Booting from an SSD attached to USB fails

[Argomeniam]

Hi Everyone

I'm relativly new to true nas and i'm looking forward having fun with it.

I wanted to give Scale a shot but ran into the following problem. I have an HP Microserver Gen8 4 Bay. The 4 Bays are planned to be used as storage. So i have attached a SSD to the internal usb port as the systemdrive. Installation was not a problem but after that booting fails stating that this is a true nas data drive and the system is halted. I'm sure this is only a little mistake i'm not seeing.
Same config worked like a charm with true nas core.

Sorry for my poor english and thanks in advance for your help!!

You have to set the boot order in the bios

I'm sure i did that because it was not a problem with core but will double check that.
That you for your answer!
