failed windows 8.1 installation through bootcamp

Hi,

I was trying to install a windows 8.1 partition on my macbook pro through bootcamp assistant. All of a sudden my computer restarted and the message "Your computer restarted because of a problem." appeared on my screen. When I logged back in I found that there was 40GB missing from my storage and I couldn't find my windows 8.1 partition anywhere. It still shows that my Flash Storage has a capacity 121GB but my Macintosh HD only shows a capacity of 80GB... Can anyone help me with this and help me restore my mac to the way it was? Thank you.

*I am not very tech-savvy so I'm sorry in advance if my explanation seems kind of simplistic.

MacBook Pro (Retina, 13-inch,Early 2015), OS X El Capitan (10.11.1)

See Bootcamp Assistant and 'lost' disk space . Your case is issue #2. You may be able to fix it using the associated link.

Post the output of

diskutil list

diskutil cs list

before you erase the SSD. Unless there is a hardware issue, your SSD should be erasable.

I've had the same problem two days ago, if I'll do the backup now in this situation (the HD occupy 80GB and the free space partition is about 40GB) and after that I'll erase the whole disk, should I be able to have back all the free space (120GB)?

Before erase the disk I made some researches on the community and I found this issue: My Macbook Pro Retina doesn't see internal SSD drive

Could it happen to me also ? I'm sorry if the question seems stupid, but i've never erased an SSD so I want to be sure that nothing bad will happen when I'll restore from Time Machine. That something I can do to avoid this situation?

Yes, you can re-install OS X using About macOS Recovery - Apple Support .

Yes, and when you restore the backup, you will get contiguous free space, which should allow BCA partitioning.
