... it looks like I will have to reconsider your input throughout these forums about self-installing Windows rather than using Boot Camp. I don't recall how large the SSD is on these iMacs (mid 2013).
Now, in Windows (both in VM & in Boot Camp), Windows shows me only one (1) drive: BOOTCAMP (C:). So, as far as I can tell, I am trying to upgrade on the disk on which Windows is actually installed. I just wish MS would update the installer to ignore the offending hardware. :-\
The MBR that is created in most Fusion cases, has four entries (a typical case) and C: is a part of the HDD. The SSD in Apple Fusion drives is typically 120GB and you can see both disks in System Report -> SATA or diskutil list. In case of 3TB fusion drives, the disk space after 2TB is not included in the MBR, because there is no MBR utility which can address address beyond 2TB. If you trick it using an offset, it can go beyond 2TB as long as the size of the partition is less than 2TB.
The C: disk is part of the larger physical disk, and has it's own UUID as shown by diskpart or GPT utilities. Here is an example.
