Missing or corrupt file: Windows\AppPatch\drvmain.sdb

Hey Guys.

I just ran into a problem with my D600, when I try to boot up it says I have a missing or corrupt file (windows\AppPatch\drvmain.sdb).  I have an enclosure that I can get to recognize only half of my laptop's hard drive when I open it on my other computer.  The drive is split into two partitions because of a flaw in the Acronis TrueImage program I used when I had a failure with the previous drive.  The first partition had all the system files in it & then the second partition I used for personal files.  It will recognize & let me into the second half of the hard drive.

I get an option when I try to boot up to attempt a repair with the set-up disc that I never got with my laptop.  I have an identical D600 that I can use to get any system files I may need, if at all possible.  Any help would be appreicated beyond belief right now.
