Q: Cannot be partitioned?

Hi,

 

I'm trying to install Windows 10 on my late-2013 Macbook Pro retina. I am able to create the install drive and download the software, but my computer gives an error when I try to use bootcamp to create a partition. I'm trying to give Windows 32GB of my 512GB SSD. I tried using Disk Utility first aid, but that's hasn't helped either.

 

Thanks in advance.

MacBook Pro (Retina, 13-inch, Late 2013), OS X El Capitan (10.11.6)

    Does BC Assistant create the USB Installer successfully? 32GB is too small for a working W10 installation.

     

    From How to install Windows using Boot Camp - Apple Support,

     

    • At least 55 GB of free disk space on your startup drive

     

    If it does not let you use more than 32GB for Windows, you have a different issue.

    No, it will only let me partition up to 36GB

    No, no errors. I was able to attempt a 55GB partition, but it still could not be completed.

    Can you boot into Internet Recovery (not Local Recovery) and run Utilities -> Terminal and execute the following command

     

    diskutil repairDisk disk0

     

    Use Command+C (Copy) to copy the output, quit Terminal, start Safari, and Command+V (Paste) as a reply on this discussion.  If you are asked about the EFI Partition, enter 'y' (or 'yes').

    Please boot normally and retry BC Assistant. If it fails, can you boot normally, and post the output of the following Terminal commands?

    I assume BC Assistant failed in creating the partition.

     

    1. Run Applications -> Utilities -> Console logs and in the top right hand search box, type 'disk' and search. Look for any errors.

    2. As a test, in Disk Utility, try to create a FAT32 partition of the size you want Windows to be. Do you get any errors?

    Yes, errors for both.

    This should not be required, but as a test, boot into Internet Recovery, and run the following command

     

    diskutil cs revert A35D09C8-177A-46C5-B870-B27114E49791

     

    This will make your disk a regular HFS+ partition. Now run BCA and retry. If it still fails, you have a fragmented disk.

     

    Please see the steps in Re: failed windows 8.1 installation through bootcamp to backup/erase/restore your OS X partition and then run BCA and try again.

    Ok, the Internet Recovery did not work. Will the directions in the link work for a Windows 10 installation?

    The link allows you to backup/erase/restore OS X only. It is not supported for Windows backup/restore.
