Quote from above:
“I had this problem and managed to fix it without a reinstall.
Create the disc at www.ubcd4win.com on a good pc and boot off of it on the bad one. Once in go to Start, Programs, Registry Tools, Registry Restore Wizard. Tell it where Windows is installed (C:\Windows usually). Then pick the date that you want to roll back to. I chose the one closest to todays date and it recovered it fine. Reboot and bingo! It’s back. (Well it was for me…!)”
