problems with rescue disk

I created a rescue disk on USB to remove virus’s found during a diagnostic run at a computer service which was doing a memory upgrade. The Advast disk found several virus’s but could not fix them. It told me that I needed to reboot my computer. The tool evidently installed or changed something on the computer. I do not remember my local password. I haven’t logged in locally for years. Now I can’t get back to my Windows 10 login, it keeps trying to take me to the fix tool. How do I get rid of this new login screen and back to my windows 10 login.
