Apologies for leaving you hanging - it was not intentional.
Since the Dell Diagnostics is located on the hard drive, and it loaded for you, it does mean at least that the hard drive has not completely failed. Let's use xPUD to search for the file named in the BSOD and try replacing it with a good copy, if found. It sure can't hurt to try at this point.
Boot to xPUD and open a Terminal window then type in the following command and hit Enter.
find /mnt|grep -ie /ntfs.sys
Jot down the locations and post that back to me.
