I was switched from Windows 7 to Windows 10 some time ago. Recently, I found that my US-made DVD's play OK, but one I received from England, which played just fine on Windows 7, won't start up on Windows 10. Why not?
What is the region setting for the dvd drive? Also make/model of computer - and if possible the dvd drive too?
Most likely a drive issue rather than Windows 10. You are only allowed a few goes at changing regions, so maybe time ran out See here:

You could also try updating or rolling back the driver for the DVD drive. You have to be a little bit crazy to keep you from going insane.
