Hi, I just installed and set up Bootcamp (Windows 10 Pro) on my 16-Inch MacBook Pro yesterday, and after getting it all set up, I purchased WinClone to migrate this over to an external disk, thus freeing up 100GB of space on my Macbook’s internal SSD.
I followed the instructions on the guide, but I cannot get windows to boot from the external disk. I cannot get past the various windows blue screens / Stop Codes.
I sometimes get the Recovery option, but when I attempt to boot in Safe mode or with boot logging, the same thing happens - Windows appears to be starting, but then the computer restarts, Apple Logo appears and it boosts into macOS.
I have tried the ‘Make EMI bootable’ option in WinClone.
I have not yet wiped the original BootCamp partition, incase something like this happened. I
Here’s what I’ve done:
I have partitioned a 256GB external SSD in USB 3 enclosure using Disk Utility to have 2 partitions, one MacOS volume, and a 100GB ExFAT partition (My Bootcamp partition is only 15GB, so should be plenty, as I’m only using windows for a very limited number of things)
It wasn’t allowing me to do a ‘volume to volume’ clone, so I performed a ‘Create Image from Volume’ on my BootCamp disk.
Once completed, I restored this image to the ExFat partition on my 256GB SSD.
When It failed to boot, including in safe mode, I relaunched WinClone and performed the ‘Make EFI bootable’ operation on the new External BootCamp (WinCloned) volume.
I have injected the AppleSSD driver onto the External BootCamp (WinCloned) volume, but it still will not boot.
I lost 5 hours yesterday trying to get this to boot.
When I start up the Mac holding the option key, the wincloned volume appears as “EFI”.
As I spent a while installing custom graphics drivers and other setting up, and considering that I am booting the migrated Win10 volume on the same computer, I didn’t think it was necessary to use ‘Sysprep’, as from what I read, it removed any custom drivers, which shouldn’t need removing.
Any help would be much appreciated,
