Boot Camp says "Unable to read the Windows partition"

I installed Windows 10 via Boot Camp Assistant and then rebooted into macOS. After that, I opened Startup Disk to switch to Windows, but it didn’t show the Windows partition. Now, I’m trying to remove the Windows partition. However, it gave me the error “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 can I fix this?

If Boot Camp isn’t doing its job, try using Terminal instead. You can erase the Windows partition with the following steps:

  1. Open Terminal.
  2. Run this command to find out the identifier of the Windows partition. diskutil list
  3. Execute another command to erase the Windows partition. diskutil eraseVolume free free disk_identifier. For instance, diskutil eraseVolume free free disk0s3
  4. Run Boot Camp Assistant again.
