Restore is stuck at "Extracting file data"

I have a late 2013 Mac Pro with a 256GB internal SSD (MacHD). I am trying to transfer my BOOTCAMP partition to a new 1TB SSD.

MacHD is running Mojave on the Mac side, and Windows 10 Pro on the Bootcamp partition.
1TB SSD is running Big Sur and installed internally in the Mac Pro.

I ran the bootcamp assistant. The system booted to windows and got to windows setup. The installation wouldn’t complete because Windows setup said the GTP files are not in the recommended order. Gave me the option to install anyway, but I canceled out. Figured since the Bootcamp partition is setup up on 1TB SSD I’d just transfer the old install using Winclone 9.

In Big Sur I use Winclone 9 to create the Winclone image. Used restore to place the Winclone image onto 1TB SSD in the bootcamp partition.

Process runs to ~90% and stops while “Extracting file data.”

I’ve seen forum posts ranging from waiting 3 hours to 12 days to having to jig around with reformatting something.

Not sure what to do at this point. Please help.


Thanks Rod. Seems like a similar issue. Here is my Winclone Log and DiskUtil List after running Winclone.

after stopping Winclone - Terminal: DiskUtil List

0: GUID_partition_scheme *960.2 GB disk0

2: EFI ⁨NO NAME⁩ 104.9 MB disk0s2
3: Apple_APFS ⁨Container disk1⁩ 449.0 GB disk0s3
4: Microsoft Basic Data ⁨OSXRESERVED⁩ 10.0 GB disk0s4
5: Microsoft Basic Data ⁨BOOTCAMP⁩ 501.0 GB disk0s5

/dev/disk1 (synthesized):

5: APFS Volume ⁨OWC_SSD⁩ 15.0 GB disk1s5
6: APFS Snapshot ⁨…⁩ 15.0 GB disk1s5s1

in macOS EFI must be in the beginning of the disk
2: EFI ⁨NO NAME⁩ 104.9 MB disk0s2 is incorrect

/dev/disk2 (external, physical):
0: GUID_partition_scheme *240.1 GB disk2
1: EFI EFI 209.7 MB disk2s1 is OK
2: Microsoft Basic Data Windows 239.8 GB disk2s2

So I would need to move “2: EFI ⁨NO NAME⁩ 104.9 MB disk0s2” to “1:EFI ⁨NO NAME⁩ 104.9 MB disk0s1,” directly after “0: GUID_partition_scheme *960.2 GB.” Am I understanding that correctly? Should the “1: Microsoft Reserved ⁨⁩ 16.8 MB disk0s1” be moved to “2: Microsoft Reserved ⁨⁩ 16.8 MB disk0s2” or removed all-together?

How do I do that? I’m not sure how to re-order partitions in Diskutil, or even if “re-ordering” them is technically the named of the required operation.

Thanks for your help by the way.

I am not sure how to fix it NOW
you did not prepared this disk by Mac’s Disk Utility
i think you did it by Windows tools
there is no 1: Microsoft Reserved ⁨⁩ 16.8 MB disk0s1 at Mac

Yes. I think this happened during the windows setup through bootcamp assistant.

I may need to address this through diskpart in Windows.
I don’t know what the “microsoft reserved partition” is or what will happen if I remove it.

you dont need it if not using Dynamic Disks

Ok great. I’ll probably try removing that partition and see how things go from there.

Have you figured out what is wrong with the EFI disk on your system. I’m wondering if we have different problems that overlap or if the real problem on both our systems is related to the EFI disk.

The EFI partition is always created as the first slice when using Disk Utility or Boot Camp assistant. If you use Windows tools to format the disk, it can add the EFI partition at another location. Winclone currently expects it to be at the first slice.

Thanks Tim!

Can you tell me where to go from here to get the disk formatted properly?
How do I get the EFI partition to be located “at the first slice.”

once again, prepare disk by Disk Utility only
not other and 3rd party tools

Based on my test is visible that you should create first windows partition with Boot Camp assistant by selecting the size and even windows iso, after the restart, just stop the installation of windows and boot again in macOS and then open Winclone and select newly created partition and restore it

You dont need to do anything with bootcamp assistant
erase disk with Disk Utility, scheme GPT, format FAT32, then restore Windows by WinClone, is it so difficult?

Not when you put it that way. But up to this point I had no idea that I didn’t need to use bootcamp assistant with WinClone.

The problem as I understand it now is the existence of the EFI and the Microsoft Reserved Partition. Simply erasing with disk utility does not remove the EFI or the MRP. That is actually proving to be rather difficult for me to resolve. I’m currently in the process of rewriting the partition table through the use of terminal, while booted in recovery mode from a version of OSX that will recognized the SSD drive. That’s requiring a number of detailed and time consuming steps, reformats, and fresh installs of OSX.

I’ll update if it works and I find a solution.

Erasing will remove all the partitions and recreate EFI
if you erase entire DISK as written , not separate PARTITION

I wish that were the case. However, as I’ve already written, that did not work. Erasing the disk in diskutil did not remove the Microsoft Reserved Partition.

Removing the MRP has required the more lengthy steps I described above.
Reworking the GPT as described in this forum has removed the MRP.

Still a work in progress and I’ll keep updating if I find success.

Erasing the disk removes all partitions from disk, it is obvious
diskutil partitionDisk diskX 1 GPT fat32 WINDOWS R

Obvious? Not to me. But I would say that when clearly explained the process is not very difficult. So thank you for offering the Terminal command line.

This reformatted the harddrive. However I cannot install OSX on a fat32 formatted SSD. So I

  1. Booted to Bootable USB of Big Sur install
  2. Reformatted to MacOS Extended Journaled
  3. Installed Big Sur
  4. Used Disk Utility (GUI) to create a windows partition ExFat
  5. Ran Winclone 9 to restore my winclone image (called BOOTCAMP)
  6. Operation was successful.
  7. Downloaded Drivers from Boot Camp Assistant
  8. Inserted Drivers using Winclone.
  9. Rebooted with Command + Option
  10. BOOTCAMP is not selectable.
  11. Rebooted into Mac OS. Set BOOTCAMP as the start up drive
  12. Boots to windows logo.
  13. Circle dots spin beneath the Windows logo
  14. System restarts and boots in to Windows in a never-ending cycle of Windows reboots.

Now what? Does anyone know where to go from here?
