OK, now I understand. This is what I would do.
MAKE A BACKUP OF ALL YOUR ESSENTIAL DATA - then:
Just leave everything like it is and do the in place upgrade to Windows 10. Run setup.exe from your Windows 10 install media from within your existing Windows 8.1. Once you have a successful upgrade to Windows 10 and it is permanently activated then move on.
Next you will want to make a bootable USB, CD or DVD of MiniTool Partition Wizard. Or looks like you can use Paragon if that is what you have now. Before the next step it is critical to make sure that you can boot from your Windows 10 Install USB or DVD - boot from that, select your language, keyboard, click install now button in the center, then click Custom Install. You should see a list of your partitions. Stop and cancel, you know the Windows 10 install media will work.
Now boot into your partition manager program - whether it be Paragon or Partition Wizard. What I would do is delete every partition except for the two data partitions that I want left. Then move those partitions to the end of the disk. You can resize them then if you want. Once you are left with nothing but the two data partitions at the end of the disk, properly exit out of the partition program making sure it has completed all of the operations.
Now, boot from Windows 10 install. Do like you did before, select language, keyboard, click install now button in center of the screen, click on custom install. Now just point it to the big unallocated space at the beginning of the hard drive and let it install itself there, creating whatever partitions it wants to in the process. That should be it.
