first of all I must say I'm pretty amazed by all the help and great contributors on this site. I already tried a few different Solutions but I came to a point where I couldnt help myself furthermore.
Windows Installation failed
I tried to install Windows 8.1 on my 27" Retina iMac Late 2016 with 1TB of Fusion drive. Everything went fine, after the Bootcamp Setup the Windows Setup started.
During the Windows Setup i was asked to choose a Drive to install on. Since I created a 200GB partition with Bootcamp I wanted to use this, Windows denied to install it. I'm very sorry I can't remember what windows told me.
I formated the partition with windows hoping it would work afterwards. It didn't. Then I deletet the partition hoping creating a new one with windows would solve it. It didn't.
I canceled the windows installation and booted Macintosh. Bootcamp told me it couldn't start an installation because it's not formatted.
Bootcamp Partition deleted
I decided to delete the Bootcamp partition, soon after I realized how stupid this would be. Anywys Bootcamp itself never offered me to remove Windows. So I kind of had no choice.
I could not delete the 150MB "disk1s5" for whatever reasons but after a while i created an empty journaled "WINDUMB" partition which I couldnt resize. My Mac told me it cannot be resized. Also the [-] wasn't clickable.
I deleted WINDUMB to ExFat, FAT and APFS. APFS let me click [-] but deletion failed.
Recovery Diskutil
In recovery, following this Problem and another Solution (found on another forum) that would just delete CoreStorage wouldn't work.
I could not resize my cs. My mac tells me that I cannot resize a volume that exists on 2 physical drives or something like that.
David Anderson 'Partition Recovery' Approach
Worked fine but my diskutil didn't load after deletion so I had to restart. After restart my Diskutil just shrinked my Fusion Drive to 809,9GB instead of showing "empty space". I coulnd't work it out with First Aid.
Solution Request
- I'd like to recover the lost ~200GB of Storage from the deletion
- The recovered disk space should be merged with Macintosh HD
- Windows may still be an issue if possible. Hints for successful installation are welcome, otherwise I might research for issues using a fusion drive with windows
