Are you aware the boot system is on the 1TB drive
I would make the OS partition (SSD) active in Disk Management. Remove the 1 TB drive and run Startup Repair 3 times. This will set the boot system to the SSD.
All I might suggest, if you do not believe me, is to disconnect the 1 TB drive and try booting.
What type of drive is the smaller drive?
Hard to explain the end results, but in fact, the boot files are on the large drive.The 1 TB drive wasn't even CONNECTED when I installed windows on this machine.

My first suggestion still holds. Do a Startup Repair on the small drive after making that partition active.
Did you ever find out what was filling up your large drive? Recycle Bin empty?
I use up about 600-750GB of this drive a week in video editing and then removal of old video after being archived.
