WD officially states that you need to use Red (EFRX series drives), to boot the device properly, but you can also clone the drive and it will work just fine. Just replicate the first 22 partitions, and create the last one (23rd) manually with the maximum size that you have left on the drive. It should work. (It did in my case).
You can do that with Diskgenius (https://www.diskgenius.com/).
