Use another working computer to make a bootable USB using the program Download Assistant from Microsoft as described in my original post.
got it, thx
I have a four year old Acer M1-601 Windows 10 PC that I was not using and had in a box in my closet for a couple of years. I recently tried to turn it on so I could wipe any data on it and give it to one of my grandkids, but it would not boot because an OS file is corrupted.
