Yeah I used bootsec repair in DOS/command line mode
tried the Windows recovery CD, doesn't work.
Tried repairing using Windows CD, Dell CD, or USB with ISO. Doesn't work.
System restore sometimes work, sometimes doesn't.
If I use a system image it will restore to a workable form of Windows, but will break again when updating.
I tried windows updating one at a time but with over 100 important updates, it was a big time suck between the reboots, installs, and the repairs when I would find an update, if I could even get past the first crapout. and eventually the boot gets screwed up even if I do a system restore.
