Move an internal Windows 10 bootcamp SSD to external USB enclosure?


Hi- I currently have a second SSD in my 2010 iMac. I’m preparing to move to a 2012 iMac and will be running both my current SSDs in an external USB enclosure- the 2012 had a 750gb Nvme SSD I’ll be booting off of.

Will this cause any issue with Windows 10? Will I have to prep the drive in any way to get Windows 10 to continue booting off of this drive once it’s connected via USB 3 rather than Sata II?

I’ll make a Winclone backup first of course. Thanks in advance.


I forgot to mention I’m running Windows 10 enterprise- which is generally more forgiving when changing drives or configurations.

The following external USB-C hard drives where used:

Both external SSD were connected via a USB-C to USB-C cable, or USB-C to USB-A depending on ports available on the Mac.
