I totally screwed up my SSD in my iMac 27" (late 2015) with my first try, to install Bootcamp (only have a Mac since end of 2017). I checked Youtube videos and other websites for instructions how to do that. Looked simple enough. But when I started it, i got to a step that I didnt see in any other tutorial. Bootcamp prepared my drive, i split around 130 GB from my 500 GB SSD, and after that the Mac rebooted and the Windows install started. Entered my key, and then I got to the part where you (when you install Windows on a PC) choose the Harddisk / Partition you want to install Windows on. I knew that part from Windows, but non of the other tutorials showed that step. There was the Bootcamp partition, but I couldnt use it, even after reformating it. I guess things went out of hand after that point. I started to panic, didnt know what to do anymore. Back in MacOS, i tried to run bootcamp again, to maybe delete what happened. But that didnt work anymore. Tried recovery, was able to remove the partition with GPT commands. When you go to Diskutil, it only shows the remaining MacOS space on the SSD. So basically all but the space that was technically assigned to install Windows on. My MacOS still works, but I dont know how to get my previously assigned (and now it seems to be gone somewhere) disk space for bootcamp back to MacOS ? Unnecessary to mention that my first attempt with Bootcamp really was not the experience i hoped for or expected, and will probably never try that again. I really need some help guys. I still have my Time Machine backups, so I can still restore and install it again with all my stuff. But as it is, when I try, the drive still gives me the 369 GB space thats left, without the restored space from the failed bootcamp. Please help me, I dont know what to do anymore.
