I really struggled to install Windows 10 via Bootcamp on Catalina, and after a full day of every known troubleshooting tips I could find I not the bullet and formatted the HD to Mojave and bang! Straight in. Windows 10 and Mojave. Now, what I am left with is 2 of the secure areas that Catalina creates for the OS. They are only in the KB in size, but here they remain. I’ve tried un-mounting the drives and deleting them but they pop back. Can anyone shed some light please? Thank you in advance.
