But isn't it "region locked"? I mean my tablet was in german. Dunno if it matters.

The thing is now i tried to boot from USB and i still get the same error. "No Bootable Device, Hit any key". Could it be a HDD problem or something like that?

I had the same issue it's the bit locker drive encryption I had to go into pc settings - PC and devices - PC info scroll to the bottom turn Device Encryption off and it worked ok
