This ol' chestnut! I've seen it asked a few times, a lot of times.
I've done as it asked, a few times, rebooted etc,
Ran /sbin/fsck -fy in single user mode, its all good.
Thoughts? I've been struggling with this for 3 days.
Cheers!
MacBook Pro, OS X El Capitan (10.11.4), kernel issue
I'm not manually mounting it.
I am going through these steps:
Opening boot camp assistant,
it automatically finds the Windows ISO (from Microsoft.com). I click install (after adjusting the size a bit bigger: I'm only using this for one application)
After It spends a few minutes, 6-12 depending on its mood, 'downloading Windows support software' I believe it says, it locks up a bit, then I get this:
After the Failure, if I look at disk util, I see this (that second disk image isnt there until the attempt at bootcamp)
Thanks for your help,

What was the name of the volume that you ejected?
Can you run
diskutil repairDisk disk0
and post the output?

The ISO image should not be mounted, before BCA is started. If BCA mounted it, it should be fine.
The Repair Disk looks fine.
Can you create a FAT partition manually in Disk Utility, of the size you want Windows to be? If you get an error, please post a screen shot.
I'm having the same problem as the fella above and tried your terminal solution - didn't work. I am trying to run BCA on a brand new MacBook Pro which I've only had for about 2 weeks. Any other suggestions? It's surprising that this has happened on such a pristine machine....
Oh sorry, forgot that bit.
Apparently not... ugh
What is the year/model of your Mac and the macOS version?
Can you post the output of
diskutil list
diskutil apfs list
from macOS Terminal? HS is a very different animal compared to previous macOS version due to the introduction of APFS.
I HAVE ejected that volume at the end there that it creates before and tried again.
CCCOMA_X64FRE_EN-US... +4.7 GB disk2 (this shows up when I attempt the partition) was the volume I ejected
In Terminal, please run
sudo tmutil thinlocalsnapshots / 9999999999999999
and then retry the BCA. This is a HS issue.
Create a Time Machine backup, boot into Internet Recovery, erase your whole internal disk, restore your TM backup, disconnect all external storage unless BC Assistant prompts you for one and retry.
"An error occurred while partitioning the disk. Please run Disk Utility to check and fix the error."
