I’ve tried to clone my Bootcamp partition (Windows 10) that’s currently running on an internal SSD of my Mac Pro 5,1 (Mac OS Mojave) to a new NVME drive that I installed via a PCIE adapter.
Drive is showing, everything works fine and completes without errors but when I try to boot from it, I’m getting a “No bootable device” error.
What I tried:
Convert to EFI Boot (successful)
Convert to Legacy Boot (successful)
Taking out the internal Bootcamp drive of course…
I can select the drive in the startup settings in Mac OS (I don’t have a bootscreen unfortunately as I have a non Mac GPU) and it shows as a normal external drive in Finder.
What am I doing wrong?
