**Deleting the Windows EFI Boot Entry**

> This is the most accurate and I have succeeded!

First, you’ll need to locate the EFI partition, which is where your Mac stores information about what operating systems can be booted from your Mac. In the Terminal, type this command:

    diskutil list

You’re looking for a partition on your main hard drive called EFI.

    /dev/disk0 (internal, physical):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      GUID_partition_scheme                        *500.3 GB   disk0
       1:                        EFI EFI                     209.7 MB   disk0s1
       2:                 Apple_APFS Container disk1         500.1 GB   disk0s2

Once you find it, enter these commands one at a time:

    sudo mkdir /Volumes/EFI
Next typing:

    sudo mount -t msdos /dev/disk0s1 /Volumes/EFI

Replace /dev/disk0s1 with the correct partition you located using diskutil.


Typing Terminal:

    cd /Volumes/EFI/EFI

Continue typing Terminal:

    ls
At this point the list may appear as Apple, Boot, Microsoft.
Delete the Windows EFI Boot entry by typing this into the Terminal:

   

     rm -rf Microsoft
     rm -rf Boot


And unmount EFI, typing Terminal:

    sudo umount /Volumes/efi
MacOS High Sierra can type is:

    sudo diskutil umount /Volumes/efi

Restart your MAC and done!!!!
