Two operating systems presented. The second is formatted.
Hello! It looks like you're trying to switch between two operating systems on your new SSD. Since you've formatted the old SSD and installed Windows 8.1, you might want to check if the old OS can be reinstalled or if you need to create a bootable USB for the previous system. If the SATA port is still recognized, you could try booting from that drive to restore the earlier OS. Let me know if you need further guidance!
You didn't need to disconnect all your existing drives when installing Windows on the new SSD.
Open msconfig, go to the boot tab, and edit your boot.ini file. Delete the existing OS setting.
