Concur on just one EFI partition.  The Win10 ESP created by the 
MicroCenter install was only 100MB, and I had seen recommendations for 
300MB.  In addition, the tools I used to try to see how full the Win10 
ESP was looked like it was full.  Either I was using the wrong tools or 
misreading, as later looks at it showed only 21MB.

I had hoped to move the Win10 ESP contents to the Mageia5 ESP vfat 
partition, but copying them over did not work, and my attempts to use 
grub2-update to integrate the two ultimately failed.

Yes, I had booted with gparted two or three times trying to look at 
things.  No joy, perhaps because I was not familiar with gparted or the 
correct commands to use.
