I’m trying to migrate an bootcamp partition on my internal HDD to an external HDD. On a mbp 2017 with touchbar. I’ve gotten so far that I get the inaccessible_Boot_device blue screen. I have a magic keyboard and wired it (after the setup is started, else it wont work) and got the files copied from the setup to the correct drive. This went succesful. But when I boot the drive I still get the inaccessible_Boot_device blue screen.
I’m lost, what should I do now?
