Question: Having issues with partitions post-Boot Camp Assistant restart and on Windows 10 start up.

I'm having issues when it comes to the Windows 10 Set up page, post-BCA. I used to get...

  • Drive 0 Partition 1:EFI
  • Drive 0 Partition 2
  • Drive 0 Partition 3
  • Drive 0 Partition 4: BOOTCAMP
  • But had a bad .iso file for windows 10 so had to erase the partitions via BCA and try again. But now I'm seeing...

    • Drive 0 Partition 1:EFI
    • Drive 0 Partition 2
    • Drive 0 Partition 3
    • Drive 1 Partition 1:EFI
    • Drive 1 Partition 2
    • Drive 1 Partition 3
    • Drive 1 Partition 4:BOOTCAMP


    I tried to select Drive 1 Partition 4: BOOTCAMP, but an error occurs saying "Windows can't be installed on drive 1 partition 4 (Show Details). Click on details and get...

    - "Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS."


    Please help. Its been driving me crazy for the past week. Talked to Apple support for hours and even microsoft support.


    Not sure what is happening and why I can't get Windows 10 to be installed.

    This is on my iMac with Retina 5k running on the latest macOS High Sierra

    You have a 1Tb Fusion drive, which has an SSD and HDD part. The partition layout is normal for such a configuration. A reboot can renumber disks, so disk1 and disk0 are interchangeable.


    In Bootcamp Installer, you need to scroll using the right-hand scroll bar to find the partition named BOOTCAMP, format it, if necessary, and install Windows.

    I did those things previously and it gave me the error messages stated above. Here I'll show the screen shots too. User uploaded file

    After I try to format it then this issue happens.
