So if I understand it correctly, you press option 4 or 5 (with networking), and the machine boots but basically does not present you with an option to login so you can't get into safe mode.
So bottom line is if you boot normally then you don't get any opportunity to login and if you boot through trouble shooting and try to get in that way you are also not presented a login panel.
So really the problem is no login in screen presented for password entry. Please confirm.
Okay, now we are making progress. Do you use a local account or a Microsoft account?
When ever I use a local account on a device I create an alternate admin. I don't use it but in case of corruption I can use it to sign in. Is there another admin account you can use? Is there any other account?
If you use a Microsoft account, and you are using safe mode with networking, I think option 5, then on another PC go to microsoft.com/account and try to sign in there.
If it won't let you, you will have to go through password recovery, you know, "I forgot my password". Once you have your password squared away, and you may not have a problem, but if you did you can head back to machine and login.
Please post back. answer to all questions. Thanks
