Q: Yosemite partition issues (greyed options)
Running:
Hard disk: 3TB Fusion drive
I recently upgraded to YOSEMITE and then after decided it would be useful to add WINDOWS 8 on bootcamp for various reasons.
What I did:
- Partition my 3TB Fusion drive to 2.68TB YOSEMITE / 318 MB WINDOWS
- Format the new WINDOWS partition in NTFS (using paragon software)
Result:
- My new partition seems to have formatted (itself) to Mac OS journaled (how/why?)
- Now all options to resize or delete partitions are grey out. I can't change anything
What have I tired:
- Booting into disk utility (command-R) to access the drives, but all options are still greyed out
- Tried reverting the disk as per some threads, but have failed (please see disk info below)
Haven't yet tried boot to an external Mac OS build to attempt to change/influence the partitions as I have read a thread that didn't yield results with this giving a sort of checksum error. I'm at a loss, any advice would be gratefully welcomed!
iMac, OS X Yosemite (10.10.2), 3TB Fusion drive
