I tried installing windows 10 on mac but some sort of error occured and since then boot camp had been removing the partitions for hours. So I ran "diskutil eraseVolume fat32 BOOTCAMP disk0s3" on terminal as mentioned on another thread: Stuck on "please wait while Boot Camp Assistant is removing the partitions it created". Then I closed the Bootcamp window and reopened. Now that I click "Continue" on the Introduction, it prompts: "The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows."
I no more want to install Windows. Please help me restore the storage used up for windows.
Thanks in advance.
