Did you direct install from dvd or other? If you could give a little more detail it would be appreciated/I am running Windows 10 on MacBook Pro 15 in 2018 from an external TB3 storage (Akitio Node Lite + Samsung 970 EVO NVMe). You do need to allow external boot from "Startup Security Utility" under Recovery Mode.
I have eGPU plugged into the left side TB3 port and Elgato TB3 dock plugged into the right side TB3 port. The Akitio Node Lite is connected to Elgato TB3 dock as daisy chain. Samsung 907 EVO NVMe over TB3 does 2,500 MB/s sequential read and 1,800 MB/s sequential write on my benchmark using Samsung Magician.
If you you use TB3 external cases rather than USB 3.1 gen 1 or gen 2 external case, you don't even have to deal with Win2GO route for installation.
Yes. I installed Windows 10 directly without using BootCamp. Windows treats TB3 drives as internal drives for the purpose of installation, unlike USB drives which it treats as external drives.Did you direct install from dvd or other? If you could give a little more detail it would be appreciated/
Also experiencing the exact same thing with my 2018 Mini, did you investigate further or give up? I don't really want to sacrifice internal disk space just for occasionally booting into Windows.Thank you
I really appreciate the reply.
No Joy, Went straight to a boot loop to the recovery mode. Possibly a difference in the way the T2 works on the iMac pro Vs MacBook Pro
