Boot in HD

Pandowisk

Hello, my GKMini arrived yesterday afternoon in the mail and I would like to ask, how do I boot the system from my HD? I just can't change the primary boot from the BIOS, because it says something similar to ''No media found" or something. I already have Windows 8.1 on it and would love to be able to make this work. Is there any other way? Thanks in advance !

P.S: I'm loving this pc, it's the best I've ever had!
P.S 2: In "My Computer" I can access my files normally that are on it

Hello there,

Are you using HDD with windows 8 system in it?  What is the capacity of it ?
Do you want to use dual system ?
