Dear gents, recently it appears a problem for my rig. After restart it enters directly in bios and it dont see the memory stick. If I restart it again the same story, bios again. I tried the memory stick on another computer and it starts properly. I tried also to put again the img on the memory stick. It did boot properly first time but after i restarted again the same story. I am using a Gigabyte GA-Z270P-D3. Do i miss any setting or there is something else?

Thank you!
