I have see many posts on this but i am still stalled and wanted to see if i could generate an aha moment from someone.
I am sorry for the length but I have tried many things before posting this.
Here is what I have done so far:

The system has been shut down
I shut down the computer
F8 at startup
Restart 2 attempted to use last known good configuration
Startup failed –BSOD
I shut down the computer
Restart 3 attempted boot into safe mode
Startup failed- BSOD
I shut down the computer
Restart 4 dissable drivers
Startup failed – BSOD
I shut down the computer
Restart 5 - Bootlog (creates ntbtlog.txt)
Windows appeared to be starting – Logo appeared and remained on screen for
Over 20 mins then BSOD
Restart 6 - Directory services restore mode
Startup failed – BSOD
I shut down the computer
Restart 7 - debugging mode

Changed.
The details section displayed.
Details:
System Restore failed to extract the file (D:\Users\Dan\Downloads\Bytecc_floppy_
Disk_Drive_Driver_update_01-2014.exe) from the restore point.
The restore point was damaged or was deleted during the restore.
(The bytecc floppy was an external floppy drive i attempted to incorporate into the system for archiving some old stuff, but it never really worked. but that was a while ago )
I tried both of the restore points that the system offered but they both failed.
Start 3 Command Prompt
Attempted SFC /scannow
Failed There is a system repair pending which requires a reboot to complete. Restart windows and run sfc again.
I tried this a number of times and received the same message.
Start 4 Command Prompt

After I said no a couple of times then I tried yes

So that is it so far. Anyone think I have a prayer of resolving this. I also cloned the drive just in case. My files seem to be in tact as I am able to see them when I attach the clone to my laptop externally.. but I would rather not rebuild the system from scratch..
Thanks
