File Copy Error


I am trying to migrate my Bootcamp Partition to a new mac and am getting a File Copy Error. Any suggestion on how to fix?

Supporting notes:

Using external storage device (formatted as exFat)

App: Winclone 10

Source: 2016 Macbook Pro 15” (intel) MacOS Monterey 12.0.1
Destination: 2019 Macbook Pro 16” (intel) MacOS Monterey 12.0.1

Attaching Log for additional info.

The EFI partition is full. Try mounting it and removing the backup files in EFI->Microsoft

Mount it by running :slight_smile:
sudo diskutil mount disk0s1


Following your advice I mounted the EFI partition and looked around for any duplicate files (In my case I checked ALL the folders not just Microsoft)

  1. Mounted EFI partition: sudo diskutil mount disk0s1
  2. Removed all items in EFI->Microsoft->Boot folder
  3. Removed extra items in EFI->APPLE-> (CACHES,EXTENSIONS,LOG,UPDATERS)
    *For step 3 I compared with another Mac I had kicking around to see what I deemed ‘extra’
  4. Restore Image

And for me, that did the trick.
