Startup repair loop error

[usna13]

Hello,
I have looked into the startup repair loop problem a bit and have tried the advanced repair option but when it prompts me for a login and password, it only gives the option to log in as "updatususer". I would really appreciate some help with this problem! Thanks in advance.
