Question: Bootcamp crash while creating new partition

Hi All,


I unfortunately had a system crash while installing windows 10 with Bootcamp. System locked up and had no option other than to turn off my mac. I tried to install Windows again and I now get and error and it falls over when the install process gets to the "creating partition" stage. The message is "Your Disk cannot be partitioned", "Please run disk utility to check and fix the error".


I have tried running disk utility to no avail. There is only on partition available "Macintosh HD" and I have run "first aid" as per disk utility with no success. The repair option is greyed out.


If anyone could shed some light on the matter I would be of that would be fantastic. Thanks.


Brad

Hi,


I run first aid in disk utility on the Macintosh HD and it came back as OK.

Tried to install windows via boot camp again and it came back with the same error.

Is it the small 1.1GB VM partition that is causing the issues ?


Thanks

The 1.1GB VM is a required part of APFS, which should not be removed. If you have run a Repair, can you run the following command and test BC Assistant again?


sudo tmutil thinlocalsnapshots / 999999999999


Also, run the following two procedures before your next attempt at Windows installation.
