How to fix UNMOUNTABLE_BOOT_VOLUME (0x000000ED) on my Windows XP DELL laptop?

I have a Toshiba Satellite L40. Two days ago, I turned it off by holding the power button and the next day it would not start at all. There is a blue screen with an error : UNMOUNTABLE BOOT VOLUME. I searched all over the net for a solution and did everything I could think of such as using the Windows 7 install disk and trying to repair with the command prompt (check c: /r, bootfix etc.). It runs the check saying there are no errors. However, when I restart I get the blue screen again. Can someone please give me some new solution?

This question was marked as an exact duplicate of an existing question.

Did you try with the Win7 Repair install like posted here? It works fine for me a couple of times, I even can recreate a missing bootloader and \BOOT folder after an file image restore.
