I agree (in part) with "map9966's" answer, but instead of trying to blindly load the "last known good configuration", You really should try the Windows Startup Repair option. This option should also be located in the "safe mode" menu, which again access by repeatedly pressing F8 right after turning on the PC. Once you get to the menu stop pressing F8.
Using the arrow keys on your keyboard, highlight the choice which reads (something to the effect of) "startup repair". The PC then *should* "boot" to the start up repair mode. This mode is an automatic utility, and can take anywhere from 15 minutes to an hour, depending on the speed of your PC, the severity of file system damage and the underlying cause of your start-up loop. Let the utility finish, (again, this WILL take awhile.. go have yourself a snack, take a walk, watch some TV..) Once it's done, restart the PC.
In most circumstances (assuming the start-up loop isn't due to a hardware failure), your PC should boot up just fine. If you have any further questions, feel free to contact me!
