Boot Camp not enough space when there is

Can you start a new discussion in Boot Camp - Apple Community ?

I have the same issue here, but mine shows even before I get to any partition option. As soon as I hit "Continue" on the first window I get the error message saying I need at least 40GB of free space. I currently have 332GB free on a 500GB drive!

Local snapshots simply cannot explain that in my case, as I barely have any. Apart from a clear install, what else can I try?

Hi, I am trying to install boot camp and I get the same error message that you did saying that I need at least 40GB of free space.

I saw that you followed these instructions "Local Snapshots first, and try before we look for other APFS-related issues. You also need contiguous disk space for partitioning." However I have no idea what any of that means.

Could you help me out?

Thanks

this is my output....help plz?

Also, is this a cut/paste error? 😕

Hi Loner T,

Thanks for all your instructions. I've deleted all my local snapshots, but I still get the message saying I don't have 40 GB of free space. What else can I do to free up 40GB of contiguous space?

Thanks!

Good news! I was finally able to partition the disc and install windows 10 successfully.

I was not able to move the dial beyond the 0.648 GB mark shown. When I put in the bigger number there, it would automatically revert itself to 0.648 GB.

Then I deleted the local snapshots again, ran first aid on the disc, and them ran the 'repair disc permissions task' on CleanMyMac 3. Restarted the Mac, and I was able to partition without a problem.

Thanks for your patience and all your help 🙂

Run

diskutil eraseVolume fat32 BOOTCAMP disk0s3

and run BC Assistant and click on Remove/Restore. Once it is restore back to a single macOS partition, re-run BCA and try to install Windows. The APFS implementation on High Sierra has many bugs.

The CCC snapshots should not interfere with the Bootcamp, unless they occupy unreasonable amount of space. The only snapshots you should be deleting should be com.apple.time_machine.* . Deleting the CCC snapshots will just bring them back, so it is unnecessary.

You may want to start a new discussion to avoid confusion, because you may have an APFS issue.

Thank you for the response and explanation.

I have reset the SSD drive to factory status and do not use Windows on the MB anymore.

Problem solved...😉

Yes, that is one way to address the issue. 😉

I noticed this thread when searching through a similar issue. I used Boot Camp last summer when I first got my current machine (have been using Macs since the early 90's) and successfully installed Windows 10 via Bootcamp with no issues whatsoever but it got to the point where I was running low on space on the Mac side and hardly ever using Windows so just removed Windows and the windows partition itself and carried on using my mac as normal. The space showed as available on the mac side and all added back up so all was well.

I've been having issues trying to put windows back on with boot camp saying that I don't have enough space even though I have more than enough. I am pretty sure that this is down to having an SSD and the way disk fragmentation works compared to your typical old fashioned spinning hard disk. I have 62GB free but Boot Camp says I can only create 40GB for windows (I can't make it any smaller than that) but it will only leave 4GB for the Mac side so if you do the numbers, that clearly does not add up. I should still have 18GB somewhere ...

You mentioned needing contiguous space to create a partition and I think that this must be the case. I don't use Time machine so don't have any snapshots taking up space and I also have about 1GB of purgeable space if that. All my Get Info's / Disk Utility / About This Mac etc etc all show the exact same space available so I am wanting to know if there's any way to make full use of the space I have left? I understand that the space is in fact there for normal files and that it must be the partitioning side of things but I have found APFS very flexible in that regard so far so I am disappointed with the issue I am having at present.

My next move is just a full format / zero all data / reinstall High Sierra from scratch from my pen drive, reinstall my Mac side and get it exactly how I want it, then go and do the Boot Camp thing and all will be well. It's just I'd rather not have to do that as my machine is running like a dream and I'm not (in theory!) running out of space.

Any suggestions welcome.

Regards

Dougie
