You haven't formatted the drive yet, that's why you don't see it. Now here's another problem I think that needs to be brought up to your attention... Since you had both the SSD and HDD in your system while installing, if you go to Control Panel -> System and Security -> Create and format hard disk partitions to enter Disk Management you'll see a 100mb partition on your F3 labelled "System Reserved". This is the boot files for Windows. I would recommend reinstalling Windows again with only the SSD plugged in to ensure all boot files go to the SSD. Then once you've done that you can plug back in the F3, go back to Disk Management, delete the 100mb partition on it and create a new partition. Then you'll see the drive in My Computer.
