Hey!
Yesterday I installed macOS Sierra on my Mac-Partition. Everything went fine until i wanted to change to my Windows Partition. Instead of the Windows Partition i found this:
If I select the right option the Mac booting screen appears. Somehow my Mac can't find the partition although it still exists with all the files (tested it with a recovery program). I installed a backup of my system but the partition is still gone.
Is there any way for me to recover the windows partition?
Thank you!
