Guys, I think I really messed up. A while ago I installed windows 10 onto my 27 inch, 1tb iMac (2017) and everything was working as expected. Then I decided to update to the beta version of macOS Mojave and everything was working as expected. But today when I wanted to boot into windows 10, instead it would just boot me into macOS. I tried to boot a couple of times but it never booted in windows 10. So I decided I've had enough, opened bootcamp assistant and clicked on the button Restore disk to a single macOS partition. Then an error message popped up, saying that it couldn't complete the task (or something like that, can't quite remember). I restarted my Mac holding down option and saw that the windows 10 disk image had disappeared. I thought everything was fine, until I opened disk utility and saw that Macintosh HD only had a total capacity of 876.7 GB. This is weird, where did my 200 something GB go? Disk Utilities sidebar does not show any sign of a windows partition and the fusion drive tab shows it having a total capacity of 1tb but Macintosh only having a capacity of 876.7 GB. Is this just a visual glitch or is my Fusion Drive messed up? Please help!
