I have a Mac with two 2TB SSD. The first SSD is for macOS Hight Sierra and virtual Windows 10 system with Parallels 13. The Windows 10 OS works perfekt. Now I am trying to add the second ssd as Boot Camp HDD to the virtual system. The problem is, that the second SSD is not seen as Boot Camp HDD in parallels settings. I have the same configuration on another Mac with two 500GB SSD and Parallels 11. This configuration works and I can see the second SSD as Boot Camp HDD. What is the issue? Why I cannot add the second SSD as Boot Camp HDD?
