Windows working with Option key, not visible in Bootcamp

[lapino]

Hi guys, small problem here. I cannot "see" my Windows partition from the preferences pane in bootcamp (osx) (where I would go to set Windows as a boot partition). The only way I can make Windows to start is by using the Option key at boot.

Strange this is, the partition is visible on my Osx desktop (mounted), I can browse the files etc... but Bootcamp somehow thinks it's gone. Any idea?

Can you see it in System Preferences > Startup Disk?

You can also boot from there into Windows.

No I can't, that's exactly what I wanted to tell you guys. This is my problem, it doesn't show up there

I posted a few likely explanations on this other thread on MacRumors, no feedback yet on whether they worked out or not: https://forums.macrumors.com/threads/695612/
