Why do people ...
... think it's fun to attempt to "reinstall Windows" when they don't know what they're doing??
Around 99% of the time it's unnecessary, around 99.99% of the time it doesn't actually solve whatever problem you thought you had, and as you've discovered a fair proportion of the time it just fails if you haven't prepared properly leaving you worse off than you were before.
Yes I know that some of the robots on the end of "technical support" lines have "reinstall Windows" somewhere in their scripts, but you don't believe them surely to goodness????
Here's the true story about reinstalling Windows:
(1) Don't, unless you know exactly what you are doing.
(2) Don't, unless you know exactly why you are doing it, you know exactly what the problem is that you're trying to solve, and you have cast-iron proof that intalling Windows will solve it, and you have cast-iron proof that nothing else will solve it.
(3) Pay a professional to do it properly.
(4) Fix the real problem first ... then you won't have to reinstall Windows.
And finally, if you choose not to follow any of the above advice at least follow this one please:
(5) Just don't.
