Boot Camp Fail. Genius Bar struggling
I have been trying to install BootCamp onto my 2013 iMac. However, I cannot get past failed partition "Your disk could not be partitioned. An error occurred while partitioning the disc." The closest I have come was after the Fusion Drive was replaced, I tried to make a 200GB partition and it got 3/4 the way through. That is the ONLY time partitioning has even remotely worked.
Among thing I have tried
- Terminal DiskUtil shows all the correct disks and no phantoms.
- Zapped PRAM
- Disk Utility from Recovery Mode
- /sbin/fsck -fy
- One time, I found the partition mount points and I saw what appeared to be a Windows partition, I did something and it was gone. I literally cannot remember what commands I used to get that view, how I started up or anything.
Genius Bar
- I have visited the Genius Bar 3 times. Every time, the techs put it through the triage and all systems check out fine. The 1st time ended with the tech believing there was a tech memo on the era Fusion Drive I have. So they had it replaced.
- Interestingly, I learned that Apple does not make a way to unmount the fusion drive. The triage the techs need to use is an older OS version (including use of the old DU)
- This last time, the tech decided to kick the problem up a tier.
Suspicions
- I bet the BCA does not play nicely with Fusion Drive in 10.11.5. I think it is such a niche issue, it is not widely reported.
- I suspect there is a ghost partition(s) from my many failed partition attempts.
System Details
- 27 inch Later 2013
- 3TB Fusion Drive (1.66 TB available)
- El Cap 10.11.5
Aperture 3, Mac OS X (10.6.8)
