    Download Partition Wizard Free boot disk Free Download Magic Partition Manager Software - Partition Wizard Online
    Burn the .iso, don't just copy it to a CD.
    Boot with the CD and remove "C" from the system reserved partition. Be sure it is still marked active.
    Next change the Windows/data partition to "C".
    When you get it fixed consider making a image of your drive.

    If you have run Startup Repair repeatedly from the System Repair Disk
    and gotten nowhere then confirm that the System Reserved partition is marked Active: Partition - Mark as Active (Method Two)

    Now run Startup Repair 3 Separate Times.

    You can boot free Partition Wizard to mark Active, then click on the Disk # to highlight it, from Disk tab select Rebuild MBR, Apply, reboot. This may preclude the need to run the Repairs from DVD or Repair CD.

    If these fail, mark the Win7 partition Active and try Rebuild MBR and/or Startup Repairs x3.

    You can copy out your files using DVD/Repair CD: Copy & Paste - in Windows Recovery Console

    Then run Factory Recovery from its partition, disks you made or order from Tech Support, or Clean Reinstall with Win7 DVD. Reinstalling Windows 7

    Is your BIOS still pointing at the correct HDD?

    I've had my BIOS decide to try to boot from a different drive (I think that I may have swapped the MB SATA connections though).

    Thanks Guys for all the help and good ideas. I was really out of any. Im still not sure exactly what caused the problem, but I checked out this thread that Wanchoo suggested. The guy was running a Linux system, so if I saw the thread I probibly dismissed it off-hand. but the problem with his OS was similar. BOOTREC.EXE from my recovery disk's command prompt got my HD booting again. Just in time too, the blinking cursur on the black screen of death was begining to mock my futile attempts, but sanity my is retained.
    Thanks again everybody,

    [QUOTE=wanchoo;1750353]Please read the thread "Windows 7 Forums > Windows 7 help and support > Installation & Setup » BOOTMGR is Missing". The Thread Starter was unable to boot till he tried to boot from the System Reserved Partition. Did you try that?

    And finally when all avenues seem closed then the last option remaining is to start all over again by deleting all the partitions and then repartitioning the HD and reinstalling Windows 7 from scratch. This never fails if all the hardware in the computer is functioning properly.
