Hi. My name is***** you for your question and the opportunity to assist.
You may not need a disk. On your login screen does it display your email address
in addition to your user name?
If your email address does not show on the login screen the computer would need to be reset.
This would re-install Windows and overwrite any personal files but would get you back in
to the machine.
Good morning Stephen. Do you still need assistance with this?
