Stop Error: 0x000000ED(0x82F6CE30,0XC0000006,0x00000000,0x00000000

I am trying to fix my Dell laptop, it is giving me the below stop error message:
Stop Error: 0x000000ED(0x82F6CE30,0XC0000006,0x00000000,0x00000000)
Unmountable_Boot_Volume.

I have used the recovery CD with the option to repair, but it stops without completely and has unrecoverable problems noted. I also did the fixboot option, and it still won't start up Windows. I can't get to Safe Mode either. It just runs the startup list and then goes back to the blue stop error screen. Any other suggestions?

Check the article on "When you restart your computer or upgrade to Windows XP, you receive the "STOP 0x000000ED UNMOUNTABLE_BOOT_VOLUME" error message" from here - http://support.microsoft.com/kb/297185

Thanks for the link, but I have already checked that solution and it didnt work for me. Can anyone tell me what the error code is pointing to exactly. I can't seem to find anything related to this exact error codes sequence numbers. Any other ideas as to what to try or is this a lost cause hard drive failure I'm dealing with?

Have you tried to run a chkdsk /r on it? Note that running chkdsk on it may lead to loss of files and user data. Also please try sfc /scannow
