Startup repair loop cannot get into safe mode

I have a dell 9300 its older (2005) but has worked fine until yesterday. Nothing new added to it. Running windows 7. Dont have disc. Anyway my wife turned it on, it went to startup repair and restarts itself periodically. I have tried to use F8 on startup but it will not do anything just returns to Startup checking for problems then restarts again after a few minutes.

Oh I was able to use F12 and ran diagnostics and it says everything passed So HD is fine.

I had it installed by a repair guy several years ago. I did not get disk. before it rebooted again, i was able to chek the repair details.. Last part of the report read
Root Cause found
System volume on disk is corrupt
repair action: File system repair (chkdsk)
Result: Completed succeddfully. Error code = 0x0
Time Taken = 76547 ms

btw i am using another computer to post this as i cannot do anything on the other one. I dont know how i would use the download on the other computer to give you that information

repair details this time:
Boot Manager failed to find OS loader
Repair action: File repair
Result Failed Error code 0x490

repair action Boot configuration data store repair
result Failed error code 0x490

Repair action Sytem Restore
Result completed successfully error code 0x0

in the loop there is a point where is says it will restart the computer in ... seconds
there is a place to click to "see" repairs.
Those are the messages

and no it is still looping and i cannot do anything except F2 and F12
F8 will not work

ok i am working on it. I googled the error code. There is a repair for that code but i need to get into the OS in order to repair it. So hopefully this will allow me to get there
