1TB USB-HDD, Next-Butten stays gray while trying to install win10

[admin]

I'm trying to install Windows 10 on a 1 TB WD-Elements drive.
After selecting the drive i dont get any dialog asking if i want to go for MBR or whatever. after selecting any Partition it still doesnt work (whether primary, raw or no partition at all) the Next-Button stays gray and i cant install the OS to it.

Are there Any Solutions?
If i should send something, pls tell me exactly what to do

Thanks

You need to manually create the partitions if you are using an external hard drive to create Windows To Go, please read the setp 2 of the user's Guide carefully:
