Your disk schema is a bit wonky - this happens a lot when people put new drives in machines.
You might be able to quickly resolve this by disconnecting the 2nd HD, restart with ONLY the SSD connected.
If you haven't already, download the ISO instead of upgrading this pc in the Media Creation Tool. That way, if it fials, you have the install media and don't have to download anything other than Windows updates.
You won't need to put the ISO on a device - when the download completes, press the finish button
See: Download Virtual CD-ROM Control Panel from Official Microsoft Download Center
for Win7 only ... Win8 has native mounting support.
edit: I could not get the above tool to work, so I removed the suggestion from this post.
Use the above tool to mount the Win10 ISO as a drive, then run setup from that mounted drive.
If the upgrade still gives you trouble, try this with ONLY the SSD connected.

Pay attention the the yellow tip box at the end - you might have to run the repair three time.
