.
It will play pre-recorded Film DVD's
I have tried suggestions on these forums such as deleting the driver then re-flashing the BIOS (BIOS is latest version).
I have tried the Microsoft Fixit
Drive is an optiarc dvd+-rw ad-7717h
Device Manager describes it as a CD-ROM
Any ideas please? Need a Christmas Miracle!
