Thank you, that worked. Does Mohave look to be better?

Mojave is still Beta. There is no way to tell if it will have the same issues, more or less. We should wait till the public release to see what is included in the final release.

I have a similar question.

I followed steps posted in this thread earlier once I encountered the same error message after windows failed to install. I was attempting to restart the install process and now it's saying I don't have enough space in my start up disk. I just ran 'diskutil list' and got the following results

Where can I go from here?

I'm very sorry to bother you too, but you seem to be the only hero able to solve this boot-camp issue.
my target is to install win10 on MacBook Pro splitting the disc 50/50.

Hi Loner,

First of all, I'd like to thank you for being so active these past few years helping everybody out on this issue! You are truly a godsend!!! However, I've read through several pages of this thread and I couldn't find a case the same as mine.

Here's my diskutil list :

I've only tried diskutil eraseVolume fat32 BOOTCAMP disk0s4 but the problem of "The startup disk cannot be partitioned or restored into a single partition" error still remains.

Any help is appreciated, Loner!

I have the same problem could you help me please

My problem that I have windows 10 installed by Bootcamp and I want to delete it

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.

What should I do?
