You already have an unallocated 400MB System partition on Disk 1
from command prompt (admin)
Diskpart
select disk 1
create partition primary
format quick fs=ntfs label="SYSTEM"
assign letter="S"
active
exit
Bcdboot D:\Windows /s S: /f BIOS
And I assume D is the SSD OS you want to Boot, so you can delete the C OS you are now using from the HDD..
