Hello,so I just bought this new sshd,all good I installed the ssdh and took out my hdd.I have my windows on my ssd.When I tried to open the pc I got the message "reboot and select proper boot device".And when I add my old hdd back the system boot.Even though I formatated the old hdd and disabled it the windows still doesn't wanna boot without the hdd connected.Can someone help me ?P.S:I've tried booting option in bios and all that stuff,didn't work.Thanks
