I'm trying to use Boot Camp Assistant to install Windows 10 on my IMAC (Catalina). It keeps getting stuck at partitioning disk (not unresponsive, just not progressing). Any solution please?
iMac 21.5", macOS 10.15
As a test, in Disk Utility, create a MSDOS-FAT partition of the size you want Windows to be. This partition can be deleted later. Also, do you have any external peripherals (except Keyboard/Mouse/Trackpad) connected to the iMac?
We need to remove the highlighted entry which is 0 Bytes in size. Do you know how it was created? Can you post the output of
sudo gpt -vv -r show /dev/disk0 (or disk1)
Use the appropriate disk[0,1] in the command which points to the 27GB disk.
If you are able to boot normally in macOS using the internal disk, disconnect the external disk, and check the output of
sudo fsck_apfs -n -l /dev/rdisk2
If you do not see any errors, run a SMC and NVRAM Reset and try to install Windows.
Disable SIP temporarily and retry.
Can you boot into Internet Recovery (not Local Recovery) to correct the GPT. The other option is to install GPT Fdisk.
Can you post the output of
sudo fsck_apfs -n -l /dev/rdisk2
from macOS Terminal?
Can you post the output of
diskutil apfs list
DU should not use the 27GB 'faster' disk. It should use the 'secondary' 1TB disk. Your APFS partition is correctly configured, so DU is making the incorrect choice. Did you specifically ask DU to chose the 27GB 'faster' disk?
Try
sudo gpt -vv -r show /dev/disk0
or
sudo gpt -vv -r show /dev/disk1

As a test, create a FAT partition of the size you want Windows to be and check for any errors?
I do have an external MIC connected as well.
It didn't work to create a new partition:
