"Reboot and Select Proper Boot Device"-Message after Installing Win 8 on SSD

[SouthofHeaven]

Hey guys,

I just installed Win8 on my Samsung 840 Pro, but it keeps booting to my old HDD (win 8.1). I changed the boot order but keep getting this message.
But when I enter manual boot with F8 everything works just fine.

What can I do to fix this? thanks in advance.

you need to remove the os completly and start over when installing os to a new drive

couldn't I just unplug the old HDD while installing? when I'm booting up manually I can choose between both os' - the win8.1 on the old one and the win8 on the new one.
