yes. disconnect the hard drive, install windows to the SSD, once windows is installed and updated shut down the system. reconnect the HDD and boot the system (you may need to change the boot order in the BIOS) from the SSD. once the system is set to boot to the SSD you can access the other hdd anytime as secondary storage.
you should be able to change the boot order in the BIOS and still boot to the HDD.
you may need to import the foreign disk (HDD) in the disk manager
