Question: please clarify

The msg fro Bootcamp just says "an error occurred while partitioning the disk. Please run Disk Utility ....."


What am I supposed to look for? I've run diskutil a number of times and have yet to get an error msg. So how do I fix something that is not reported? Why does the Bootcamp partitioning not provide a more detailed description of the problem encountered?


More importantly: how do I move forward from here? I have tried all the things suggested in this blog to no avail.


Please help.

Answer:
Answer:

We do not want to add a volume within the APFS container, but add a partition outside the container, on the disk. Click on the outermost disk and choose partition.

I thought I had joined that chat. well, obviously not.

Anyway, I have run through the suggestions in that chat with the exception of the past bit to no avail.

I have not done the "internet recovery logon" as I don't know what that is all about.


Again, the error message just says that there is a problem but not what it is. Then I'm supposed to check and fix my disk with the distil utility. But what am I looking for when I don't know the problem? And since no errors are reported then I would assume that there is no problem. But clearly there is.

Internet Recovery is explained in About macOS Recovery - Apple Support . It allows you to boot from Apple servers to diagnose problems, and re-install macOS, if necessary.


If you have High Sierra, there are known issues with the APFS file system it uses as the default.

Yes, I'm on High Sierra: macOS 10.13.3 (17D102).

I found the Internet Recovery and I have run all the distil tests against both disks and volumes without hitting any errors.

I've had Windows installed under Parallels for quite awhile and it has worked great.

My disk is Model: APPLE SSD SM0512G, Revision: BXW1SA0Q, Capacity: 500,28 GB

According to what I could find about the APFS issues, they do no apply to my SSD disk.

So what is the next step?

Revision: BXW1SA0Q

When booted in Internet Recovery, click on Utilities -> Terminal, and run


diskutil list


Select and Copy (Command+C) the terminal output, quit Terminal, start Safari (Get Help Online) and Paste (Command+V) the output as a reply to this discussion.

Boot normally, and try to create a FAT partition of the size you want Windows to be using Disk Utility. If you get an APFS error, you will need to use Time Machine backup/erase/restore to be able to partition and install Windows.

I followed your suggestion but got this message:

APFS Container Resize error code is 49153

I googled that and found an entry on the net about this error message at:

macos high sierra - APFS Container Resize error code is 49153 ...

https://stackoverflow.com/questions/.../apfs-container-resize-error-code-is-4915 3


The thread suggested removing local thin snapshots and turn off Time Machine. I did that and then reran Bootcamp setup - and it worked!!


Thank you for your help.
