Bootcamp Partition error - Disk cannot be partitioned

Hi,

When I tried to install bootcamp I got this error. I have tried lots of solutions, none of which have worked. Any help would be appreciated.

If this works correctly, but BC Assistant is failing, you are using a W10 1903 or later ISO file, which High Sierra cannot handle. If you split install.wim in .swm files, then High Sierra should work.

Run a SMC and NVRAM Reset, before your next BCA attempt.

Is this when you run BC Assistant -> Action -> Download, or trying to install Windows? Your Mac does not require any external storage. If you have anything connected, it will cause issues. You should also run a SMC/NVRAM Reset before your attempt to install Windows.

See https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/split-a-windows-image--wim--file-to-span-across-multiple-dvds for reference.
