Q: Unable to Overcome error - "The Startup disk cannot be partitioned or restored to a single partition"
Hello!
I am attempting to install Windows on my iMac (late 2013, running 10.11.6) with no success. I have created the ISO on a flash drive, but when I attempt to use the Boot camp Assistant, I am remitted to the following screen:
I did my best to investigate solutions. The cause, per apple's support discussions, is that there is an alternate partition preempting (stopping) the boot camp assistant from partitioning the hard drive. I investigated the partitions on my hard drive after disconnecting all peripheral devices and found this:
This shows the main partition: Macintosh HD, the bootcamp partition: BOOTCAMP; and 2 unknown partitions: "Apple HDD ST100DM003 Media" and the same ***M004. I was able to delete the first Apple HDD ST100DM003 partition, and ran first aid on the fusion drive after the second one would not delete. I also cannot delete the boot camp partition. I continue to get the same message when I attempt to install windows on a partition of the Fusion Drive using Boot Camp Assistant - "The startup disk cannot be partitioned or restored to a single partition".
Any suggestions??
iMac (27-inch, Late 2013), OS X El Capitan (10.11.6)
