With an install disk or stick you should be able to do a clean install of Windows (just delete the current partition and make a new one if the format option during the install doesn't work).
Can you tell what exactly goes wrong?
Hello all, i recently bought a used laptop, but Unfortunately it has locked user account, and as a guest i have not full options to work on it.
I tried to format it but it's impossible, even with dvd disk or usb with Windows.
Can anyone give me some tips?
