Just an update regarding my issue.
I saw in a post via reddit that someone mentioned having problems with the oculus after updating the windows 10 to the creators update.
So, I’ve decided to install a dual-boot system with the windows 10 anniversary updated alongside and to my surprise it worked.
Now the rift is working with windows 10 anniversary update but not with the creators update.
Mind you though that I haven’t changed anything (bios-wise) and the drivers installed are exactly the same, and both OS'es were updated to their latest build.
Perhaps there is something in the creators update that is causing issues with the oculus.
In any case, my issue is sort of solved – I don’t mind dual-booting.
