Installing win10 over W\in 10

I tried to install win10 over win10, and I was able to get to 60% but
ten seconds afterr I moved the mouse so that the screen lit up again,
it crashed.

And even if it got to 99%, it says it's going to have to start
windows several times, and t here's n o way it coud boot even twice
in a row without crashing 30 seconds later for one of those times.

So I dug out the XP laptop to get back on line, and soon after that I
had a new plan:

Instead of installing win10 over the win10 IN the computer, I'll take
the drve out, put it in a dock, plug the dock into the XP laptop, and
run the win10 install program I made using the Media Creator.

That's one of the intended uses, isn't it? And since the XP laptop
never crashes, and iiuc it won't have to restart anything, since i'm
updating what is not the operating system in use, so it will go faster
too.

Will this work?

Will it work better with my win7 laptop?
(I'm still looking for the cord for that but I t hink I know where
it is.)
