Did you find a solution for this?
I noticed when I first installed a Crucial M4 SSD in my Z77-D3H, it was not seen in the Boot Order Priority list either.
Then I partitioned the drive with gparted-live, created an EFI system partition and made the EPI system partition bootable. Then I could see the Crucial M4 SSD as a bootable device.
I'm guessing your Samsung hard drive doesn't have a bootable partition, a gpt, or a master boot record.
In any case, you should be o.k. to go ahead and load Windows.
