After misckicking on windows reset
So you started a factory reset then canceled out of it before allowing it to finish?
1.In that case, I would backup any files over the network if its still there or remove the hdd and place it into a working windows box to do it that way.
2. Insert the windows 10 disc/ usb and re-install the system... you have two basic options:
a. a fresh install, wiping everything and starting back at the blank windows or,
b. an advanced recovery install... basicly installs windows into the same folder as the old one and tries to replace the system files without buggering your other data.
The b option can save time but it just depends on how much stuff (
3rd party software will need a re-install before it works) is also on the system.
