Windows did not start successfully

I receive the following message when I try to start Windows XP:

"We apologize for the inconvenience, but Windows did not start successfully.
A recent hardware or software change might have caused this.
If you computer stopped responding, restarted unexpectedly, or was
automatically shut down to protect your files and folders, choose Last Known
Good Configuration to revert to the most recent settings that worked.
If a previous startup attempt was interrupted due to a power failure or
because the Power or Reset button was pressed, or if you aren't sure what
caused the problem, choose Start Windows Normally.
(these are the choices
Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt
Last Known Good Configuration
Start Windows Normally"

Regardless of the option I choose, the same screen appears time after time.

I have tried to repair Windows XP through the Recovery Console on the CD and
I have tried a repair installation. I have rebuild my boot.ini. The results
continue to be the same.

I have now installed Windows XP on another partition on a second hard drive
(L) in my computer and I am able to boot to the second installation.
However, all of my programs and settings from the original installation are
not loaded.

I have 2 questions: does anybody have any new ideas how to recover/repair my
original Windows XP? Is there any way in which I can move the second
installation of Windows XP from my L drive to my C drive and retain my C
drive settings and programs?

Thank you.
