factory reset gone wrong

[mmjaved1]

I had window 7 on labtop which I had upgraded to window 10, my computer was gone very slow so I reset it to factory setting but in the middle of reset I got an error message ( can not delete some of the files try reset again)

I turned off my computer and tried to restart now it is giving me message operating system cannot find try restart computer.
I have tried recovering with windows USB but it is not letting me restore or repair . Please help ?

You should make a windows 10 USB install and try repair then reinstall. Only way to get back to windows 7 is revert
