Stuck in Loop

PC keeps shutting off & back on while attempting to configure, but will not complete the configuration beyond 35%. No matter what I attempt to do, pc will not allow me to do anything because it is stuck in this loop. F8, alt F10, nothing enables getting out of loop. I want to re-set to factory settings. Windows 7 Professional, 64 bit.

 

My computer will not allow me to download or access anything. It just keeps turning off & back on indicating it is configuring Windows , but does not complete configuration of Windows updates beyond 35% before it does the same thing over & over again. It will not get past doing this in safe mode, safe mode with command prompt, won't do anything different. I can get into Del F12, but don't know hat option to select.

 

Terminator the computer will not let me get to the repair all in one tool. Where do I find it? It will not let me get anything but the configuring windows & shutting off & on over & over again.

 

Is it possible to download the tool on a removable thumb drive and then load it on the computer which is stuck in the loop?

 

Arie, thank you so much. I've done this numerous times. I do not have a disc to insert . My Windows 7 was purchased online and installed via online by a Microsoft tech, a couple of years ago. I have the product key, however that is not an option. The only options given are:
Start in Safe Mode; Safe Mode with Networking; Safe Mode with Command Prompt; Start Windows Normally, which I've tried all except the Networking and the computer just goes right back into the loop.
Other options I see after these are:
Enable Boot Logging; Enable low-resolution video 640x480;
Last Known Good Configuration - advanced (tried);
Directory Services Restore Mode (tried; I get the message "failure Windows configuration update, converting changes);
Debugging Mode (tried);
Disable automatic restart on system failure (tried);
Disable Driver Signature Enforcement;
all which I've tried the computer still goes back to looping of configuring 35% complete, the computer then shuts down & restarts over & over again doing the same thing.
Absolutely No other options are given.
