I have three questions now:

1.	Will Windows 10 install itself in the unpartitioned space? I've attached 
a screen shot of gparted to show the current layout.

2.	What will happen to the UEFI kernel entries in /dev/nvme0n1p1?

3.	Those entries include some left over from experimenting with other 
distros. How can I manage the entries and purge the ones I don't need? 
"Bootctl remove" ignores them.

Thanks everyone for your help so far.

I don't want to install into a VM, because my main reason for installing 
Win10 is to be able to run an occasional firmware update program, none of 
which, it seems, run on Linux. Of course, it should also help me get up to 
speed with the M$ world.
