I'm not certain.

If you only have the SSD connected, there should not be an issue when you upgrade. If have other drives connected, the install might use one of those for the boot code - this is not an optimal disk configuration. You want the System and Boot partitions on the same drive. Since your boot code is on the Windows Drive, no problem there.
I'd like to see your Disk Management. If you already downloaded the custom Management snap-in, you don't need to download it again. Just launch dmDskmgr-vd in the location you previously saved it (yes, you can still open the zip folder and launch it from inside)
Double click dmDskmgr-vd.zip to open the compressed folder
Double click dmDskmgr-vd.mmc to launch the custom Disk Management console
You'll get an output similar to this:
Press Alt+PrtScn to grab a snapshot of just the Disk Management window
Open Paint and Ctrl+V to paste it, then save the image
Attach the image to a new post.
