I have installed Windows 10 on my Mac, which I deleted months ago (I am not sure if I removed it correctly?). However, when I now try to use bootcamp to install Windows 10 again, the error message prompts :

Unable to read the Windows partition
Boot Camp Assistant was unable to verify if the Windows partition contains a Windows installation. This may be because BitLocker is enabled on the partition. If so, disable BitLocker on the disk before removing Boot Camp.

How did you delete the previous Boot Camp partition? It is suggested to remove it via the Boot Camp Assistant, incorrect deletion may cause incomplete uninstallation so that it arises the error message: Unable to read the Windows partition when you try to use Boot Camp Assistant to install Windows on Mac.

Here’s how to fix it:

  1. Launch Terminal.
  2. Run the command diskutil list internal.
  3. Write down the identifier of the “Windows Recovery” partition.
  4. Execute the command diskutil eraseVolume free free disk0s3 to remove the encryption of this partition (e.g., the disk identifier is disk0s3.).
  5. Retry Boot Camp Assistant.
