Boot Windows on Mac using an external WD SSD 256

Hallo to everyone
Im trying to create a windows 10 bootable drive for my macbook pro2017
I have bought WD external SSD 256GB but it doesent seem to be compatible with any proccedure so far (i get blank screen when i coose EFI on Mac initial boot menu)

Have anyone tried to use a WD my Passport SSD as a bootable Windows disk for Mac? Do you know any tutorial or procedure that works with this drive?

Wish someone made it work cause I have bought it for that reason exclusively… :confused:

P.
