I recently started getting the error message "the server process could not be started because the configured identity is incorrect. Check the username and password" and I was looking up solutions, we'll I did a sys prep and I can't even boot up windows anymore. I have the option to change my timezone and stuff but it just resets if I try after about 5 minutes of loading. I just want to know how to wipe my hard drive clean without logging on to windows. I have Windows 10.
