Can't seam to find this icns file? Is that on EFI volume that was used for this tweak? Sorry for so many basic question in this thread, but I am no expert on this.

Thanks! But the restore of orginal EFI is not perfect/complete, I still see the GRUB message when booting Windows, even tho there is no error. And at boot chime the partition was renamed to "Boot EFI" insted of "Windows 8.1".  Can this be even "repaired" or I need new bootcamp installation?

I Have problem with GRUB. When i wrote command grub> ls , He give me this: (hd0) (hd1) (hd1,gpt4) (hd1,gpt3) (hd1,gpt2) (hd1,gpt1) 


So, when i wrote command diskutil list, my mac show me this: 

/dev/disk0 (internal, physical):

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *251.0 GB   disk0

   1:                        EFI EFI                     209.7 MB   disk0s1

   2:                  Apple_HFS System                  151.1 GB   disk0s2

   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

   4:       Microsoft Basic Data BOOTCAMP                99.0 GB    disk0s4

I can boot into windows 10 using iGPU on internal display now. However. I realise once the eGPU is in used, the whole windows will hang. The screen will just freeze. For example when i use "dxdiag" to check the display information. Or when i connect the external display. It seems once the eGPU is being switched to or used, it will freeze the whole system. Any idea why? I am using nvidia 1060 on windows 10 on my Macbook Pro 15 inch (mid 2014) model.
