I keep running into this error when running Boot Camp Assistant:

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.

Here is my diskutil list output:

Simply remove the Microsoft Reserved partition by entering the command given below.

diskutil erasevolume free none disk0s2

Restarting the Mac afterwards would probably be a good idea.

Note: When installing a UEFI booting Windows, Microsoft states there needs to be a Microsoft Reserved partition. However, I have never seen the Boot Camp Assistant create this partition when employed to install Windows.
